AirlinesTravel
Frontier Airlines is a U.S. ultra-low-cost carrier with a heavy hub presence in Denver. Base fares are very low and almost everything else (bags, seats, carry-on) is à la carte. Tickets code as airfare on every card we track. Frontier offers a co-branded Mastercard but no widely-recommended option, so general travel cards are the standard pairing — and the small fares mean trip-protection benefits rarely move the needle.
