You're charging me for what?! Airline fees way up in 2008

Since January 1, passengers have been treated to a nonstop roller coaster ride of airline bankruptcies and mergers, fuel surcharges, and imaginative new ways of charging for "perks" that were once free. The devil is in the details, however, and knowing which airlines have added new fees can go a long way in helping you compare apples to apples in your airfare search.

Here's a rundown of the new fees assessed by each airline since the calendar turned to 2008. (Most of these fees affect domestic travel. International fees may vary.)
