What's the story

Alaska Airlines has implemented a grounding order for its entire fleet of 325 aircraft due to an IT outage. The decision was confirmed by a Federal Aviation Administration (FAA) notice issued on Sunday evening (local time). The grounding order also extends to Horizon Air flights, a regional subsidiary of Alaska Airlines. Passengers have been advised to check their flight status for any potential delays or cancellations.

FAA's notice does not explain reason for grounding order

The FAA's notice, issued shortly after 9pm (local time) on Sunday, does not explain the reason behind the grounding order. It affects all planes operating under Alaska Airlines' main brand and includes those operated by Horizon Air. The Alaska Air Group has a fleet of 238 Boeing 737s and 87 Embraer 175s, according to its website.

Passenger impact

Thousands of passengers stranded at Seattle airport

The sudden grounding order has left thousands of passengers stranded, particularly at Seattle-Tacoma International Airport, the airline's main hub. Social media posts show crowded waiting areas and frustrated travelers. One user even suggested a hilarious solution for the IT issue, tweeting, "Hey @AlaskaAir we're stuck on the tarmac in #Seattle. The pilot said all Alaska systems are down for the next hour. Can someone in IT just unplug the computer, wait 5 seconds, and plug it back in?"

Last major issue was reported in 2022
