Southwest Airlines is having a nationwide sale on flights with one-way tickets starting as low as $39 and round-trip tickets from $98. This is one of the most affordable ways this year to get across the U.S. and to your destination quickly, and at these prices, you could even consider just going for a short one or two-day trip. There's just one catch: the sale comes to an end at midnight EST tonight. That doesn't leave you much time to figure out where and when you're flying, so you should start making plans ASAP.

You'll also want to keep in mind Southwest's baggage fees. Your ticket allows for a carry-on bag, a personal item, and two free checked bags up to 50 pounds each.
