American Airlines has extended its cancellations for its Boeing 737 Max aircraft until August, according to published reports.
The airline's CEO Doug Parker and President Robert Isom issued a statement saying it would cancel 115 flights daily through August 19, representing approximately 1.5 of the airlines' flying each day during the summer.
Senior officials at American Airlines said they were "confident" that the Boeing upgrade would be approved by United States aviation regulators before 19 August, despite its decision to ground its fleet of 24 planes until then. The airline said about 115 flights per day would be canceled.More news: Masters 2019: Bettor wins $1.19 million on Tiger Woods' green jacket win
America's leading airline had previously only planned to keep the planes out of commission until June 5, with Boeing facing intense scrutiny after 157 people died in an Ethiopian Airlines 737 MAX crash on March 10 - the second deadly crash involving the aircraft in five months.
The airline said not all scheduled flights with MAX aircraft will be canceled - it may substitute other planes. But by extending cancellations through the summer, the airline can plan more reliably for the peak travel season, said Doug Parker, American's chairman and CEO, and Robert Isom, president, in a letter to employees Sunday.
They added that the airline has been in close contact with the FAA, the Department of Transportation, the National Transportation Safety Board and global regulators and are "pleased with the progress so far".More news: Ray tracing now available on Nvidia GTX GPUs
Investigators are focusing on the plane's anti-stall software, the Manoeuvring Characteristics Augmentation System (MCAS).
"My team and I are working closely with our customers to answer their questions, get their feedback and ensure those who operate the Max are prepared when the grounding is lifted and the fleet returns to flight", Muilenburg said.
Parker and Isom said they are "confident" in Boeing's impending software updates and new training proposals, and remain in continuous contact with regulatory authorities over the MAX recertification process. USA safety regulators have to approve the fix and decide on new training for pilots. For one test flight in early April, Muilenburg joined the pilots on one of the planes.More news: Respawn Co-Founder Jason West Has Joined Epic Games
