A friend of mine was on a business trip yesterday and trying to get home. His flight was bumped countless times and then canceled altogether. Arghhh.. In his case, it was weather related, understandable but frustrating just the same.
Here's a suggestion to not only give you something to do while you're waiting (because, c'mon - I know you're just playing around on your smart phone anyway) and actually help yourself get a leg up in the competition for a seat on the next available flight. Sign up for the airline's e-mail or text alerts. Passengers who get those alerts sometimes find out about cancellations even before they're announced at the airport, allowing them to get in line faster to talk to an agent. When you find out your flight is canceled, get in line and call the airline's reservations number at the same time. Someone may pick up the phone faster than it takes for you get to the front of the line.
