No question, last-minute travelers can grab great deals. When hotels, resorts, cruise lines and even airlines have unused inventory, they often offer it at deep discounts — sometimes as much as 50 percent and more off original prices.

To be a successful “flash traveler,” though, you’ve got to be the kind of person who can toss things into a suitcase, lock the door and hit the road on short notice, (which excludes most parents of young kids and pet owners). Keeping your passport up-to-date doesn’t hurt either.

The biggest challenge, beside having enough clean underwear and socks on hand, is finding the bargains in time to book them before they disappear.

Luckily, there’s an app for that. In fact, there are a number of apps for last-minute travel. Here’s a few suggestions:

Flight Tonight: Tired of going through fare comparison sites looking for discounted flights from your local airport? This app does it for you and offers up a changing mix of same-day options for round-trip flights to U.S. and international locales. You can buy your ticket through the app.

Hotel Tonight: This app offers last-minute deals on hotel rooms in major cities, and discounts run as much as 70 percent. It's a great resource for anyone who gets stuck mid-route and for anyone who leaves travel arrangements until the last minute in order to get the best deals.

For Less: Once you arrive at your destination, you can save money on your meals and entertainment with the "For Less" apps. Editions, including New York City, London, San Francisco, Paris and Amsterdam, feature a variety of maps and ratings, along with discounts on attractions and restaurants.

LMT (Last Minute Travel): This app offers savings of as much as 60 percent on hotels, flights, car rentals, tourist destinations and sporting events in 4,500 cities worldwide.

Hipmunk: This app searches for the lowest airfare prices and lists last-minute hotel rooms that are as much as 60 percent off.
