Southwest is having a huge fare sale, with cheap flights starting at $49.

The cheapest flights are available on dozens of routes, like Atlanta to Orlando, Baltimore to Boston, San Francisco to Los Angeles or San Diego, and from Nashville to Pensacola.

And the deals aren't just for summer; travelers can book by May 18 for travel from June 5 through October 31. Most of the cheapest flights are on Tuesdays and Wednesdays. See the full list of sale fares.

While Southwest is often considering a low fare airline, it's not the typical budget airline like those that have recently expanded (like WOW Air and Norwegian). There are no extra fees for things like baggage.

Anyone not familiar should be aware that Southwest does not have pre-assigned seating. Instead, passengers receive a spot in line (in A, B, and C groups) and then board the plane, taking any available seat they prefer. To get a better seat, Southwest does sell priority boarding.
