Best Frontier Airlines Alternatives in 2026

By App Store Tracker Editorial · Updated — App Store ratings fetched to

The short version

The Frontier app handles booking, check-in, boarding passes, and trip management for the budget carrier, though reviewers cite glitches and harsh fees. The closest peer is Spirit Airlines, another ultra-low-cost carrier with the same add-a-bag-and-seat model and similar fee complaints. For more reliable service, Southwest and United offer fuller apps. Breeze and Sun Country round out the budget options. Pick based on which airline flies your route and the fees you accept.

People look for Frontier app alternatives when glitches block their boarding pass, when fees pile up, or when they want another airline on their route. Every pick below shares the core: an airline app for booking flights, checking in, getting a mobile boarding pass, and managing trips. Several are ultra-low-cost carriers like Frontier, others are larger airlines or flight-search tools. We ranked them by embedding similarity to the Frontier app, then weighed live App Store ratings and review counts so the more trusted, widely used apps surface first. These apps tie to specific airlines, so pick the one flying where you need to go and weigh its fee structure.

10 alternatives to Frontier Airlines

  1. 1Southwest Airlines: Travel App icon

    #1Southwest Airlines: Travel App

    Southwest Airlines

    4.8(7.3M)
    Free
    87% similar
    Get on App Store

    Why it's similar

    Southwest shares Frontier's budget-friendly positioning and full app, booking, check-in, boarding passes, and trip management. Both target cost-conscious domestic travelers. At 4.84 across 6,997,194 ratings it is hugely popular and far outrates Frontier.

    How it differs

    Southwest famously includes two free checked bags and no change fees, a sharp contrast to Frontier's pay-for-everything model. It is a fuller, more forgiving experience, so it suits travelers who want budget fares without Frontier's nickel-and-dime fees and glitches.

    United Airlines

    4.8(8.5M)

    Get on App Store

    Why it's similar

    United shares Frontier's full airline-app toolkit, booking, check-in, saved TSA and payment info, mileage tracking, and mobile boarding passes. Both keep your whole trip on your phone. At 4.78 across 7,919,126 ratings it is one of the most-used airline apps.

    How it differs

    United is a full-service carrier with a far broader network and included amenities rather than Frontier's bare-bones budget model. Reviewers want better search filtering, but the app is robust, so it suits travelers who want more reliability and reach than Frontier's no-frills approach offers.

    Spirit Airlines

    4.8(2.1M)
    88% similar
    Get on App Store

    Why it's similar

    Spirit Airlines is the closest match, another ultra-low-cost carrier whose app handles trips, check-in, real-time updates, mobile boarding passes, and adding bags or seats. Both run the same a-la-carte budget model. At 4.82 across 2,071,109 ratings it is heavily used.

    How it differs

    Spirit reviewers report the same pain points as Frontier: surprise carry-on and bag fees at the gate, and a system that splits travel companions into separate seats unless you pay. The low base fare and add-on model mirror Frontier closely, so it suits the same budget travelers willing to manage fees.

    Get on App Store

    Why it's similar

    Breeze Airways shares Frontier's budget-carrier app, booking, check-in, boarding passes, and trip management for low-cost domestic flights. Both serve cost-minded travelers. At 4.79 across 108,348 ratings it is well-rated.

    How it differs

    Breeze focuses on underserved point-to-point U.S. routes with a newer fleet and a friendlier reputation than Frontier's. It still charges for extras, but reviews skew more positive, so it suits travelers who want budget fares with a smoother experience than Frontier often delivers.

    Why it's similar

    Ryanair shares Frontier's ultra-low-cost model and app, booking cheap fares, check-in, mobile boarding passes, and adding bags and seats. Both run a fee-heavy budget operation. It rates 4.49 across 68,680 ratings.

    How it differs

    Ryanair is Europe's budget giant, so its routes serve Europe rather than Frontier's U.S. network. The fee-laden model feels familiar, but the geography differs, so it suits travelers flying within Europe rather than those needing a U.S. Frontier alternative.

    Why it's similar

    Ethiopian Airlines shares Frontier's airline-app core, booking one-way or round-trip flights, fare search with money or miles, seat and meal selection, and payment. Both manage your full trip from the app. It rates 4.74 across 19,641 ratings.

    How it differs

    Ethiopian is a full-service international carrier serving Africa and global long-haul routes rather than Frontier's U.S. budget flights. The service level and network are entirely different, so it suits international travelers rather than those seeking a domestic Frontier alternative.

    Why it's similar

    All Airlines shares Frontier's booking purpose, searching and comparing flights across major airlines including Frontier, American, and Southwest to find low fares. Both help you book a flight from your phone. It rates 4.27.

    How it differs

    All Airlines is a third-party flight-search aggregator, not an airline app like Frontier, so it points you to carriers rather than managing your specific Frontier trip. With 51 ratings it is small, so it suits comparison shopping over Frontier's direct booking and check-in.

    Why it's similar

    Sun Country shares Frontier's low-cost app essentials, check-in, mobile boarding passes saved to Apple Wallet, and trip booking and management. Both serve budget-focused travelers. It rates 2.68.

    How it differs

    Sun Country is a smaller U.S. budget-and-charter carrier with limited routes, and its 2.68 rating, the lowest here, points to a rough app experience. With 213 ratings it is far less proven than Frontier, so it suits travelers on its specific routes willing to overlook the issues.

    Why it's similar

    Sunrise Airways shares Frontier's trip-management essentials, booking, comparing fares, seat selection, check-in, and keeping flights in one place. Both put the core travel flow on your phone. It rates 4 across a tiny base.

    How it differs

    Sunrise Airways is a Caribbean-focused carrier rather than Frontier's U.S. budget network, so its routes serve that region. With only 6 ratings it is unproven, so it suits travelers flying the Caribbean over those seeking a U.S. Frontier substitute.

    How it differs

    Flair is Canada's low-cost carrier, so its routes serve Canada and nearby destinations rather than Frontier's U.S. network. It has no App Store ratings yet, leaving it unproven, so it suits Canadian budget travelers rather than a U.S. Frontier alternative.

Embedding similarity

Every app in our database carries a dense vector embedding derived from its title, subtitle, full description, and category metadata. To find apps similar to Frontier Airlines, we compute cosine distance against every other app and keep the closest 30. The similarity score shown on each pick is 1 - distance/2 clamped to [0,1] — 100% means the embedding spaces are identical, 0% means orthogonal.

Ranking

Apps from Frontier Airlines's own developer are left out. The 10 most similar of the rest are ordered by App Store rating times the logarithm of their rating count, so a 4.8-star app with 100,000 ratings ranks above a 4.5-star app with 200 ratings.
