Alaska Airlines requested a ground stop for its entire fleet of planes that operate under its brand name, the Federal Aviation Administration said in an advisory on Sunday night.

The reason for the advisory, issued just after 9 p.m. on Sunday, was not immediately clear. The grounding affects more than 200 planes under the Alaska Airlines brand but does not affect aircraft operated by the airline’s subsidiaries. As of April 24, Alaska Airlines said it operated 238 planes, all Boeings, under its brand.

Neither Alaska Airlines nor the F.A.A responded immediately to requests for comment.

Something about the weight and consequent thrust adjustment not working right.
Just speculation at this point.
For some reason, plane weight loads are not accurately measured (because doing so would cost more money?)

Probably based on a 2023 issue involving weight and balance. Long Hacker News discussion.

Alaska Airlines is requesting a ground stop for its entire fleet because of an IT outage...
We requested a temporary, system-wide ground stop for Alaska and Horizon Air flights until the issue is resolved," the statement said, adding that there would be "residual impacts" to the airlines' operations throughout the evening.

It did not respond to BI's query about how many flights would be affected or whether any ongoing flights were interrupted.

Per its website, Alaska Airlines has a fleet of 238 Boeing 737 aircraft and 87 Embraer 175 aircraft.
