Could these reveal last-minute deals worth packing for?

» Available for: iOS

» Cost: Free

» What they does: To use Flight Tonight, a simple iOS app from Hopper.com, you input your hometown airport code and it returns same-day flight deals — domestic and international — for that airport and nearby cities. Results vary throughout the day because of frequent updates. If you check later in the afternoon and evening, you’ll find deals that leave the next day.

» What’s hot: The app is for those who must make last-minute trips and for travelers who can be spontaneous and can usually spend a little more. Check the app earlier in the day if possible to get the broadest selection of flight and deal options. To get details on cheap flights between two destinations, see the "When to Fly and Buy" on the Hopper.com website. Also check the "Deals" section that features upcoming destination-specific deals from your hometown.

» What’s not: If you’re serious about being spontaneous, don’t rely solely on the app, but also search Hopper.com. It’s more work, but I found even better prices and more destination options on Hopper.com in my tests. The app also might specify a return flight that would keep you at your destination a certain number of days, but the website offers more flexibility, allowing you to search different days or exact dates.
