A late summer or fall getaway just got cheaper to book. Frontier Airlines recently announced a ‘1 Million Seats’ fare sale with deals as low as $19 one-way. The sale extends to popular locations such as Atlanta, Dallas, Denver, Houston, Las Vegas, Orlando, and more. The sale pricing expires on June 13, 2024, and is valid on travel dates between now and June 15, 2024 and then again from August 19, 2024 through October 31, 2024, with some caveats. The airline will only allow discounted tickets to be purchased for flights on Mondays through Thursdays, and Saturdays. There are other restrictions for travel dates to Las Vegas, Florida, and international destinations, so travelers should carefully review the sale terms to ensure they are getting the best deals. The discounted fares of $19 are only available to members of Frontier's paid-subscription service Discount Den, which has a $59 annual membership fee and provides access to deals and other amenities for members. For those without the Discount Den subscription, the starting sale price is $29. Travel + Leisure spotted some of the deals include:
