This has undoubtedly been the year of the fee. We've seen so many airlines add first-checked-bag fees in particular that it's hardly controversial when another carrier jumps into the fray (as AirTran and Delta have done this month).
But with fees becoming so commonplace, what's next? Last week, United announced a discount on its first-checked bags when passengers prepay online. Will more airlines use their fees to fuel gimmicks and promos like this as they compete for your business? Are "fee sales" the next frontier for airline marketing? Do fee discounts make you any less unhappy about paying fees in the first place? Weigh in with your thoughts on the future of fees by leaving a comment below. Thanks!
