JetBlue offers you MORE... More value and more certainty for Spirit shareholders More value NOW More value at CLOSING More competition for the Big Four airlines More of the great experience and low fares only JetBlue can offer customers nationwide – a prospect, coupled with the ease of ultra-low-cost carriers expanding and repositioning, that we are confident will result in regulatory approval ...and more opportunities for crewmembers and communities In contrast, Frontier offers significantly less value, no divestiture commitments and no reverse break-up fee despite its similar regulatory profile

JetBlue’s proposal is clearly superior to Frontier’s in all respects Frontier JetBlue Price $30.00 per share offer ($33.00 per share in consensual transaction): now a higher premium to Frontier’s offer value, given market decline $3.3bn1 Equity Value $19.73 total consideration2 per Spirit share $2.0bn Equity Value Consideration All Cash – fully financed with commitments from Goldman Sachs and Bank of America Mostly Stock Value Certainty All cash proposal provides greater value certainty Uncertain given market risk and flawed forecasting processes Transaction value has declined by ~$6 per share / ~$670mm since announcement3 Divestiture Commitment4 Commitment to divest Spirit’s NYC and BOS holdings and additional JetBlue and Spirit assets up to a Material Adverse Effect on Spirit No obligation to make divestitures that adversely impact the Northeast Alliance None Reverse Break-Up Fee4 $200mm (~$1.83 / share; ~8% of Spirit’s share price prior to Frontier announcement and ~45% of Frontier’s original premium) None 1 Assumes fully diluted shares outstanding of approximately 109.5 million per public filings. 2 Represents the implied value of Frontier transaction as of May 20, 2022, based on Frontier’s $9.20 closing share price as of May 20, 2022 and the terms of the Frontier Agreement. 3 Represents decline from Frontier’s $12.39 closing share price as of February 4, 2022 to $9.20 closing share price as of May 20, 2022. 4 Conditional upon negotiated merger with Spirit. + 52% The conflicted Spirit Board’s unwillingness to engage has resulted in a lower offer for Spirit shareholders JetBlue’s proposal offers superior financial value and more certainty due to our regulatory commitments By not giving us access to diligence and rejecting our proposal, the conflicted Spirit Board has deprived its shareholders of the most compelling value creation opportunity. However, it’s not too late. If Spirit’s Board allows minimal diligence, JetBlue is willing to negotiate a consensual deal on the basis of $33 / share

Short-term trading JetBlue offers superior value to Spirit shareholders in any scenario Transaction closes Transaction does not close Frontier Transaction ~$161 ~$202 ~$184 JetBlue Transaction ~$181 $303 up to $333 ~$235 up to ~$255 Source: Bloomberg; market data as of May 20, 2022. 1 Estimated as Spirit’s hypothetical unaffected share price, by applying Frontier’s share price performance between February 4, 2022 and May 20, 2022 to Spirit’s $21.73 closing share price on February 4, 2022. 2 Represents the implied value of Frontier transaction as of May 20, 2022, based on Frontier’s $9.20 closing share price as of May 20, 2022 and the terms of the Frontier Agreement. 3 Represents all-cash proposal made by JetBlue in the current $30 and potential $33 consensual transaction. 4 Estimated by applying the average percentage difference between the Spirit closing share price and the value of the Frontier transaction between February 4, 2022 and April 4, 2022 (the latest trading day before our Proposal was made public) to the $19.73 implied value of Frontier transaction as of May 20, 2022. 5 Low end of the range estimated applying the average spread between $33 and Spirit’s closing share price between April 5, 2022 (when our proposal was made public) and April 29, 2022 (the last trading day before our proposal was rejected by the Spirit Board) to $30; high end of the range estimated with reference to Spirit’s average closing share price between April 5, 2022 and April 29, 2022.

NEA is irrelevant for Spirit… JetBlue to divest Spirit’s holdings in NYC and BOS JetBlue’s NEA – either approved by the courts or blocked – does not hinder a JetBlue-Spirit transaction Market shares are basically the same… JetBlue / Spirit combined market share of 8%1 Frontier / Spirit combined market share of 7%1 JetBlue has a more significant impact on legacy carrier fares… JetBlue’s presence on a nonstop route decreases legacy fares by ~16%, or 3x as much as ultra-low-cost carriers Legacy carriers do not respond to ULCCs in the same manner as JetBlue; their fares remain higher JetBlue irreplaceable unlike ULCCs… JetBlue offers a unique value proposition that is difficult to replicate Ultra-low-cost carriers thrive with smaller networks and are expanding rapidly (e.g., Frontier has 230 aircraft on order, Breeze and Avelo expanding rapidly) JetBlue has far less overlap with Spirit than Frontier has… JetBlue overlaps with Spirit on 54 nonstop routes2 and only 31 routes2 when excluding the NEA-relevant markets, which JetBlue has offered to divest Frontier overlaps with Spirit on 104 nonstop routes2 JetBlue offers Spirit shareholders strong protections4 Commitment to divest assets up to a Material Adverse Effect on Spirit (including all Spirit NYC and BOS holdings) $200mm reverse break-up fee No divestiture commitment, despite similar regulatory profile No reverse break-up fee Could walk away from the merger without any penalty if transaction does not close for antitrust reasons JetBlue has high conviction in obtaining regulatory approval… … Spirit’s focus on Northeast Alliance is a red herring Frontier JetBlue 1 Based on 2021 nonstop US passenger seats (ending December 2021). 2 Based on Q1-Q4 2021 domestic Department of Transportation data. 3 Based on scheduled flights / seats / ASMs for 2021 including international routes. 4 Conditional upon negotiated merger with Spirit. JetBlue has far less overlap in flights, seats, and ASMs with Spirit than Frontier in the metropolitan areas served by both3

Spirit’s Board is entrenched and conflicted Multiple Spirit Directors involved in the decision to merge with Frontier have significant ties to Bill Franke, who appointed each to the Spirit Board Length of tenure and known conflicts display poor governance Frontier has promised Board seats on the combined entity to 5 out of the 8 current Spirit Directors The conflicted Spirit Board has not acted in its shareholders’ interest Entrenchment resulting in a flawed process Key themes Frontier transaction results from a fundamentally flawed process Spirit and Frontier have periodically explored the possibility of a business combination in the past, without ever seriously considering any alternative Spirit negotiated with Frontier for 8 months prior to signing but failed to perform a market check The conflicted Spirit Board clearly made no attempt to extract more value from Frontier for the Spirit shareholders, even after JetBlue’s enhanced proposal No constructive engagement with JetBlue Limited diligence information provided to JetBlue Unreasonable and off-market regulatory requests that were not required in Frontier transaction No good faith engagement to negotiate a transaction

Vote against the Frontier transaction at the Spirit special meeting Exercise your appraisal rights Tender your shares in JetBlue’s tender offer Spirit shareholders have an important choice to make about their investment; vote against the Frontier transaction on June 10 and exercise your appraisal rights What we are asking Spirit shareholders to do

Spirit shareholders should vote AGAINST the Frontier transaction and also exercise appraisal rights they are entitled to under Delaware law Section 262 of the Delaware General Corporation Law provides Spirit shareholders with appraisal rights which could apply in the event the Frontier transaction is approved The exercise of appraisal rights ultimately results in a court process in which a court will determine the fair value of the Spirit shares and require that amount to be paid 100% in cash Spirit is worth more than the value of the Frontier transaction; in determining the fair value of Spirit’s shares, the court would consider certain factors including standalone DCF values and that JetBlue’s superior all-cash proposal of $30 per share values Spirit at a significant premium to the Frontier transaction When Spirit shareholders perfect their appraisal rights and a court determines the appropriate stand alone value for Spirit, the combined Frontier-Spirit will be required to pay that amount in cash to the dissenting shareholders

Key takeaways

Key takeaways for Spirit shareholders JetBlue offers superior value to Spirit shareholders JetBlue has strong conviction in its ability to close – Spirit’s regulatory objections have no merit Spirit’s Board is entrenched, conflicted, has failed to maximize shareholder value, and ignores the similar regulatory profile of the Frontier transaction JetBlue proposal provides a superior alternative with more benefits for all stakeholders as well as enhanced regulatory protections

Market Reaction Contrast Spirit Share Price History The market reaction is clear; the JetBlue offer is good for Spirit shareholders and the conflicted Spirit Board continues to make decisions that are detrimental to Spirit shareholder value Every constructive piece of news around the JetBlue proposal has sent the Spirit stock soaring Source: Bloomberg; market data as of May 20, 2022. On April 5, when our initial proposal leaked in late afternoon, Spirit’s stock price increased ~28% by the close On May 16, when we disclosed our tender offer, Spirit’s stock price increased ~10%+ On the same day, after Spirit issued a press release announcing their Board would review our offer, the stock rose a further ~2% by the close On May 2, when the conflicted Spirit Board rejected our proposal, the Spirit stock declined 9%+ on the day Between May 3 and May 13, while there was no new information made public about our proposal, the Spirit stock declined a further 20%+, underperforming other airlines by 10% On May 19, when the conflicted Spirit Board urged shareholders to reject the JetBlue tender offer, the stock dropped ~2% +28% +10% -20% -9% -2% 5-Apr JetBlue proposal leaks 2-Apr Conflicted Spirit Board rejects JetBlue proposal 3-May to 13-May No news flow around proposal between Spirit rejection and tender offer 16-May JetBlue files proxy statement and commences tender offer 19-May Spirit Board urges shareholders to reject JetBlue tender offer

JetBlue has strong conviction in its ability to close – the conflicted Spirit Board’s regulatory argument is a red herring

Spirit regulatory arguments are unfounded Regulatory facts Spirit claims “The JetBlue Effect on fares is not real…” The JetBlue Effect is established and flourishes today “The JetBlue deal is about a high-cost, high-fare airline buying a low-cost, low-fare airline…” Fundamentally, the JetBlue-Spirit transaction is about creating the best positioned national challenger to the dominant “Big Four” carriers “JetBlue’s Northeast Alliance is antithetical to Spirit Transaction…” JetBlue has made a commitment to divest Spirit’s assets at Northeast Alliance airports Northeast Alliance litigation (regardless of outcome) is irrelevant to closing of JetBlue-Spirit “Frontier’s transaction has materially less risk than JetBlue’s…” Frontier transaction has far more route overlap than JetBlue and combination would have very similar market share to JetBlue + Spirit Spirit and Frontier have received in-depth DOJ information requests JetBlue has strong conviction in its ability to close, and supports it with a significant divestiture commitment1 and a substantial reverse break-up fee1. JetBlue will weigh incremental regulatory concessions against the payment of a reverse break-up fee 1 Conditional upon negotiated merger with Spirit.

The “JetBlue Effect” is real, demonstrable, and foundational to its business model… The “JetBlue effect” is widely recognized and longstanding; as recently as 2021, the Department of Justice recognized its benefits1: “JetBlue’s reputation for lowering fares is so well known in the airline industry that it has earned a name: the ‘JetBlue Effect.’ JetBlue’s record in Boston and New York City illustrates why.” “In the face of consolidation, JetBlue has provided an important and steadfast source of competition.” “JetBlue is uniquely disruptive… as a result, JetBlue has a long and public track record of significantly lowering fares when it enters a market.” “[JetBlue] has saved consumers a total of more than $10 billion since the airline’s founding, offering lower fares and better service and forcing competitors to do the same.” A 2013 study from the MIT International Center for Air Transportation2 concluded that “JetBlue is now the airline that is associated with the largest decline in average fares at U.S. airports” 1 Source: September 2021 DOJ complaint and press release. 2 “Evolving Trends of U.S. Domestic Airlines,” MIT Airline Industry Consortium Study (August 2013). JetBlue is and has been the most significant challenger airline in lowering legacy fares on the routes it flies

… and continues to deliver consumer benefits today DOT data analysis as recent as this year supports the fact that JetBlue’s presence on a nonstop route decreases legacy fares ~16%, three times more than even Spirit’s (~5%) Since the 2013 MIT study, JetBlue has launched service on each of the routes below and continues to serve each today – in every case, prices declined significantly after JetBlue entry BOS-LGA FLL-LAS MCO-SLC +48% (36%) +26% (16%) +97% (26%) +69% (14%) +43% (19%) Passengers Daily Each Way (PDEWs) BUF-LAX JFK-ATL Source: DOT data via Cirium. PDEWs and Avg. Fare prior to JetBlue entry represents most recent full year average daily passengers and one-way fare. PDEWs and Avg.

Fundamentally, the JetBlue-Spirit transaction creates a platform for sustainable growth and establishes a national challenger to the ‘Big Four’ 171 Combined flights at strategic Fort Lauderdale focus city 455 Combined fleet size 312 Aircraft in order book Source: 2021, 2019 company filings; number of daily flights and destinations are based on April 2022 schedule data as of March 25, 2022. 130+ Total destinations Increased network and customer relevance Combined network will turbocharge JetBlue focus city strategy: Provides immediate benefit in existing focus cities (FLL, LAX, MCO) Diversifies network Complements existing NEA strategy Leverages a common leisure and VFR customer base Access to new assets and deeper crewmember base Combined asset base provides sustainable growth: Facilitates access for future growth (ATL, LAS, ORD) Mitigates aircraft availability risk and optimizes manufacturer support Enhances fleet commonality and simplifies integration while increasing optionality Accelerates transition to new engine technology Unifies crewmember bases, establishing fair wages for all and creating more opportunities for growth Expands JetBlue Effect Product offering will bring the JetBlue Effect to more customers and communities: JetBlue reduces legacy fares in the markets it enters significantly more than ULCCs Positions JetBlue as a more relevant low-cost carrier in a concentrated US market Expands our award-winning customer service to a multitude of new markets Provides a customer-centric alternative to legacy hub networks

Access to Spirit assets enhances JetBlue’s relevance in legacy hubs, bringing the JetBlue effect to significantly more customers paying high fares JetBlue’s contemplated combined network plan includes: ~120 new domestic non-stop routes, bringing more than $500 million of annual consumer savings to customers on those routes via the JetBlue Effect Enhances JetBlue’s unique ability to drive market relevance in key legacy hubs like South Florida and Los Angeles Strong divestiture commitment to provide ULCC(s) access to Spirit’s NYC and Boston infrastructure and access to Fort Lauderdale growth A unique product offering aimed at serving a wider array of customer demographics (e.g., leisure, VFR, premium, small and large businesses, etc.) Note: Based on average departures/day per respective schedule for April 2022 for JetBlue and Spirit.

ULCC competition will continue to grow… ULCC expansion will combat any potential negative effects from the JetBlue-Spirit transaction ULCC model does not require scale or brand awareness ULCCs are growing rapidly Frontier, with 110 aircraft already, has 230 new Airbus planes on order Sun Country launched 34 new markets in 2021 Allegiant reported flying more capacity in 2H21 than in 2019 Avelo and Breeze launched in the first half of 2021 Avelo expects its fleet will consist of at least 15 737 NGs by the end of 2022 Breeze is already flying 15 planes, with plans to take delivery of one new plane/month for the next six years (reaching more than 80 total aircraft by 2029) Midwest Express announced in April 2022 that it plans to return Precedent transactions show courts credit new market entrants in decision to allow mergers to proceed (e.g., Sprint / T-Mobile)

The Northeast Alliance, a limited, pro-competitive, alliance between JetBlue and American, unlocks growth in one of the nation’s most constrained regions, the Northeast, and is guided by four main principles: Remain independent companies Optimize the use of JetBlue’s and American’s assets including slot and gate infrastructure Create a seamless customer experience to maximize use of the combined global network Incentivize mutual growth and offer customers a viable third competitor in the region Limited geographic scope (BOS, JFK, LGA, and EWR) JetBlue and American remain fierce competitors, as shown by JetBlue’s pursuit of Spirit, which provides JetBlue with complementary growth beyond the Northeast JetBlue is committed to ensuring the success of both Northeast Alliance facilitates competition in an otherwise constrained geography, controlled by two legacy carriers JetBlue forecasted growth within NEA geography Overview of the Northeast Alliance The Northeast Alliance and the Spirit transaction are complementary and enable JetBlue to become a compelling national challenger Note: Based on JetBlue average departures/day for August 2019 and management projections. Sources: Diio MI, DOT data.

The Northeast Alliance turbocharges JetBlue’s ability to compete in the Northeast, already delivering consumer benefits Unlocks JetBlue growth in an otherwise constrained geography, with stated commitments to grow seats at JFK and LGA by 15% by 2025 JetBlue will fly 52 daily flights from LGA in August using larger E-190 and A320/1 aircraft, made possible by access to 35 American Airlines slots, which were previously on smaller regional jets JetBlue is committed to divesting Spirit’s holdings in NYC and Boston to address any overlap upfront The Northeast Alliance trial will begin in September, and will be decided long before the resolution of any challenge to the Spirit transaction The conflicted Spirit Board’s arguments about the Northeast Alliance are baseless; the Northeast Alliance is pro-competitive and the litigation outcome irrelevant Potential litigation outcomes Northeast Alliance strategic rationale Source: Cirium. JetBlue expects to win the Northeast Alliance litigation, reinforcing its pro-competitive nature. The outcome is irrelevant for the regulatory approval of the Spirit transaction Will JetBlue win the NEA litigation? Yes No NEA determined to be pro-competitive Provides judicial support for benefits of JetBlue growth NEA blocked NEA no longer relevant to Spirit acquisition JetBlue-Spirit wins

“Blocking the alliance would ultimately prove anti-competitive. […] The American and JetBlue alliance has been focused on growth in the Northeast which could not have been achieved without additional scale.” –MKM Partners “JBLU is in competitive markets (New York, Boston, Florida), but its alliance with AAL should add more competitive choice in New York/Boston and make it more relevant to business travelers.” –Bank of America “Missing in the recently filed lawsuit by the DOJ was any acknowledgement that American and JetBlue’s Northeast Alliance (NEA) has effectively created a viable third competitor in in the region, particularly New York. Thus far, the two carriers under their NEA have announced at least 60 new airport pairs, many of which have increased the number of competitors in a particular market from 1 to 2 and 2 to 3 (and some markets are entirely new, which we believe are meaningful wins for consumers). –Deutsche Bank “The DOJ is concerned about losing a "Maverick Competitor," a recognized antitrust doctrine that applies to an airline that keeps others honest by containing industry fare increases. […] we can't help but conclude that the DOJ would have a hard time winning this case.” –Seaport Pro-competitive nature of Northeast Alliance recognized by industry analysts Analysts also view the Northeast Alliance as pro-competitive and expect JetBlue to prevail in DOJ lawsuit

Market share (2021) Pro forma Spirit + JetBlue Pro forma Spirit + Frontier Source: Based on 2021 nonstop US passenger seats (ending December 2021). JetBlue + Spirit would have a combined 8% market share vs. 7% for Frontier + Spirit – a single percentage point of difference – which is completely misrepresented by the conflicted Spirit Board The conflicted Spirit Board pretends there is a big difference in regulatory risk but BOTH deals create the number 5 player with very similar market share

Frontier’s Announced Synergies (in $ Millions) "Review [of] the HHI impact at key airports under each merger […] The impacts are modest under both mergers with the exception of FLL and SJU under the JetBlue-Spirit deal. However, when considering South Florida as a whole, i.e., combining MIA and FLL, the impact is modest. Moreover, JetBlue’s resulting increased Florida exposure (lowering reliance on the Northeast) could also reduce DOJ’s concern around American’s undue influence with the NEA." –Raymond James “We believe the proposed transaction has merit and would pass muster with regulators We are of the view that JetBlue’s proposed acquisition of Spirit would not be blocked by regulators given the modest route overlap between both airlines.” –Deutsche Bank “We see a path for either the JetBlue-Spirit or Frontier-Spirit merger to be cleared. Most notably, we believe there is a misconception on the level of overlap and see little variance in competitive implications outside of Fort Lauderdale airport (FLL)...” –Raymond James “Frontier has a checkered history with respect to network planning (lacks staying power in its markets). JBLU combined with SAVE, in contrast, offers greater network stability for growth and thus, would be a more formidable competitor to the Big Four” –Seaport Spirit has significantly overstated and misrepresented the relative regulatory risk of JetBlue’s proposal and ignores its own regulatory risk Independent industry observers see similar regulatory profile for both Frontier and JetBlue transactions “If I were a Spirit shareholder, I would be irate with the airline’s board for not more seriously entertaining an acquisition offer from JetBlue...a deal between Spirit and JetBlue might be somewhat more difficult to get past regulators than a merger with Frontier, but not 50% harder.” –United Airlines CEO, Scott Kirby “...the [Frontier] deal threatens excessive competition on several dozen city pairs...moreover, a [Frontier] deal eliminates competition between the two largest ULCCs...” –National Law Review

Frontier has much more overlap with Spirit than JetBlue No matter how you cut it, Frontier has greater overlap on nonstop routes with Spirit A third-party assessment determined only 11% of JetBlue and Spirit nonstop routes overlap with each other, compared to 18% overlap for Frontier and Spirit1 In 2021, JetBlue overlapped with Spirit on 54 nonstop routes2 (and 31 routes2 when excluding NEA-relevant markets), compared to Frontier’s 104 overlapping nonstop routes2 JetBlue transaction comes with less overlap in flights, seats, and ASMs than the Frontier transaction in the metropolitan areas served by both3 1 CNN Business, April 6, 2022. 2 Based on Q1-Q4 2021 domestic Department of Transportation data. 3 Full-year data for both 2019 and 2021 based on scheduled flights/seats/ASMs. 2021 2019 Airline Flights Seats ASMs 2021 ex.

Spirit’s Board is entrenched, conflicted and has failed to maximize shareholder value

Spirit Board is conflicted and is not serving its shareholders’ best interests Until 2013, Indigo Partners, Bill Franke’s investment firm and the majority shareholder of Frontier, controlled Spirit Airlines Multiple Spirit Directors involved in the decision to merge with Frontier have significant ties to Bill Franke, who appointed each to the Spirit Board Length of tenure and known conflicts display poor governance Frontier has promised Board seats on the combined entity to 5 out of the 8 current Spirit Directors Shareholders should be concerned that the Spirit Board is only serving the interests of Frontier / Indigo Partners Appointed by Bill Franke and succeeded Franke as Chairman of Spirit in 2013 Personally leading negotiations on behalf of Spirit and on the other side of Franke since June 2021 Ted Christie Carlton Donaway Mark Dunkerley Barclay Jones Robert Johnson Christine Richards Myrna Soto Dawn Zier Mac Gardner (Chairman) Appointed by Bill Franke Former Frontier executive Composition of the conflicted Spirit Board at time of Frontier announcement

Spirit Directors negotiated with Frontier for ~8 months without calling JetBlue – to the clear detriment of Spirit shareholders 1 Represents premium of Frontier offer value, using per share pro forma equity value of Spirit / Frontier, over the Spirit undisturbed price of $21.73 on February 4, 2022. 2 Reflects median premium to unaffected price of target in precedent of precedent Low Cost Carrier transactions (WestJet-Onex, Virgin America-Alaska, AirTran-Southwest, ExpressJet-Skywest, Midwest Air/TPG & Northwest). 3 Based on the “Spirit DCF Range” of $34.00 to $64.00 per Spirit share included in the “Opinion of Barclays Capital Inc”, and Spirit Discounted Cash Flow Analysis resulting in $33.00 to $55.50 range of implied equity value per Spirit common stock, included in the “Opinion of Morgan Stanley & Co. LLC” sections of the Spirit Definitive Proxy Statement filed on May 11, 2022. 4 Estimated based on the events occurred on December 15, 2021, described in “Background of the Merger” section of the Spirit Definitive Proxy Statement filed on May 11, 2022. Spirit was in discussions with Frontier for 8 months, yet never reached out to other potential buyers – an astounding failure to try to secure a better offer for Spirit shareholders Discussions between Spirit and Frontier began in 2016 – tunnel vision that Spirit / Frontier combination was their only destiny 8 months of exclusive discussions No market check of potential alternative acquirors Once JetBlue made its proposal, the conflicted Spirit Board did not extract any concessions from Frontier ~10%1 economic premium vs. ~86%2 average headline premium for airline transactions Sale value at level below financial advisor range3 Only 6% improvement from initial to final offer4 Limited governance in the combined company No regulatory divestiture commitment or reverse break-up fee

The conflicted Spirit Board has continuously stonewalled JetBlue Misled investors about its willingness to negotiate with JetBlue; it did not engage in good faith Provided very limited information making it impossible for JetBlue to complete its due diligence Responded to JetBlue’s initial proposal only after a significant delay and after the JetBlue proposal was made public, and then made contractual demands that were unprecedented in airline transactions Not once did Spirit attempt to renegotiate with Frontier While JetBlue acted in good faith and gave the conflicted Spirit Board the benefit of the doubt for over a month, the Spirit Board’s real objective was to defend the inferior transaction with Frontier

JetBlue proposal provides a superior alternative with more benefits for all stakeholders
