Passengers looking to check in to WestJet flights — as well as other major U.S. airlines — are facing major delays as the companies saw technical difficulties on Tuesday morning.
Customers first noted the issue on Twitter around 11 a.m. ET.
In a statement to Global News, the issue was with the Sabre flight reservation system, which is also used by WestJet.
American Airlines also told TechCrunch the issue was with the Sabre system. Sabre is used by over 400 airlines as well as many hotel companies, TechCruch reports.
At 1 p.m. ET, a spokesperson from WestJet told Global News the system was back up and working.
On Twitter, the company said: “Our reservation system is temporarily down which is affecting our website. Rest assured our Digital Team is aware, and is working to have the situation fixed as soon as possible. We appreciate your patience and understanding.”
On Twitter, Sabre acknowledged there were issues and said the company was working to resolve the problems.
Customers on Twitter also said some systems in the airports were down as well.
There was no timeline for when systems would be back online.
