>From yesterday's Arizona Republic. Gnome for the holiday With a mother who works for Southwest Airlines, it's not surprising that Owen Eichinger's first Halloween costume has a travel theme. But the son of spokeswoman Whitney Eichinger is not going to be a bag of peanuts, a blue-and-red plane, or even an assigned seat. The little munchkin is going as the Travelocity gnome, the online travel agency's bearded mascot with the red cone hat. His grandmother made the costume. Southwest watchers will note the irony: The airline doesn't sell tickets on Travelocity, or any other online agency.
