United Airlines will increase the fuel surcharge on roundtrip tickets to $50, a new industry high. “Every penny increase in a gallon of jet fuel costs our industry $195 million annually, and while we operate more efficiently, we must be able to pass commodity costs on to customers, as other industries do,” said UAL spokeswoman Robin Urbanski. The new surcharge is more than double the previous charge. Other airlines haven’t yet commented on whether they will match the move. Just another reason to not fly United.
