American Airlines is removing the Boeing 737 MAX from its schedule until early April, a month later than it had been planning.
It's just the latest delay as Boeing struggles to fix software and computers on the plane after two fatal crashes.
American said it pushed back the planned return of the MAX after conversations with the Federal Aviation Administration, the Transportation Department and Boeing.
The airline said it could operate flights with only employees and invited guests on board before April 7 if the FAA certifies the plane.
