DFW AIRPORT -- A computer glitch delayed flights Monday night at DFW airport and cancelled flights in the U.S. and overseas.

Four-hundred flights were impacted at 100 airports.

At DFW, a spokesperson said 10 incoming and three outgoing flights were delayed when the reservations system failed. The system is operated by Southlake-based Sabre, a company that hosts computer bookings for airlines across the globe.

The outage lasted for about two-and-a-half hours. It's unclear what caused the system to fail.

Rick Seany with Dallas-based said the outage was significant, but in similar situations travelers should act quickly to get the best and most-accurate information.

"The key is getting good quality information as quickly as you can; smart phones, calling in, if that's what you need to," he said. "Typically, there's not enough humans now to get good, quality information."

Seany also offered advice when you find yourself in a region with significant delays.

"You need to get to a location where there's not as many glitches," he said. "So, for example, if you are stuck in New York somewhere, and the only place you can fly to is Chicago or Minneapolis, that's where you want to go. What you don't want to do is be stuck in New York, along with the other [people] stuck in the region. Get out of that place. That way there's some empty middle seats to get you home."

During the most recent outage, airports on the West Coast and overseas were impacted most. Tuesday, were operations back up and running with few delays.
