Until Sunday, travelers at the Gatwick Airport in London can get a free preflight spray tan. Dubbed the Gatwick Glow, the service is a result of research done by the airport which concluded that having an existing tan preholiday gives vacationers more confidence. "Gatwick Glow is designed to give our passengers a boost. We want them to head off on their holiday feeling great about themselves," the Gatwick Airport's Kim Francis told the Daily Mail. Perhaps the thought of a gooey cinnamon bun already gives you that warm glow, but would you consider getting your warm glow on by spray-tanning at the gate?
