DALLAS (CBSDFW.COM/AP) – Southwest Airlines is removing flights with the troubled Boeing 737 Max aircraft from its schedule through August 5, a period that includes the peak of the airline’s busy summer travel season.

The company did not specify how many flights would be cancelled because of the new schedule. The 737 Max was grounded in the U.S. on March 13, after a deadly crash involving one of the planes in Ethiopia. That accident, on March 10, was the second fatal crash involving the airplane.
