Summer's not over yet, but it is winding down. That means it's time to start planning for how you're going to transform fall into Summer Part 2. The best way to do that is to make sure you have some trips planned -- preferably to warm places. Conveniently, Southwest Airlines is throwing a seriously huge sale with discounted flights from all over the United States this fall (and well into winter), so you can start planning that extended summer right now.
The sale runs through August 16, and you'll be able to find one-way flights for as low as $47. Keep in mind that Southwest isn't a budget airline, so that price will even include things like luggage and access to oxygen. While you won't be getting a round-trip fare for under $50, you should be able to find a round-trip deal for around $100 if you play your cards right. And again, this sale is seriously huge, with domestic and international flights, and it's you should be able to find fodder for a spontaneous trip no matter where you are in the country.
