Boeing paid Alaska Airlines $160 million for 737 retirement. Boeing could also face payments to other companies.

Boeing has already spent a lot of money because of the weeks-long shutdown of its 737 Max 9 aircraft after a near-miss in January. A United Boeing also landed in March with a hole in its exterior paneling, and the important 737 Max aircraft also failed dozens of safety tests. To make matters worse, the cockpit crew of a United Airlines flight in March has now reported possible technical defects.
