The sale is valid for departures from November 30, 2016 through March 2, 2017 with some restrictions in December and January. Since Southwest uses a fare-based award redemption system, award tickets are also heavily discounted and could be a great use of Rapid Rewards points.You’ll have to search on Southwest’s website to find your ideal flight, as the airline doesn’t allow travel search engines access to their flight schedule. If you have the Southwest Companion Pass (now much easier to get thanks to the merger of Starwood and Marriott), this sale would be a great way to travel with a companion for next to nothing.Airline: SouthwestRoute: US and international routesCost: $44+ one-way in economyDates: November 30, 2016 - March 2, 2017Booking Link: SouthwestPay With: Chase Sapphire Reserve, Premier Rewards Gold Card from American Express, Citi Prestige Card or Chase Sapphire PreferredHere are a few examples of what you can book:Denver (DEN) to Los Angeles (LAX) for $44 one-way in January:Denver (DEN) to Los Angeles (LAX) for $44 one-way.Denver (DEN) to Los Angeles (LAX) for 2,002 points + $5.60 one-way in January:New York (LGA) to Chicago (MDW) for $49 one-way in December:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
