Alaska Airlines flights resume after FAA's temporary ground stop

The Federal Aviation Administration (FAA) on Wednesday lifted a temporary nationwide ground stop advisory for all Alaska Airlines flights.

The FAA said in a statement that "operations are normal" after Alaska Airlines asked the agency to pause departures nationwide as it worked to resolve an issue with its weight and balance system "as quickly as possible." 

Alaska said it's already begun releasing flights and that "residual delays" are expected throughout Wednesday.

The ground stop was issued around 7:30 a.m. PT for all Alaska and Horizon flights. The "issue was mitigated and the ground stop for Alaska and Horizon flights expired" an hour later, Alaska said.

SkyWest flights were excluded from the advisory. SkyWest and Horizon Air are both regional carriers. 

"This morning we experienced an issue while performing an upgrade to the system that calculates our weight and balance," Alaska said in a statement.
