You're stuck. Maybe it's a long layover, maybe it's a flight cancellation, or a blizzard.

However it happened, you're stranded—for a few hours or longer—along with thousands of other people. Resources are limited, and you've got to act fast. Here's what to do.

Plan Your Escape

Contact the Airline: For the best chance of success, you'll want to multi-task. Stand in line at the airport while simultaneously calling your airline's customer service line (program the number into your phone before leaving on your trip). And if you're having trouble speaking to someone in person or over the phone, try the social media route. Many airlines use Twitter to address customer service issues.

Get a Room: If you and thousands of other people suddenly find yourself stranded, you'll need to book a room quickly unless you want to wait out an overnight delay in an airport chair. There are a number of last-minute booking apps, but when we travel, most of us use Hotel Tonight. Its discounted last-minute rates are great, and its app is user friendly.

Find a Day Trip: If you're stuck at an airport during the day, but can fly out before an overnight hotel stay becomes necessary, consider a day trip. A number of airports offer a list of day-trip itineraries for people with long layovers, trips that are easy to get to from the airport via public transportation. For instance, one of Japan's most popular temples is a short train ride from Tokyo Narita Airport. And from Frankfurt Airport, beer tasting in Bavaria is a quick trip. Many airports have bag checks (though some still haven't reinstituted them since 9/11), which allows you to stash your suitcase and travel light on a day out.

Make the Most of Being Stuck

Hunker Down: Airports are notoriously uncomfortable places to grab some shut eye, but when you've been awake for 20 or more hours, even a vinyl chair can look like bed. I've had success using the Guide to Sleeping at Airports to help me find the least uncomfortable options when I need to overnight at an airport.

Know Your Airport Amenities: As airlines cut down on basic amenities, many airports are increasing theirs, offering stranded passengers nearly pleasant ways to pass the time. Airports offer everything from yoga rooms to exercise bikes, and from napping pods to showers and spas.
