Browse all current deals · How we verify · Affiliate disclosure
Frontier’s savings come from a few programs. Discount Den is a paid annual membership that auto-renews, showing member-only fares and including Kids Fly Free, where one child under 15 flies free per paying adult on eligible dates. Email promo codes typically take a percentage off base fare for set travel windows and must be used within a day or two. The GoWild! Pass offers all-you-can-fly travel booked close to departure. Frontier Miles and the Frontier credit card add miles and fee waivers. The guide explains bag, seat, and bundle fees.
