Collective Bargaining Agreements Collective Bargaining Agreements
As of December 31, 2025, Air Wisconsin had five collective bargaining units. The Airline Pilots Association (“ALPA”) represents pilots. The Association of Flight Attendants-CWA (“AFA”) represents flight attendants. The International Association of Machinists and Aerospace Workers AFL-CIO (“IAMAW”) represents both mechanics and technical store clerks under two separate collective bargaining agreements. The Transport Workers Union of America (“TWU”) represents dispatchers.
Air Wisconsin had reached a new agreement with ALPA and its pilots which became effective in October 2023 and with TWU and its dispatchers in April 2024. Additionally, as of December 31, 2025, Air Wisconsin was in negotiations with both AFA and its flight attendants, and IAMAW and its mechanics and clerical employees.
Amendable dates for each bargaining unit are:

The unionized workforce and related labor agreements remained with Air Wisconsin following the Aviation Disposition, so the Company is no longer party to any collective bargaining agreements.
