Will the closure of the Denver airport affect my travel out of SEATAC tomorrow, Dec. 22nd?
Several airlines with flights from SEATAC to ORD have a stopover in DEN tomorrow, and the Denver airport will not open until at least noon with time beyond that needed for clearing the airfields. You may run into issues with other travelers trying to get onto your flight and overbooking. Your best bet is to call your airline and find out what their seating policy is and how to avoid getting bumped, if you should check in early, etc. Good luck.
