Alaska Airlines made this announcement on November 30:
Additional snow hit the Seattle area on Wednesday afternoon/night. While Tuesday was challenging for many guests, who experienced long taxi times and deicing delays, our strategy of proactively thinning our flight schedule worked to mitigate the worst impacts from the storm. We’re implementing a similar strategy for this next snowfall.
Guests whose flights are pre-canceled will be contacted and reaccommodated on another flight. A flexible travel policy remains in place for guests to be able to adjust their flights themselves. Please use the Alaska Airlines app or visit alaskaair.com for more information.
We’re also enacting travel restrictions on flights to and from Seattle. Restrictions are now in place for animals in the cargo hold (AVIH) and unaccompanied minors (UMs) to protect the safety of everyone. Employees across our system are working hard to care for each and every guest and get you where you need to go. Guests traveling through Seattle should expect delays and extended taxi times. Thank you for your patience as we navigate these conditions together.
