What do you do if your flight is cancelled?
SmarterTravel.com says your smart phone could be your best friend. It has listed five apps it says many airlines don't want you to use.
The first one comes from FlyersRights.org It tells you your legal rights if your plane is stuck on the tarmac, and helps you log the delays using GPS. The Flyer's Rights app is 99 cents. It is only available for iPhone.
Skyscanner is a free app that scans all the airlines and the online travel sites like Expedia to find you the lowest fare. You can search by date, destination or even how much money you want to spend. It is free on iTunes.
Number three is good for long layovers. It's Priority Pass, an app that searches for private lounges like the Sky Club and tells you how much it'll cost you to get in. It is free.
B4YouBoard allows you to order food delivered to the gate. So far it's available in Chicago, New York and Minneapolis but not Atlanta. It's free.
The last one is $2.99 but Smarter Travel says it could easily pay for itself. If your flight is delayed or cancelled, or you miss a connection NextFlight tells you the next available flights on all airlines, and finds hotels and rental cars.
