Funny you should mention that, I have a cousin whose last name is Lax, living in the San Fernando Valley. There is a (likely apocryphal) family story that one time when he showed up at the airport, his ticket had been converted into an order to ship 150lbs worth of freight.

Back to the thread.... Going slightly beyond the posted suggestion, but in honor of the nearby NSA HQ, I would change BWI into SPY. My personal airport would, of course, be named SOB. (Will that get converted into asterisks?)
