American and Frontier share one distinction no airline wants: both tied for last in the Wall Street Journal’s 2025 airline rankings. American got there with a 1.93 percent cancellation rate, the worst among major US carriers. Frontier got there by finishing dead last in 4 of 7 categories. They failed for different reasons, but they both failed.
Despite that shared ranking, these are fundamentally different products. American is a full-service oneworld carrier with 350-plus destinations, domestic First Class, Flagship Business on international routes, free Wi-Fi, and the AAdvantage loyalty program. Frontier is an ultra-low-cost carrier with approximately 115 destinations, no premium cabin (until a limited First Class launches in 2026), paid Wi-Fi, and the GoWild All-You-Can-Fly Pass.
The question is whether American’s complete product justifies its higher fares when both airlines deliver bottom-tier reliability. For most travelers, yes. American includes a carry-on on every fare, charges a flat $45 for checked bags (comparable to or less than Frontier’s dynamic pricing), and offers global network connectivity through oneworld. Frontier’s only advantage is for personal-item-only travelers who want the absolute lowest base fare and are willing to accept everything that comes with it.
What We Looked For
- Reliability, where both airlines rank at the bottom of the industry
- Total trip cost after fees, because Frontier’s base fare hides the real price
- Carry-on policies, where American’s free inclusion is a decisive difference
- Seat comfort, 30 inches versus 28 inches in standard economy
- Route network, global oneworld carrier versus domestic-focused ULCC
- Loyalty programs, AAdvantage with oneworld partners versus GoWild Pass
Which airline charges less for bags, American or Frontier?
American includes a free carry-on on every fare and charges less per checked bag. Frontier charges 59 dollars for a carry-on and uses dynamic pricing for checked bags (typically 47 to 63 dollars at booking).
American includes a carry-on on every fare, including Basic Economy. Frontier does not include a carry-on on any fare.
Carry-on. American: free on all fares, 22x14x9 inches. Frontier: 59 dollars at booking, 24x16x10 inches, 35-pound weight limit enforced at the gate. Frontier’s box is larger but the 59-dollar fee is the story.
Personal item. American allows 18x14x8 inches. Frontier specifies 14x18x8 inches and enforces with a gate sizer. Effectively the same dimensions.
Checked bags. American charges 45 dollars for the first checked bag (increasing to 50 dollars for Basic Economy starting May 2026) and 55 dollars for the second. Frontier uses fully dynamic pricing, with checked bags typically costing 47 to 63 dollars at booking and more at check-in or the airport.
Total cost example. Dallas to Denver, round trip. Frontier base fare: 69 dollars each way (138 dollars total). Add carry-on: 59 dollars each way (118 dollars). Total: 256 dollars. American fare on the same route: approximately 139 dollars each way (278 dollars total), carry-on included. American is 22 dollars more, but you get an included carry-on, 2 extra inches of legroom, free Wi-Fi, and AAdvantage earning on Main Cabin fares. The 22-dollar difference is not a savings on Frontier. It is a downgrade.

- Winner for carry-on inclusion: American (free on all fares vs $59 on Frontier)
- Winner for checked bag fees: American ($45 flat vs Frontier’s dynamic $47-63+)
- Winner for personal-item-only travel: Frontier (lower base fares)
- Winner for carry-on size: Frontier (24x16x10 vs 22x14x9)
Is American or Frontier more reliable for on-time arrivals?
Neither ranks well. Frontier posted approximately 74 percent on-time in 2025. American posted 72.66 percent. Both tied for last in the WSJ’s 2025 rankings.
This is a comparison where nobody wins.
American’s full-year 2025 on-time rate was 72.66 percent. The cancellation rate was 1.93 percent according to DOT data, the worst among major carriers. The WSJ reported it as high as 2.2 percent. American tied for last in the Wall Street Journal’s 2025 airline rankings.
Frontier’s full-year 2025 on-time rate was approximately 74 percent. Frontier finished dead last in 4 of 7 WSJ categories and tied with American for last overall. Historical context: Frontier posted approximately 63 percent on-time in 2024, so the 74 percent is an improvement.
On cancellation recovery, American has the clear edge. American operates over 6,700 daily flights across eight hubs. If an American flight cancels at DFW, another American departure is likely within hours. If a Frontier flight cancels at DEN, the next one may not be until tomorrow. Frontier’s lower frequency on many routes makes cancellations harder to recover from.
- Winner for on-time arrivals: Frontier (~74% vs 72.66%, marginal)
- Winner for cancellation rate: Frontier (lower than American’s industry-worst 1.93%)
- Winner for recovery after disruption: American (6,700+ daily flights vs fewer options)
Does American or Frontier have more legroom?
American offers approximately 30 inches of seat pitch versus Frontier’s 28 to 29 inches. Frontier’s Stretch seats reach 38 inches but cost extra.
Standard economy. American offers approximately 30 inches of seat pitch on narrowbody aircraft. Frontier offers 28 to 29 inches, among the tightest in US aviation. Two inches is the difference between uncomfortable and cramped on flights over two hours.
Extra legroom. American Main Cabin Extra offers approximately 34 inches of pitch with priority boarding. Frontier Stretch seats offer 33 to 38 inches. Frontier’s top-end Stretch rows are roomier than Main Cabin Extra at the high end, but they are an expensive add-on to a fee-heavy base fare.
First Class. American offers domestic First Class on all mainline narrowbody aircraft with recliner seats, complimentary meals, and priority services. Flagship Business on widebody routes offers lie-flat suites, with the new Flagship Suite on A321XLR aircraft launching in late 2025. Frontier is launching a limited First Class product in early 2026, but details remain sparse and scope will be limited compared to American’s established offering.
Wi-Fi. American provides free high-speed Wi-Fi for AAdvantage members on approximately 90 percent of its fleet, sponsored by AT&T. Frontier charges for Wi-Fi.
Entertainment. American streams free content to personal devices via the American Airlines app, including Apple TV+ content. No seatback screens on narrowbody aircraft. Frontier has no seatback screens and offers limited streaming through the Frontier app.
- Winner for standard legroom: American (30” vs 28-29”)
- Winner for Wi-Fi: American (free for AAdvantage members)
- Winner for maximum extra legroom: Frontier Stretch (up to 38” vs 34”)
- Winner for premium cabin: American (established First Class and Flagship Business)
Does American or Frontier fly to more destinations?
American serves over 350 destinations across 60-plus countries. Frontier covers approximately 115 domestic-focused destinations.
American flies to over 350 destinations in more than 60 countries. Eight major hubs at DFW, CLT, MIA, ORD, PHL, LAX, PHX, and DCA. Oneworld alliance access to 14-plus partner airlines including British Airways, Japan Airlines, and Qantas. International service on widebody aircraft. Adding 15-plus new routes for 2026.
Frontier serves approximately 115 destinations, focused on major domestic markets with Denver as its primary hub. International service is limited to Mexico and the Caribbean. No alliance partnerships. No widebody aircraft. No transoceanic flights.
If you fly internationally at all, American is the only option. Domestically, Frontier competes on many of the same routes (Denver, Orlando, Las Vegas, Phoenix) but with less frequency and no global connectivity.
- Winner for international reach: American (350+ destinations, 60+ countries, oneworld)
- Winner for domestic budget routes: Frontier (lower base fares on select routes)
Is AAdvantage or FRONTIER Miles the better loyalty program?
AAdvantage is the stronger program, with oneworld partners, elite upgrades, and Admirals Club access. Frontier’s GoWild Pass is unique but suits only ultra-flexible travelers.
AAdvantage earns miles based on ticket price. Miles average approximately 1.3 cents each. Elite tiers unlock complimentary upgrades, preferred seating, and lounge access. Oneworld membership means miles earn and burn across 14-plus airlines. Note: as of December 2025, Basic Economy no longer earns AAdvantage miles or Loyalty Points.
FRONTIER Miles earns miles on flights and purchases. The GoWild All-You-Can-Fly Pass (349 to 599 dollars per year) is the program’s unique feature, offering unlimited flights booked one day before departure for one cent plus taxes. For travelers who fly 6 to 8 or more times per year with total flexibility and only a personal item, GoWild offers value no legacy program can match.
For travelers who fly frequently enough to earn status, AAdvantage provides dramatically more value through upgrades, lounge access, and partner airline redemptions. GoWild is a different kind of value proposition, one that works brilliantly for a narrow audience and poorly for everyone else.
- Winner for loyalty value: AAdvantage (oneworld partners, upgrades, Admirals Club)
- Winner for lounge access: AAdvantage
- Winner for ultra-flexible travelers: FRONTIER Miles (GoWild Pass)
Who Should Pick American
- You want a carry-on included on every fare, including the cheapest
- You fly internationally or need oneworld alliance partner access
- You value free Wi-Fi and in-flight streaming content
- You want the option to upgrade to First Class or Flagship Business
- You prefer 30 inches of legroom over 28 inches
- You want a larger network for recovery when flights are delayed or cancelled
- You want to earn miles toward upgrades and partner redemptions
Who Should Pick Frontier
- You always fly personal-item-only and never need an overhead bag
- You want the absolute lowest base fare available on your route
- You have the flexibility to use the GoWild Pass (booking one day before departure)
- You are willing to accept a lower reliability ranking for a lower price
- You can tolerate 28 inches of seat pitch
- You value Frontier’s larger carry-on dimensions (24x16x10) when you do pay for a bag
The Bottom Line
American and Frontier both ranked last in the Wall Street Journal’s 2025 airline analysis, but they are not the same kind of bad. American is a complete airline with a reliability problem: it offers everything a traveler needs (bags, legroom, lounges, global reach) but delivers it with the worst cancellation rate in the industry. Frontier is an incomplete airline with a lower price: it offers a seat, a personal item, and charges for everything else, while also delivering poor reliability.
For personal-item-only travelers who want the lowest possible base fare, Frontier delivers. For everyone else, American’s carry-on inclusion, 30-dollar checked bag advantage, free Wi-Fi, and oneworld network make it the more complete option, even with its reliability issues. When both airlines are going to frustrate you on delays and cancellations, you might as well be frustrated in a seat with a carry-on, free Wi-Fi, and the ability to rebook on oneworld partners.
