Customers across the U.S. reported airline computer issues at a number of airports.
A flood of tweets began to roll in a little after 11am ET (8am PT) about computer or network issues. Passengers on the ground said the issues related to the flight check-in systems being unable to issue boarding passes.
A spokesperson for American Airlines confirmed the issue was with the Sabre flight reservation and booking system, used by several major airlines — including WestJet, Alaska Airlines and JetBlue, all of which had passengers reporting issues.
The airline spokesperson told TechCrunch that the “brief technical issue” was resolved after 11:40am ET, and apologized to customers. JetBlue later confirmed it was recovering from the outage.
Sabre spokesperson Melissa Syphrett, echoing a tweet, said a nondescript “system issue” was to blame but declined to comment on what the issue was or what caused it.
Sabre is one of a handful of flight reservation systems used by airlines around the world. Sabre, developed by Texas-based Sabre Holdings, provides service to more than 400 airlines and 220,000 hotels. The company reported a significant data breach in mid-2017 affecting its hotel reservation system after hackers scraped millions of customer credit cards.
Updated with comment from JetBlue and Sabre, and that the outage has resolved.
