Frontier’s SAVE100 promotion is no longer available. The airline announced the offer on December 1, 2025, with a booking deadline of December 2, 2025, and eligible travel only through February 28, 2026. It discounted eligible base fares—not the full cost of a flight—and came with route, date, fare-class, and purchase restrictions.
What Frontier’s SAVE100 offer covered
Frontier described the Cyber Monday 2025 promotion as 100% off eligible base fares. To use it, customers had to book by 11:59 p.m. Eastern on December 2, 2025, on FlyFrontier.com and enter promo code SAVE100. Eligible travel was on Tuesdays, Wednesdays, and Saturdays through February 28, 2026, subject to blackout dates. Round-trip booking and purchase at least seven days before travel were required; route and fare-class exclusions also applied. Frontier’s December 1, 2025 announcement sets out the offer terms.
Does 100% off mean the flight was free?
No. The promotion applied to the eligible base-fare portion, not government taxes, fees, or carrier-imposed fees. The final amount due could therefore remain substantial, and the fare discount did not remove the offer’s eligibility restrictions or guarantee availability on a particular route or date.
Is the SAVE100 code still valid?
No. Its booking deadline passed on December 2, 2025, and the eligible travel window ended February 28, 2026. The cited offer is historical, not a current booking opportunity.

How the later 2026 Frontier promotion differed
Frontier’s May 7, 2026 announcement described separate offers for customers affected by Spirit’s shutdown. It included systemwide rescue fares of up to 50% off base fares when booked by May 15, 2026, as well as a temporary waiver of the $50 Discount Den enrollment fee from May 6 through May 15. Those deadlines have also passed; this later announcement does not establish that SAVE100 or another 100%-off offer is available. Frontier’s special-offers page is the airline’s destination for promotion information, but the cited announcement—not a current offer—is the basis for those historical terms.
