I think we all need to cancel our flights in and out of Seattle. (And let the airport management -- not the airlines -- know why.) Although contacting all the airlines might not be suc a bad idea. They will put pressure on Seattle.
(Nah! Just fly out of Spokane or Portland instead.)
Make them pay for their supidity.
Nah, I'm not going to punish Alaska Airlines because the Port of Seattle called the rabbi's bluff.
I'm flying home to Sea-Tac on Friday, and if I see a comment box anywhere I'll make it known that I'm disappointed in their decision.
