On Dec. 22, the carrier announced that it will add 23 additional MAX 9s to its Boeing order, for a total of 68 MAX 9s to be delivered by 2024.Both United and Alaska will allow nervous flyers to make free changes for flights booked on the MAX.

All recertified jets must receive software updates to the flight control systems, which takes just four hours, according to one of American Airlines’ top mechanics.Pilots must also undergo new required training before they fly the plane once again. In a recent media tour, Capt. Alan Johnson, American’s senior manager for flight standards, said that recertifying the MAX “has been a pilot-led initiative, and we’re trying to honor the sacrifice of the 346 souls moving forward.”American Airlines became the first U.S.-based carrier to fly a commercial MAX flight, just about two weeks after the ungrounding order. The Fort Worth-based carrier invited members of the media on a demonstration flight, which included a two-hour stop at the airline’s Tulsa maintenance facility to learn more about the updates being made to the beleaguered jet.American’s 737 MAX 8 preparing for its first demo flight (Photo by Zach Griff/The Points Guy)In the weeks leading up to AA’s first revenue MAX flight on Tuesday, Dec. 29, the carrier has been flying employee-only flights, in a bid to “ensure our employees are comfortable.“More: A pilot and mechanic explain what’s needed to bring the 737 MAX backBrazil-based GOL Airlines operated the first revenue MAX flight worldwide on Dec. 9.
