Frontier Airlines is discounting fares again this week. Take 75% off nonstop domestic flights for travel this spring. Fares start at just $51 roundtrip. More days of the week are available than in the previous sale this week.

How to Book  / Travel Availability

Use promo code SAVE75 when booking on FlyFrontier.com to take 75% off the base fare for nonstop domestic flights on Mondays, Tuesdays, Wednesdays, and Thursdays, through April 17, 2019, with a 7-day advanced purchase required. Avoid blackout dates on March 21, 25, and 28.

Keep in mind that the discount does not apply to taxes nor Frontier's online booking fee, which is labeled a "Carrier Interface Charge". This means some routes still won't have a very big price drop even with the big sticker shock of 75% off. However, there are plenty of routes where we are seeing some big price drops for a last-minute spring break trip.

There are specific routes excluded from this promo code sale and you also may have to click around to find available dates since Frontier operates about half of its route network on just a few days each week.

Sale Period

Tickets must be booked by 11:59 pm ET, March 15, 2019.

Seat Assignments

Seats will be assigned at random upon check-in for these prices. You may pay a fee to choose a specific seat.

Alternate Fares

Frontier offers the Works bundle, which can be added to any flight during initial booking. It includes a standard carry-on bag plus a personal item, one free checked bag, seat selection (including stretch seating), priority boarding, flight flexibility, and refundability. This is a value if you want all of these amenities, but chances are you can get away with just adding what you need a la carte for cheaper.
