A new airline emerges with a huge fleet of Brazilian planes after Republic Airways Holdings officially announced, on November 25, 2025, the merger between Republic Airways and Mesa Air Group.
Furthermore, the agreement, approved by Mesa’s shareholders on November 17, transforms the two companies into the second largest regional airline in the United States, bringing together no less than 310 Embraer jets, the largest fleet of the model in operation worldwide.
