Airline Fees On the Rise (Again)

We're beginning to sound like a broken record. It was just in May that we last examined the extra fees increasingly imposed by airlines, and they are at it again. New fees, part of a practice dubbed "unbundling," include peak travel surcharges, fees for standby, early boarding, and seat assignment, many sneakily hidden in the overall fare. The Department of Transportation estimated that now airlines present passengers with more than 100 additional fee options. So what do you need to know before you book?
