I am continuously amazed at how ticked off people get about baggage fees, yet they want to keep having $140 RT flights. Clowns on the news do their best to fan this fire whenever they report these stories.
Next time you are on a super leisure fare and get annoyed at paying $25 to check in your bag...remember this - the airline is losing money on you. Although you are paying $25, you are still screwing the airline. Hopefully that makes you feel better.
