You know you're in trouble when the airline fees start getting metaphysical.

How else to explain Spirit Airlines' new $2 "Department of Transportation Unintended Consequences" fee? The airline is claiming that the DOT's new requirement that airlines allow passengers to cancel a ticket within 24 hours of booking with no penalty will lose them so much money (by forcing them to hold seats for people who may not end up buying them) that they need to charge everyone $2 more to make up for their losses.

Never mind the fact that Delta, and other more consumer-friendly carriers, have been extending this courtesy to travelers for years now, without whining about lost revenue.

"Unintended consequences" fee? I'd call it the "sore losers fee". Shame on you Spirit!
