Southwest's Huge Flight Sale Still Won't Help You Save on a Summer Getaway

Plane tickets for under $100? Southwest unveiled a 72-hour long sale on Wednesday that will allow customers to snatch up seats on domestic flights for slashed prices — but the sale won’t help anyone looking to book a summer vacation.
The sale, which ends on Thursday at 11:59 p.m., only applies to trips booked for travel between August 25 through December 16. But flights for Labor Day and Thanksgiving — two of the busiest travel periods of the year and key revenue days for airlines — are conveniently excluded.
