Revenue from Contract with Customer [Abstract]  
REVENUE REVENUE
Sun Country is a certificated air carrier generating Operating Revenues from Passenger (consisting of Scheduled Service, Charter, and Ancillary), Cargo and Other revenue. Scheduled Service revenue mainly consists of base fares. Charter revenue is primarily generated through service provided to the U.S. Department of Defense ("DoD"), collegiate and professional sports teams, and casinos. Ancillary revenue consists of revenue earned from air travel-related services, such as: baggage fees, seat selection fees, other fees and on-board sales. Cargo consists of revenue earned from flying cargo aircraft for Amazon.com Services, Inc. (together with its affiliates, “Amazon”) under the Amended and Restated Air Transportation Services Agreement (the “A&R ATSA”). Other revenue consists primarily of revenue from services in connection with Sun Country Vacations products and rental revenue related to certain transactions where the Company serves as a lessor. The Company recognized rental revenue of $10,981 and $9,873, during
the three months ended June 30, 2025 and 2024, respectively; and $19,617 and $19,148 during the six months ended June 30, 2025 and 2024, respectively.
In June 2024, the Company entered into the A&R ATSA with Amazon that will increase the number of Boeing 737-800 cargo aircraft that Sun Country operates on behalf of Amazon from 12 to 20 in 2025. For more information on the A&R ATSA, see Note 2, "Basis of Presentation and Summary of Significant Accounting Policies" included within Part II, Item 8 of the 2024 10-K. During the six months ended June 30, 2025, the Company received seven additional cargo aircraft under the A&R ATSA, of which three aircraft were in-service. Subsequent to June 30, 2025, the Company received the eighth and final aircraft. As of the date of this filing, five aircraft were in-service. All eight additional aircraft are expected to be in-service by the end of the third quarter of 2025.

The Company attributes and measures its Operating Revenues by geographic region as defined by the U.S. Department of Transportation ("DOT") for airline reporting based upon the origin of each passenger and cargo flight segment.
The Company’s operations are highly concentrated in the U.S., but include service to many international locations, primarily consisting of scheduled service to Latin America and military charter service to various international destinations.

Contract Balances
The Company’s contract assets primarily relate to costs incurred to prepare the Amazon cargo aircraft for service under the original ATSA and the A&R ATSA, as well as warrants that have vested and will be amortized against Cargo revenue over the remaining term of the A&R ATSA. The balances are included in Other Current Assets and Other Assets on the Condensed Consolidated Balance Sheets.
The Company’s contract liabilities are primarily comprised of: 1) ticket sales for transportation that have not yet been provided (reported as Air Traffic Liabilities on the Condensed Consolidated Balance Sheets), 2) outstanding loyalty points that may be redeemed for future travel and other non-air travel awards (reported as Loyalty Program Liabilities on the Condensed Consolidated Balance Sheets) and, 3) the Amazon Deferred Up-front Payment received under the original ATSA (reported within Other Current Liabilities and Other Long-term Liabilities on the Condensed Consolidated Balance Sheets).
Contract Assets and Liabilities are as follows:
June 30, 2025December 31, 2024
Contract Assets
Amazon Contract$8,553 $4,135 
Total Contract Assets$8,553 $4,135 
Contract Liabilities
Air Traffic Liabilities$106,599 $160,686 
Loyalty Program Liabilities14,397 14,601 
Amazon Contract1,865 1,612 
Total Contract Liabilities$122,861 $176,899 
The balance in the Air Traffic Liabilities fluctuates with seasonal travel patterns. Most tickets can be purchased no more than 12 months in advance, therefore any revenue associated with tickets sold for future travel will be recognized within that timeframe. For the six months ended June 30, 2025, $151,101 of revenue was recognized in Passenger revenue that was included in the Air Traffic Liabilities as of December 31, 2024.
Loyalty Program
The Sun Country Rewards program provides loyalty awards to program members based on accumulated loyalty points. The Company records a liability for loyalty points earned by passengers under the Sun Country Rewards program using two methods: 1) a liability for points that are earned by passengers on purchases of the Company’s services is established by deferring revenue based on the redemption value, net of estimated loyalty points that will expire unused, or breakage; and 2) a liability for points attributed to loyalty points issued to the Company’s co-branded credit card holders is established by deferring a portion of payments received from the Company’s co-branded agreement. The balance of the Loyalty Program Liabilities fluctuates based on seasonal patterns, which impacts the volume of loyalty points awarded through travel or issued to co-branded credit card and other partners (deferral of revenue) and loyalty points redeemed (recognition of revenue). Due to these reasons, the timing of loyalty point redemptions can vary significantly.
Changes in the Loyalty Program Liabilities are as follows:
20252024
Balance – January 1$14,601 $13,737 
Loyalty Points Earned4,852 4,519 
Loyalty Points Redeemed (1)

Balance – June 30
$14,397 $13,272 
______________________
(1)Loyalty points are combined in one homogenous pool, which includes both air and non-air travel awards, and are not separately identifiable. As such, the revenue recognized is comprised of points that were part of the Loyalty Program Liabilities balance at the beginning of the period, as well as points that were earned during the period.
In March 2025, the Company entered into a Credit Card Program Agreement for a new co-branded credit card program. The new co-branded credit card program is expected to launch in the second half of 2025. Subject to certain exceptions, the Credit Card Program Agreement has a term of seven years following its launch, with automatic successive one-year renewal terms.
