The US-based American Airlines is extending the cancellation of its Boeing 737 Max 8 flights from June until mid-August, the Boeing model was controversial after it involved in twin crash in Indonesia and Ethiopia.
The move is to “provide confidence” to customers during the peak summer travel season, the airline said in a statement.
Last month, 737 Max aircraft were grounded worldwide following fatal crashes involving Ethiopian Airlines and Indonesia’s Lion Air.
Boeing is developing new software for the jet’s anti-stall system, which has come under scrutiny since the crashes.
American Airlines senior officials said they were “confident” that the Boeing upgrade would be approved by US aviation regulators before 19 August, despite its decision to ground its fleet of 24 planes until then.
Furthermore, the cancellations will affect up to 115 flights a day, Reuters news agency reported.
Last week, Southwest Airlines made a similar move and United Airlines has also cancelled 737 Max 8 flights until June.
The plane is grounded as investigations continue into the Ethiopian Airlines crash last month which killed all 157 people on board.
