Frontier Group Holdings flies mainly leisure travelers and people visiting friends and relatives within the United States and to selected destinations elsewhere in the Americas. Passengers buy a base ticket and pay separately for extras such as baggage and advance seat selection, or choose a bundle. These non-fare charges provide most of its revenue. Its website and mobile app are its main ticket-sales channels.
The business depends on attracting price-sensitive travelers, keeping aircraft flying frequently and persuading passengers to pay for extras. Frontier uses only leased Airbus A320-family aircraft; a common aircraft family simplifies crew assignments and maintenance, but also leaves it dependent on Airbus. It must maintain U.S. Department of Transportation and Federal Aviation Administration authorizations to operate, while international routes also require government approvals and depend on air transport agreements.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
Beyond this list, watch Frontier’s low-fare rivalry with Spirit Airlines and its reliance on Airbus aircraft deliveries and Pratt & Whitney engines for fleet growth.
Allegiant competes with Frontier for price-sensitive U.S. leisure travelers, with both selling low base fares and charging separately for extras such as bags and seat selection. Watch Allegiant’s ticket and extras revenue from leisure travelers in underserved small and medium-sized U.S. cities.
Southwest competes with Frontier for passengers buying competitively priced flights within the U.S. and to nearby international destinations. Watch Southwest’s fares and frequent nonstop service, which give those travelers alternatives to Frontier’s low-fare flights.
JetBlue competes with Frontier for travelers buying competitively priced flights to Florida, the Caribbean and other U.S. and nearby international destinations. Watch JetBlue’s fares alongside its included carry-on bag and Wi-Fi, a different offer from Frontier’s low base fare and separately charged extras.
United competes with Frontier for U.S. passengers through its domestic flight network, including a Denver hub in Frontier’s home market. Watch United’s Denver service for a local view of the flight choices competing with Frontier.
American Airlines Group’s domestic capacity and fares matter to Frontier because its broad passenger network competes with Frontier’s low-fare flights. Watch American’s domestic flight additions and pricing: Frontier says excess competing capacity can bring route-by-route fare discounting.
Delta’s domestic flight capacity and fares bear on Frontier’s pricing because both sell flights to U.S. passengers. Watch Delta’s flight growth at its core hubs, where it focused on adding service in 2025.
Volaris and Frontier both rely on leisure and visiting-friends-and-relatives travelers buying low base fares and paid extras; they also market partner-operated flights through a codeshare partnership. Watch Volaris’s revenue from optional services, which it uses to help keep base fares low and attract more passengers.
Alaska Air Group’s Alaska and Hawaiian airlines compete with Frontier for domestic passengers buying flights. Passenger transportation generated 90% of the group’s consolidated revenue in 2025, making that revenue line the clearest place to follow its passenger business rather than cargo or loyalty revenue.
United Airlines Holdings, Inc. earningsUAL
United Airlines' report will show how its flights and fares in Denver are changing, in one of Frontier's most important home markets.
Watch United's Denver capacity and fares. More seats or lower fares would give passengers more choices and could put added pressure on Frontier to win traffic and fares in its home market; steady capacity and firm fares would suggest less pressure from this rival. The point is United's competition in Frontier's home market, not United's overall performance.
EIA Crude Oil Stocks Change (Oct/16)
EIA stock reports track how much crude oil and fuel is stored in the United States, which can shift the fuel prices Frontier pays and its cost of flying passengers.
Read the stock change as a signal about fuel-cost pressure: rising stocks can ease supply and costs for Frontier, while falling stocks can tighten supply and raise costs, potentially faster than fares adjust.

Frontier's report will show whether fares and revenue from extras such as bags and seat selection are keeping pace with the cost of flying each seat one mile.
Read revenue per passenger alongside cost per available seat mile—the cost of flying one seat one mile. Separate fare revenue from extras such as bags and seat selection. If revenue per passenger improves and extras hold up while unit costs are flat or lower, Frontier is earning more from passengers without giving the gain back in flying costs. If costs rise faster or extras weaken, fare growth is not enough to support the economics of each flight.
Allegiant Travel Company earningsALGT
Allegiant's report will show whether leisure travelers are still buying low-fare tickets and paid extras, a model it shares with Frontier.
Read Allegiant's ticket revenue alongside its revenue from extras. If both hold up, leisure travelers are still flying and paying for services such as bags and seat selection, supporting the model Frontier also uses. If extras weaken or ticket revenue falls, travelers may be spending less or flying less, putting Frontier's non-fare revenue and passenger demand in focus.
