Frontier vs Spirit: Which Budget Airline Is Actually Better for You?

When it comes to ultra-low-cost travel, the big question many flyers ask is which is better Frontier or Spirit? Both airlines are known for cheap base fares, but the experience can feel very different. Frontier Airlines often wins on newer aircraft, slightly better on-time performance, and family-friendly perks like Kids Fly Free promotions. Spirit Airlines, on the other hand, has a larger route network, more frequent flights on popular routes, and a clearer upgrade path with its Big Front Seat.

So, which is better Frontier or Spirit depends on your travel style. If you want the lowest possible fare and don’t mind paying extra for add-ons, either airline can work. Choose Frontier for cleaner planes and simple trips, or Spirit if you want more destinations and seat upgrade options while still keeping costs low.
