Alaska Airlines has grounded all flights across the United States due to an IT issue.
'Alaska Airlines is experiencing an IT outage affecting operations. A temporary ground stop is in place,' the airline said in a statement.
'We apologize for the inconvenience.
'If you're scheduled to fly tonight, please check your flight status before heading to the airport.'
The flights were grounded because of an unspecified tech-related issue, according to a Federal Aviation Administration advisory.
Alaska Airlines posted an alert on its website, saying: 'Looks like we are experiencing a temporary technical issue.
'We are aware of the issue and are actively looking into it.'
The outage also grounded Alaska Airlines's subsidiary Horizon Air.
Social media users shared how the ground stop was impacting their travel plans.
One X user wrote: 'Sitting in a full plane on the tarmac at [Seattle-Tacoma International Airport]…for the past 45minutes…'
Another posted: 'Sittin' in aircraft supposedly departing to [Seattle] at [Tucson] for about 45 min now.'
In July, Alaska Airlines also grounded its flights for three hours due to a 'significant IT outage.'
The issue affected the travel plans of 15,600 people, the airline said.
This is a breaking news story. More to come.
