How to deal with delayed or canceled flights

It's happened at least once to most of us: We arrive at the airport, family members and luggage in tow, only to find out that our flight has been delayed for hours or canceled altogether.

What should we do?

George Hobica, a veteran travel journalist - he used to write for the Daily Herald - and founder of the consumer Web site airfarewatchdog.com, offers these tips to travelers heading out of town for the Fourth of July weekend:

• If your flight is delayed or canceled, stand in line but get on your cell phone immediately to start making arrangements; don't wait until you reach the ticket agent. Hobica suggests looking for a flight on a competing airline. While not obligated to do so, many airlines will assist passengers with this when faced with a crisis, like United's computer glitch Thursday morning at O'Hare, Hobica said.

• If the delay renders your trip pointless - you'll miss the wedding you were going to, for example, or an important business appointment - stay in town and ask the airline for your money back. Airlines generally have to do this, even if the ticket is labeled "nonrefundable," Hobica said.

• When planning the trip, avoid connecting flights, even if that means spending more. It's much easier to deal with delays if you don't have another plane to catch.

• Try to book the first flight of the day. These tend to be the most problem-free.
