American Airlines, one of the largest Boeing 737 MAX operators in the world, with 24 planes currently grounded and 76 still on the order list, announced extending cancellations for the Boeing 737 MAX aircraft flights through 19 August.

Last week world’s largest airline said it extends cancellations until early June, meanwhile, recent announcement made this time longer. American Airlines revealed until 19 August approximately 115 flights per day will be cancelled. It “represent approximately 1.5 percent of American’s total flying each day this summer”.

“Based upon our ongoing work with the Federal Aviation Administration (FAA) and Boeing, we are highly confident that the MAX will be recertified prior to this time”, said American’s Chairman and CEO Doug Parker and President Robert Isom to American team members in a statement.

Boeing 737 MAX fleet was globally grounded in March after the Ethiopian Airlines crash. It was already the second deadly accident involving Boeing 737 MAX 8 aircraft. Both accidents claimed the lives of 346 people.

Although investigation of both accidents is still underway, preliminary reports put their biggest focus on MAX automatic safety system. Following the indications received from the investigation teams, Boeing is currently working on updating its software to make MAX planes even safer.

Therefore, Boeing released no information on the date it plans to make its MAX fleet airborne again.
