An American Airlines Boeing 737 Max 8, on a flight from Miami to New York City, comes in for landing at LaGuardia Airport in New York, March 12, 2019.
Southwest Airlines removed the Max jet from its schedule through Aug. 5. United has canceled Max flights through June 5.
“We remain confident that the impending software updates, along with the new training elements Boeing is developing for the MAX, will lead to recertification of the aircraft soon,” American CEO Doug Parker and President Robert Isom wrote in a letter to employees Sunday.
Parker also said canceling the flights now will help the airline plan for its busiest travel season of the year.
As major airlines continue to extend cancellations, Boeing said Thursday that it’s completed 96 flights with the new Max software fix. The planemaker will likely submit the fix to Federal Aviation Administration regulators within the next couple weeks.
