How crazy have airline baggage fees gotten? Well, checking an overweight (that's a 71- to 100-pound) bag will now cost you a whopping $400 on most Continental Airlines international flights. And Continental isn’t alone either, according to a survey of major carriers by USA Today; United Airlines also charges $400 for such a bag on any flights to other continents, and American Airlines charges $450 if that bag is headed to Asia.
Even checking your first standard-size bag is getting expensive, with some airlines charging as much as $43. Sprint Airlines even charges for carry-on bags, to the tune of $30 to $40 each. Other fees abound as well; Delta Air Lines and United charge $250 to change an international ticket, for example. Even supposedly "free" frequent-flier tickets now often come with booking fees; flying US Airways for free will cost you up to $90. (Read more airline fees stories.)
