Southwest winter flash sale: Get one-way flights for as low as $29

If you have family members you want to visit or you’ve just been itching to take time off for a short winter trip, then book your flights with this Southwest deal. The airline is having a three-day winter flash sale where one-way fares start as low as $29.

Up until Oct. 6., Wanna Get Away fares are available for many cities in the continental U.S., along with routes to Hawaii, Puerto Rico and some international destinations.

The deal extends to travel that takes place from Nov. 19 to Feb. 15. However, the deal doesn’t apply to flights from Dec. 16 to Jan. 9, so you won’t have much luck booking cheap Christmas and New Year’s travel.

Also, there are certain travel restrictions in this deal. For example, these low fares do not apply to continental U.S. travel on Fridays and Sundays. Additionally, low fares for travel to international destinations are only valid from Sundays to Wednesdays; the same discounts only apply to travel from international destinations from Tuesdays to Fridays.

While many routes primarily in Southwest’s network qualify for discounts under this deal, we found that certain routes — like New York to Boston, for example — are not included in this deal.

Since this deal will only last for two more days, we recommend booking your tickets as quickly as possible. The seats on these flights could fill up quickly with such low prices.

Looking through calendar dates for flights between Baltimore and Boston, the majority of days in January after the blackout dates are priced at $29; only flights taking off on Fridays and Sundays cost more at $79.

Bottom line

After searching through some of the routes in this Southwest deal, we found that the majority of low Wanna Get Away fares are still available. However, the lowest fares are mostly available from December to the beginning of February. Southwest’s Low Fare Calendar doesn’t have as much availability in November. There are also blackout dates around Christmas.

Given how some of these fares have been significantly discounted, flights are certain to fill up the longer you wait to book your flights. So, make sure to buy your tickets as soon as you can.
