[Expired] Frontier’s Cyber Monday Sale Offers 100% off Base Fares — With Key Restrictions To Know

Today is Cyber Monday, and Frontier Airlines is marking the day with another strong promotion — one that wipes out base fares entirely. The ultra-low-cost carrier is offering 100% off base fares when travelers use promo code SAVE100 directly with the carrier.

The sale runs now through December 2, with valid travel dates through February 28, 2026, on select days and routes. However, some popular city pairs — including several to and from Orlando, Miami, and Denver — are excluded from the deal.

Here are the specifics of this sale.

Frontier’s SAVE100 Promo: What Travelers Need To Know

Frontier Airlines is back with another worthwhile sale — and this time it’s for Cyber Monday. The carrier’s latest promotion runs through tomorrow, December 2, offering savings on winter travel dates through February 28, 2026.

The deal wipes out the base fare portion of your ticket, though you’ll still pay taxes, government fees, and carrier-imposed charges.

To take advantage of this offer, you’ll need to book by December 2 at 11:59 p.m. ET and travel on Tuesdays, Wednesdays, or Saturdays, using the promo code SAVE100.

A 7-day advance purchase and round-trip booking are required. The offer applies to both domestic and international routes, including nonstop and connecting flights.

However, there are caveats to be aware of. Several blackout periods apply, including December 18–31, 2025; January 1–5; January 16–19; and February 13–16, 2026. Frontier has also excluded several popular city pairs from the promotion, such as Boston (BOS)–Orlando (MCO), Cleveland (CLE)–Miami (MIA), Denver (DEN)–Orlando (MCO), Orlando (MCO)–Chicago (ORD), Orlando (MCO)–Philadelphia (PHL), Houston (IAH)–San Pedro Sula, Honduras (SAP), and more. That means travelers on these routes won’t see the discount applied.

Frontier says the promotion ties into its broader push to upgrade the flying experience as part of “The New Frontier,” which includes new first-class seats scheduled to arrive in 2026.

Frontier Adds a GoWild Pass Bonus for Cyber Monday

Frontier is also sweetening Cyber Monday with a small bonus for its GoWild passholders. Travelers who purchase a GoWild 26–27 Annual Pass between now and December 2, 2025, at 11:59 p.m. MT will earn an extra 4,000 Frontier Miles.

The bonus miles can be used toward award flights or bag and seat bundles, and they’ll be deposited into the Frontier Miles account used to purchase the pass. The offer is limited to 1 bonus per member.

Final Thoughts

Frontier’s Cyber Monday promo is a solid opportunity for travelers who can fly midweek or on Saturdays and work around the blackout dates and route exclusions. While add-on fees still apply, eliminating the base fare can result in significant savings — especially on longer routes.

If the timing and routes line up with your plans, it’s worth pricing out a trip by tomorrow, December 2, to see how much you can save.
