American Airlines has joined Emirates and Ryanair in calling for Boeing to return to delivering airplanes on time. They are frustrated, as are many carriers around the world with delayed aircraft deliveries. With the 777X recently pushed back to 2026 and production currently stopped on the 737 MAX, 767, and 777, customers are increasingly concerned about maintaining routes and expensive maintenance to keep older aircraft flying. The longer Boeing's problems continue, the more difficult it becomes for airlines to meet their aircraft needs.
