Southwest is having its first sale of the year: Up to 30% off flights between Jan. and May
SAVE UP TO 30%: Through Jan. 8, Southwest promo code DREAMBIG saves you up to 30% on select Southwest one-way or roundtrip flights between Jan. 26 and May 13.
Sure, you can start tackling health or organization-related New Year's resolutions pretty immediately. But who says you can't start chipping away at travel goals right away? Through Jan. 8, Southwest's first sale of the year saves you up to 30% on select flights within the continental U.S., as soon as Jan. 26 or as late as May 13. You must purchase your tickets 21 days in advance, so get planning.
To enact the discount, just enter code DREAMBIG, plug in your departure info, and look for the green fares replacing a price with a strike-through. The promo code does work on (qualifying) one-way or roundtrip Basic and Choice fares, but Fridays, Saturdays, and Sundays are barred from the sale.
Yes, you'll have to pay for bags now — Southwest ended its free bag policy back in May 2025. Think of the money you're saving on your discounted flight as your baggage fees.
