St. Louis (KSDK) -- More than 42 million Americans will be traveling this Thanksgiving. The last thing you want to see at the airport is cancelled or delayed.
If you are do run into trouble, remember, you have rights as a traveler. First off, find out if the delay is because of weather or something else.
If a flight is canceled or delayed and it's a mechanical problem, the passenger has the right to receive hotel vouchers, taxi vouchers, and food vouchers. If your flight is oversold and you're bumped from a flight, know that you are due cold hard cash -- either $400 or $800.
If you used a credit card to book your travel, it can help.
If you don't get the service offered or if you do not get the compensation that you're due, challenge it with your credit card company and they'll fight the fight for you.
You also have rights if you get to your destination, but your bags don't. If your baggage is lost, you're able to get compensation up to $3,000.
If weather cancels or delays your flight, it's out of everyone's control. But don't give up.
If you have a problem with your flight, get up and get over to the customer service desk.
You do need to be persistent to make these things happen.
Here are a couple apps that will help take the edge off your holiday travel time.
Tripit: When you're traveling, you have to keep track of a lot of information, things like ticket numbers and confirmation numbers and your hotel confirmation number. TripIt keeps track of all of that stuff for you in a nice little itinerary that you can look at at any time.
TSAWait: This app tells you the wait time at every airport in the country. The data is updated every morning. They represent averages for recent activity, and as such they cannot perfectly predict future security delays. In particular, holidays, regional events, staffing changes, and weather disruptions can greatly impact normal activities.
GateGuru will give you the terminal map and a list of what is around you. GateGuru includes over 11,000 reviews from fellow travelers on airport amenities. The GateGuru community has also added over 3,000 pictures of airport amenities.
Flight Status gives you real-time flight information. It provides you with information about delays, cancellations, arrival times, even baggage claim numbers. And it's easy to use!
