Come on, you knew a $4 flight was too good to be true. No, you can't actually pay as little as the price of a certain low-cost Trader Joe's wine and fly wherever you wish at the snap of your fingers (or click of your keyboard). But — and this is a good "but" — if you act fast, you can fly to France and Norway for £2.99 (that's about $3.75) on Ryanair, with certain restrictions. And it's a flash sale, so hurry!
Here's the catch (and you knew there was going to be one): These cheap flights only depart from London's Stansted airport, which is about an hour outside of the city. Plus, you have to be pretty flexible with your dates. For example, Travel + Leisure reports, the £2.99 trip to Dinard is only available on April 4.
But if you're hopping around Europe anyway, and your dates aren't set in stone, this could be just the right deal to keep you exploring — and save some major moola while you're at it.
