The credit card charge I don't mind so much. Budget airlines are understandably concerned about margins, and the 1% they charge is lower than what I understand prevailing credit card handling commissions to be. (Assuming that there is a 1%-free debit card option, of course. If not, then that's just a 1% margin booster in the guise of something else.)
