Alaska Airlines has completed its first flight on a 737 Max.
Alaska Flight 482 took off from Seattle at 6:42 a.m. local time Monday and touched down in San Diego at 9:09 a.m., according to Flight Aware.
The carrier took delivery of its first Max in late January and expects to take delivery of a total of 13 of the aircraft this year. Over the coming four years Alaska expects to receive 68 Boeing Max planes.
With Monday's flight, Alaska has become the fourth U.S. Max operator, joining American, United and Southwest. American and United have already resumed flying the plane. Southwest will do the same on March 11.
The Max was grounded by the FAA for 20 months in 2019 and 2020 due to flaws in its automatic flight control software that led to two crashes and 346 deaths.
