Republic Airways Holdings and Mesa Air Group have announced the completion of their merger under a combined company that now holds a fleet of over 310 Embraer E-Jets operating flights under existing capacity purchase agreements for American Airlines, Delta Air Lines, and United Airlines. The transaction was announced on April 7, 2025, and approved by Mesa stockholders on November 17. Now, Republic shareholders own about 88% of the combined company, and Mesa shareholders will own between 6% and 12%.

Both carriers, Republic Airways and Mesa Airlines, still operate under separate air operator’s certificates (AOC). However, now they are trading jointly under the ticker symbol RJET on the NASDAQ Global Select Market.
