In 2009, taxes added almost 17% to a ticket price, according to a Massachusetts Institute of Technology report issued in January. That's not surprising when you consider such pesky add-ons such as passenger facility charges (as much as $18, depending on where you're going), federal segment fees ($3.20 for each U.S. flight segment), a Sept. 11 security fee ($2.50 for each flight segment) and fees for non-U.S. destinations (as much as $200). What? Those sound like taxes and not fees? You can call them whatever you want, but they still add up, and you can't do anything about them, much like the only other thing that's certain in life. Foreign governments consider passengers good sources of revenue too, so they have joined in the levying fun over the years. Anyone buying airfare these days also usually has other fees — what I call the "convenience fees" — to contend with: baggage fees, priority boarding fees, change fees, fees for making a reservation by phone, fees for booking online, fees for extra legroom and on and on. You need a scorecard to track them. That's because, by and large, booking sites — whether an online travel agency, a metasearch site such as Kayak or an airline's own site — don't always do a good job of showing you the bottom line. That is being charitable, but for now, we won't come right out and call them duplicitous dirtbags. That (lack of transparency, not the dirtbagginess) will change in the coming months and may change even more, said Charlie Leocha, director of the Consumer Travel Alliance, a nonprofit consumer advocacy group in Washington, D.C.
