A buddy of mine is a controller at Spokane Intl. The first week that Southwest started serving GEG, he had a SWA jet ask him this:
"So what’s the secret word to use to get preferential treatment here?"
He didn't want to respond, but it only took a few seconds for someone to key up and say: UNITED
Don't know if it's still that way, but I thought it was funny when I heard it.
