Opens in a new window Credit: Southwest $49 one-way Restrictions and exclusions apply If you’ve been dreaming of sandy beaches, a lakeside getaway, or a weekend trip to explore a new city, Southwest Airlines just announced its spring sale, where you can get one-way flights for as low as $49.
Of course, there’s some fine print to go over here: The discounted fares are only available for select routes and dates, so you'll need to be flexible with your travel plans. You’ll also need to book by March 13 to get the low prices, and your travel dates must fall between March 31 and June 11. Some blackout dates may also apply, so be sure to check the details carefully.
