Travelers in the United States that base their vacations around cheap flights will have to hurry up and take advantage of Southwest Airlines' latest deal while available.

Up until midnight on Friday, the Airlines company is offering extremely cheap $39 one-way flights (h/t TravelPulse.com). If none of those $39 one-way trips intrigue you, then there are other flights available for as low as $49.

Southwest Airlines' official website outlines that "14-day advance purchase required for continental U.S. travel." The $39 flights include Kona to Honolulu, and from Oahu to Maui while Atlanta-to-Nashville flights are available for as low as $49.

Other extremely bargain flight deals include Los Angeles to Las Vegas for only $49 and Los Angeles to Chicago for $57 (in February), among others. You can check out the airlines' Low Fare Calendar here in order to search for certain deals.

The American Thanksgiving weekend in November, along with the holiday season in December, are among the most busiest and most expensive travel periods. But Southwest Airlines is giving travelers that prime opportunity to score the best possible flight deal now while they're available.
