Southwest Airlines is currently offering a generous 30% discount on select summer and fall flights, but act fast as the sale ends at 11:59 p.m. PT on Thursday.
To take advantage of this offer, use promo code SUMMER30 when booking new tickets to receive up to 30% off the base fare on Wanna Get Away and Wanna Get Away Plus fares for various travel dates.

However, make sure to carefully review the terms and conditions as there are certain restrictions in place.
The sale is applicable to flights operating on specific days:
While the promotion excludes certain flights, it is valid for flights from the continental U.S. to Hawaii and international destinations on Sundays, Mondays, Tuesdays, and Wednesdays.
For flights from Hawaii and international origins to the continental U.S., the discount is applicable on flights operating on Tuesdays, Wednesdays, Thursdays, and Fridays.
Travelers on interisland Hawaii flights can enjoy the deal on Tuesdays and Wednesdays, while those flying to and from San Juan, Puerto Rico, can benefit from the sale on Mondays, Tuesdays, Wednesdays, and Thursdays.
It's important to note that availability may be limited, as stated in the fine print, with certain restrictions based on destination, flight, and day of the week.
To determine if your flight qualifies for the discount, enter the promo code before initiating your flight search.
Southwest's website explains, "If you have entered the promotion code SUMMER30 in the Promo Code box on Southwest.com or swabiz.com during the Booking Period, then while selecting your flights, savings in the base fare will be visible as a strike-through of the original fare on eligible flights."
