Snow covers Alaska Airlines plane
Heavy snow fell overnight at Sea-Tac Airport, causing 80+ cancellations.

If you’re traveling from Seattle-Tacoma International Airport or Portland International Airport this morning, chances are your flight is either canceled or significantly delayed.

A strong, overnight winter storm dumped 3-5 inches of snow on Sea-Tac Airport, blanketing planes and ground equipment. The wintry conditions have forced Alaska Airlines and Horizon Air to cancel 82 flights, affecting 10,000 passengers. Additionally dozens of flights inbound to Seattle have been canceled or are being held to prevent gridlock at Sea-Tac.

“The conditions are so severe a Sea-Tac that it’s taking our crews 30 to 40 minutes to deice a single plane,” said Wayne Newton, Alaska Airlines’ managing director of operations – Seattle. “If you don’t have to travel today, it’s a good day to stay home.”

What to do if you’re traveling from Sea-Tac:

  1. Check online to see if your flight is impacted, before heading to the airport. Additional flight cancellations are expected throughout the day.
  2. If you don’t have to travel today, consider changing your ticket. We’re waiving change fees and offering full refunds. Learn more here.
  3. Be safe. If your flight hasn’t been canceled, leave extra time to drive to the airport.

A winter storm is affecting operations in Seattle, Portland, Eugene and Redmond, Oregon. The National Weather Service forecasts snow and snow showers this evening through tomorrow morning. With snow accumulations between 2-3 inches anticipated, both airlines are thinning out their operations tonight and tomorrow morning to help ease congestion and allow deicing operations to run more efficiently.

Alaska and Horizon have canceled 60 flights in and out of the four airports scheduled to depart tonight and tomorrow morning. The 5,000 affected passengers have been notified and are being reaccomodated on later flights.

Passengers flying into the impacted airports may change their travel plans, without incurring a change fee, for tickets purchased on or before Feb. 4 or may request a refund. Learn more at
