Airfares will soar this summer due to increasing fuel prices

Yet another airline fee is on the horizon, just in time for the busy summer travel season.

Fuel surcharges are likely to push airfares higher to make up for a 25% increase in airline gas prices so far this year, industry watchers warn.

"Airlines have gotten pretty good about adding fees on everything from aisle seats to extra checked baggage," said John Armbrust, president of Armbrust Aviation, which publishes the World Jet Fuel Report. "So the likelihood of them adding a fuel surcharge is pretty certain, I think, in a high fuel environment."
