Fly Across the Country for Less Than $30 With Frontier’s 30th Birthday Sale — but You Have to Book Soon

Frontier Airlines is turning 30, and celebrating the milestone birthday with a big sale that has flights under $30 on 100 of the airline’s routes.

The sale must be booked by 11:59 p.m. ET on June 27 and is valid for $29 one-way flights through Nov. 13, according to the airline. The promotional fares are available for nonstop travel on Mondays through Thursdays and on Saturdays.

“We want to thank our customers for their loyalty as we celebrate our 30th birthday this year and what better way to do so than by offering amazing fares to so many incredible destinations,” Tyri Squyres, the vice president of marketing at Frontier Airlines, said in a statement. 

Travel popular routes across Frontier’s network like Atlanta to Chicago, Nashville to Philadelphia, Baltimore to Tampa, Cincinnati to New York City, Denver to Los Angeles, and more starting at just $29 one-way. Or island hop in the Caribbean — where the airline has been expanding — with $29 one-way flights from San Juan, Puerto Rico, to St. Croix in the U.S. Virgin Islands.

Like most sales, there are a few catches. Not all destinations are available on all days (and some have specific days you can travel), and several blackout dates also apply: on July 3, from July 5 to 7, on Aug. 29, from Sep. 2 to 3, on Oct. 10, from Oct. 14 to 15, on Nov. 7, and from Nov. 11 to 12. A seven day advance purchase is required, but travelers do not need to purchase a roundtrip ticket to take advantage of the sale. 

Frontier is an ultra-low cost airline and charges passengers for everything from seat assignments to baggage. However, the airline recently started offering more luxury options, including introducing a new economic business class, called BizFare, and adding an “UpFront Plus” option, which allows travelers to purchase seats in the first two rows with a blocked middle seat for added comfort.
