Today ( Saturday, June 6, 2009)  if you’re flying to or through Seattle-Tacoma (SEA), Portland (PDX), and Spokane (GEG) airports,  go over to the Southwest Airlines gates and ticket counters and see if you can get it on their party.

The airline is celebrating 15 years of service to these airports with history and trivia “gate games” that give customers the chance to win prizes, including free tickets.

Maybe there’ll be cake.
