Flight Delayed or Cancelled at Seattle-Tacoma International Airport (SEA)?
Seattle-Tacoma International Airport (SEA) is Alaska Airlines' largest hub and a Delta hub for flights to Asia. Low clouds and rain are common, and the occasional snow or ice event can hit hard.
Airlines and terminals
Alaska and Delta carry most SEA passengers. United, American, Southwest, JetBlue, Frontier, and international airlines also fly there.
SEA has one main terminal with Concourses A through D, plus North and South satellites reached by underground trains.
Your options depend on the airline operating or selling your ticket. Airline guides: Alaska, Delta, United.
Common causes of delays at SEA
- Low clouds and reduced visibility
- Occasional snow and ice that the region rarely prepares for
- Wildfire smoke in late summer
Crew and many maintenance problems are generally within the airline's control; weather is not. See our weather delay guide.
The DOT refund rule
Under the US DOT refund rule (14 CFR Part 260), if your SEA flight is cancelled or significantly changed and you turn down the changed flight, the rebooking, and any voucher or credit, the airline has to refund your fare, taxes, and unused paid extras to the card or method you paid with. The cause doesn't matter.
A significant change includes departing 3+ hours earlier or arriving 3+ hours later than scheduled on a domestic trip (6+ hours international), a different airport, extra connections, or a cabin downgrade. Refunds are due within 7 business days for credit cards and 20 calendar days for other payment types. Accepting the rebooked flight or a credit generally ends the refund right.
Meals, hotels, and rebooking
On the DOT Airline Customer Service Dashboard, large US airlines commit to free rebooking and a meal or meal voucher for 3+ hour waits when the disruption is within their control. All except Frontier also commit to a hotel and ride for overnight disruptions. Weather and air traffic control usually fall outside these commitments.
A local tip for SEA
When snow hits Seattle, de-icing capacity can become the bottleneck. If your flight is cancelled, compare rebooking with a refund before you accept anything.
What to do
- Note the original and new times, and the reason given.
- Don't tap accept on a new flight or credit until you've decided.
- Ask about meal and hotel vouchers for controllable delays.
- Save receipts for anything you pay yourself.
- Send a clear, dated letter to the airline.
