Flights resumed after a computer problem stopped all American Airlines flights and reservations Tuesday afternoon, April 16, 2013.

The company called it a “system-wide ground delay” in an online announcement.

Just before the delay was announced, American Airlines reported a problem with intermittent outages for people trying to book reservations.

The online schedules for Quad City International Airport indicated an American flight scheduled to arrive at 4 p.m. from Chicago was delayed and an American flight arriving at 5:15 p.m. from Dallas-Fort Worth was cancelled.  The American flights from Moline to Chicago at 4:30 p.m. and to Dallas-fort-Worth at 5:45 p.m. were also cancelled.

Initial reports indicated all American flights would be delayed until 5 p.m. Eastern time (4 p.m. Central time) Tuesday.

CNN reported American's reservation systems were restored by 4:30 p.m. but the company said passengers could expect delays and cancellations throughout the day.

The decision also resulted its regional affiliate, American Eagle, holding flights at Dallas Ft. Worth, Chicago's O'Hare and New York LaGuardia -- all major airports for the carrier's domestic operations.

The glitch caused big delays and flight cancellations for the company, which sought court approval on Monday to exit bankruptcy. It plans to merge with US Airways.
