If you’re planning on flying out of Lindbergh Field, you might be facing a delay.
United says passengers can anticipate 90 minutes delays on some flights. The issue could affect United's schedule into Wednesday.
Airline spokeswoman Megan McCarthy says United grounded the Boeing 757 aircraft because the carrier determined that it had not completed operational checks after updating air data computers following a 2004 federal directive.
An FAA spokeswoman said United's move was voluntary.
It only affected United's fleet of Boeing 757s. McCarthy says Continental's fleet of 62 757s weren't grounded.
