If you take the word “free” and rip the “r” out of it, what do you get?Two things, actually: You get a “fee” — and then you get mad.This is happening to millions of airline passengers who are discovering that the advertised price of a ticket isn’t the half of it.Airlines have added beaucoup fees, charging us for items that previously were — and still should be — free. People’s rage-ometers zing into the red zone when they see that these fees-for-former-freebies will often more than double the cost of a trip.Like diabolical bankers did years ago, top executives of airline corporations have learned to goose up prices and profits — as well as their own pay — by nickel-and-diming customers. Only, their fees are way more than nickel and dimes.For example, say you schedule a flight, but something comes up and you have to change the time, day, or destination.
