Spring isn't officially over until all the best airfare deals have been scooped up. That means you can look forward to some sweet savings now that you've devoured everything in your Easter basket. Several airlines in the United States and Europe are running flash sales that offer steeply discounted airfare rates from now until the end of spring.

You can get to great cities and resort areas around the world if you act quickly to snag these deals before they melt away once the summer heat kicks in. Are you ready to hop over to a fun destination now that Easter is done and the weather is warmer? Here's a look at how you can book your airfare for just a few jelly beans.
