Software firm's glitch stops travelers from booking tickets

A technology company says it's fixed a problem that had prevented travelers from booking trips with some U.S. airlines this week.

For a time on Monday night, customers of Southwest Airlines, JetBlue Airways and Virgin America were unable to buy new tickets or change existing reservations. The airlines tweeted that their systems were running again.

The airlines use technology from Sabre Corp., an American Airlines spinoff based in Southlake, Texas.

A Sabre spokeswoman said Tuesday that the problem occurred within a system that helps airlines determine seat availability and pricing.
