How To Deal With Common Air Travel Snafus...

...and how to beat them! Part 4 of 8 in a series.

YOU'RE BUMPED FROM A FLIGHT

Last year, airlines bumped 681,105 passengers from flights in this country (8.7 percent of these individuals were bumped against their will). Overbooking is to blame.

Why it matters: If you volunteer to give up your seat, you'll be rebooked and usually rewarded with a free flight pass to use at another time. But if you're unlucky enough to be kicked off a domestic flight against your will, you're at the mercy of the airline's schedule. With planes often flying at capacity today, it could be a long while before you reach your destination.

How to deal: If you're bumped involuntarily, know your legal rights: Being placed on another flight within an hour scores you no compensation. Yet when it takes up to two hours on a domestic flight (or four hours for international travel), the airline must pay you double the value of your one-way fare, up to a maximum of $650. If you're more than two hours delayed, you'll be reimbursed four times the value of your one-way ticket, up to $1,300 max. Flying in Europe? Rules are similar, with possible compensation up to $874.

Trick for avoiding the problem: Check in via the airline's website as soon as you're allowed—usually 24 hours before departure. Early check-in may boost the chance that you'll make it onto a flight. Insider tip: When it comes to reimbursement, federal law entitles you to cash for being bumped against your will. The airline may try to give you a voucher for a free future flight instead. Insist on the cash, which is obviously less restrictive than a voucher. But if you're volunteering to give up your seat, don't be pushy about receiving cash. In that case, airlines aren't required to give you anything, so a gracious "thank you" is all that's called for.
