Two weeks ago, American Airlines confirmed it would keep its order of Boeing 737 MAX but now, the situation changed completely as it started threatening to cancel a part of it. The apparent reason for that is the airline’s struggle to secure financing for the 17 of 737 MAX, which were expected to be delivered in 2020.

According to the reports, American Airlines’ executives have informed Boeing about the insufficient financing and asked the company for help in securing the funding. Should that be unsuccessful, the company would have no other option but to cancel the order of 17 new aircraft.

The decision is extremely inconvenient for Boeing, especially when American Airlines, Boeing’s 10th biggest customer, was the one to urge the company to develop and manufacture a narrow-body aircraft that would be more fuel-efficient, which caused the birth of 737 MAX.

American Airlines are among many other companies implementing cancellations of the Boeing 737 MAX orders, which sum up to 600 since the beginning of the year. This makes an already difficult time for Boeing even worse; although not all of the orders have been starting to implement, the number of newly built aircraft sitting on the ground of the company’s facilities is definitely increasing.
