I think that I've not yet encountered an airline that has lived up to their end of the bargain enough over time to worry me about the moral relativism of the situation. Likewise, I don't have trouble sleeping at night when I purchase a mistake airfare or get in on a churn n burn loophole scheme a la pudding cups/ gift cards/coins/anything points/etc. I see it as evening the ledger. Take it or leave it. I can't believe I'm indulging someone's holier-than-thou schtick on an anonymous internet message board.

peace,
