Frontier Airlines can advertise some of the lowest fares in the United States, but that low starting price comes with trade-offs. Many passenger complaints involve extra fees, flight disruptions, seating, baggage, refunds, or the difference between a bare fare and the experience travelers expected. Current government data shows that some of those concerns have a factual basis, although Frontier has also expanded its fare bundles, customer support, seating choices, and route network.
Quick Answer
Frontier Airlines gets many complaints because its ultra-low-cost model separates the base fare from many extras, while delays, baggage problems, refunds, and denied boarding can make disruptions more frustrating. Current DOT data also shows below-average 2026 on-time performance. The trade-off is that Frontier can still offer very low fares for travelers who understand the rules.
Key Takeaways
- Frontier had 23.3 complaints per 100,000 boarded passengers in 2024, the highest ratio among the 10 largest U.S. airlines in a U.S. PIRG analysis of DOT data.
- Frontier was 72.6% on time from January through May 2026, compared with 76.8% overall among the marketing carriers in the DOT report.
- Every Frontier ticket includes one personal item, but carry-on bags, checked bags, advance seat selection, and other extras depend on the fare or bundle you buy.
- Standard seating has standard legroom, while Premium, UpFront Plus, and the newer First seating products offer more space or other benefits.
- Frontier can still be a good value on the right route, but compare the total checkout price and backup-flight options rather than judging the trip by the advertised base fare alone.
Why Frontier Airlines Gets So Many Complaints
Frontier operates as an ultra-low-cost carrier. The basic idea is simple: keep the starting fare low and let passengers pay separately for many optional services. That model can work well for a traveler carrying only a small personal item, but it can feel expensive or restrictive once bags, a preferred seat, priority services, or other extras are added.
The complaint numbers help explain Frontier’s reputation. A U.S. PIRG Education Fund analysis of Department of Transportation data found that Frontier received 23.3 complaints per 100,000 boarded passengers in 2024. That was the highest ratio among the 10 largest U.S. airlines for the third consecutive year. Spirit was second at 12.8, while the 10-airline average was 7.2.
Note: A DOT complaint is a passenger complaint case, not a finding that the airline broke a rule. Complaint statistics are still useful for spotting recurring areas of dissatisfaction, especially when compared across carriers using the same reporting framework.
Customer Service: What Frontier Offers Now
Poor customer service is one of the complaints frequently associated with Frontier, particularly when a delayed flight, baggage problem, refund, or rebooking issue requires help. However, it is no longer accurate to describe Frontier as offering only automated assistance.
Frontier’s current customer-support information says agents are available 24 hours a day, seven days a week through telephone support, live chat, and WhatsApp. Many routine changes can also be handled through the website or mobile app.
The existence of live support does not mean every traveler is satisfied with the result. In the DOT’s May 2026 complaint data, Frontier had 465 complaint cases. The largest categories included 107 refund cases, 75 flight-problem cases, 72 baggage cases, 60 reservation/ticketing/boarding cases, and 33 customer-service cases.
That distinction matters: the fair criticism is not that Frontier has no customer-service channels, but that passengers continue to report problems involving service, refunds, disruptions, and other parts of the travel process.
Unreliable Flight Schedules
Delays can be especially disruptive on an airline where a particular route may not have another convenient departure later the same day. Weather, air-traffic-control restrictions, maintenance, crew problems, airport congestion, and other factors can affect any carrier, so it is more useful to look at comparative performance than to assume every delay is the airline’s fault.
The latest U.S. Department of Transportation Air Travel Consumer Report shows that Frontier was 72.6% on time from January through May 2026. The overall figure among the reporting marketing carriers was 76.8%. Frontier ranked seventh of nine marketing carriers on that year-to-date measure.
May itself was better: Frontier recorded a 76.1% on-time arrival rate, compared with 77.8% overall. DOT counts a flight as on time when it arrives less than 15 minutes after the scheduled arrival time.
Frontier’s 2026 on-time rate through May was 72.6%, versus 76.8% overall among the marketing carriers in the DOT report.
If your trip includes a cruise departure, wedding, international connection, prepaid tour, or another event you cannot afford to miss, consider arriving a day early regardless of airline. Also check how many later Frontier flights operate on your exact route. A low fare is less attractive when the next available nonstop is not until the following day.
Hidden Fees and Extra Charges
“Hidden fees” is not the most precise description of Frontier’s pricing. Frontier publishes its baggage and optional-service rules, but its à-la-carte structure can still surprise someone who compares only the initial airfare shown in search results.
According to Frontier’s current baggage rules, every ticket includes one personal item measuring no more than 18 by 14 by 8 inches, including handles, wheels, and straps. Frontier currently allows that personal item to weigh up to 35 pounds.
A carry-on bag can measure up to 24 by 16 by 10 inches and weigh up to 35 pounds. Standard checked bags can measure up to 62 linear inches and generally weigh up to 40 pounds unless a qualifying bundle or status benefit provides a higher allowance.
Carry-on and checked-bag prices are not one fixed amount. Frontier says prices vary according to the trip and when the bag is purchased, so the correct amount is the price shown for your itinerary.
What Is Included Depends on the Fare or Bundle
The most basic ticket includes the personal item, while Frontier’s current bundles can package common extras:
- Economy bundle: personal item, carry-on bag, Standard seat selection, and no change/cancel fee.
- Premium bundle: personal item, carry-on bag, Premium seat selection, Board First, and no change/cancel fee.
- Business bundle: personal item, carry-on bag, two checked bags up to 50 pounds each, Board First, no change/cancel fee, and qualifying front-cabin seating.
Availability, pricing, fare differences, and exact bundle terms can change, so use the details displayed for the specific flight you are buying.
Warning: Compare the final checkout total, not just the first airfare you see. Add the bags and seats you actually need before deciding whether Frontier is cheaper than another airline. Measure and weigh your bags at home because an item outside Frontier’s limits can trigger an additional charge at the airport.
Federal fee-disclosure rules have also changed. In July 2026, the DOT issued a final rule restoring the ancillary-fee disclosure standards that existed before the department’s vacated 2024 rule. Travelers should therefore rely on the current airline checkout page and current DOT rules rather than older articles describing the 2024 regulation as if it were still in force.
Uncomfortable Seating and Limited Legroom
| Frontier Seat Type | What It Offers | Main Trade-Off |
|---|---|---|
| Standard | Standard legroom and space in the middle or rear portions of the cabin. | No extra-legroom benefit. |
| Preferred | A seat positioned closer to the front of the aircraft. | Location benefit rather than an extra-legroom product. |
| Premium | Extra legroom. | Normally costs more or comes with an eligible bundle/status benefit. |
| UpFront Plus | Front-of-plane seating with extra legroom and a guaranteed empty middle seat. | Limited availability and a higher price than Standard seating. |
| First seating | Newer 2×2 seating being introduced at the front of aircraft. | Still being introduced across the fleet, so availability depends on the aircraft and flight. |
Seat comfort is subjective, so a made-up numerical “comfort rating” is not useful. The factual distinction is that Frontier’s Standard seats provide standard legroom, while higher seat categories provide benefits such as extra legroom, a location closer to the front, or an empty middle seat.
Travelers who are tall, need additional space, or simply dislike a tighter economy experience should price an upgraded seat before booking. That gives you a fairer comparison against another airline whose standard fare may already include a seat you prefer.
If you do not choose a seat, Frontier says it can assign one from the remaining inventory. Families have separate fee-free family-seating protections subject to Frontier’s stated conditions.
Lack of Amenities and In-Flight Entertainment
Frontier’s stripped-down onboard product is another important difference from many full-service airlines. As of July 2026, Frontier states that its flights do not currently offer Wi-Fi, television, movies, other in-flight entertainment, or electrical outlets.
Food and drinks are available for purchase, but Frontier says they are not complimentary. For a short flight, that may not matter. On a longer journey, it is worth downloading entertainment, charging your devices, and bringing an approved snack before boarding.
Frontier says Starlink Wi-Fi installation is scheduled to begin in early 2027, so the current no-Wi-Fi experience is expected to change.
That planned upgrade is important for freshness: articles saying Frontier simply “does not have Wi-Fi” without mentioning the announced rollout will become outdated as equipped aircraft enter service.
Route Network and Rebooking Trade-Offs
It is no longer accurate to characterize Frontier as an airline with only a small selection of destinations. Frontier currently says it serves more than 100 destinations across the United States, Mexico, the Caribbean, and Central America.
The more useful concern is frequency. A large route map does not mean every city pair has several daily departures. On a route that operates only on selected days or has limited frequency, a cancellation can leave fewer convenient same-airline recovery options.
Before booking an important trip, search the same route for the following day as well as the day you plan to travel. If Frontier has several departures, the disruption risk is easier to manage. If the next practical flight is much later, factor that into the value of the cheaper fare.
Overbooking and Cancellations
Airlines are legally allowed to oversell flights, although the U.S. Department of Transportation requires specific procedures and protections. When an oversold flight does not have enough seats, an airline must first seek volunteers before involuntarily denying boarding to passengers.
For Frontier, this is not merely a hypothetical issue. The July 2026 DOT report shows that Frontier recorded 1,459 involuntary denied boardings during the first quarter of 2026 among 8,108,044 enplaned passengers. That equals 1.80 involuntary denied boardings per 10,000 passengers, the highest rate among the 13 reporting operating airlines in that DOT table.
If you are involuntarily bumped because a flight is oversold, eligibility for compensation depends on factors such as whether you had a confirmed reservation, checked in and reached the gate on time, where the flight departs, and how late the substitute transportation gets you to your destination. DOT requires an involuntarily bumped passenger to receive a written explanation of applicable rights.
Your Refund Rights After a Cancellation or Major Schedule Change
A cancellation is different from ordinary dissatisfaction with the trip. Under current DOT refund rules, you are entitled to a refund when an airline cancels your flight and you choose not to accept rebooking, travel credits, vouchers, or other alternative compensation.
A significant schedule change can also create a refund right. DOT currently defines qualifying timing changes to include a departure or arrival shifted by at least three hours on a domestic itinerary or six hours on an international itinerary. Other qualifying changes can include a changed origin or destination airport, additional connections, or certain downgrades.
Pro Tip: If Frontier cancels or significantly changes your flight and you do not want the alternative itinerary, do not assume you must accept a voucher. Tell the airline you are declining the alternative. Qualifying refunds are returned to the original form of payment, generally within seven business days for credit-card purchases or within 20 days for other payment methods.
DOT also says optional-service fees can be refundable when the paid service is unavailable through no fault of the passenger. Keep receipts and screenshots showing what you purchased if a disruption affects bags, seats, or other paid services.
Overall Quality and Satisfaction: Why Experiences Vary
Frontier’s reputation makes more sense when you separate two questions: Is the airline inexpensive? and Does the product match what the traveler expected? A passenger who books a low fare, travels with one correctly sized personal item, accepts a Standard seat, and reaches the destination on time may consider the trip an excellent value. A traveler who adds several bags and seats or suffers a disruption can have a very different experience.
The current data does support several reasons for caution. Frontier’s 2024 complaint rate was unusually high, its 2026 year-to-date on-time performance through May trailed the overall DOT figure, and its Q1 2026 involuntary denied-boarding rate was the highest in the relevant DOT operating-carrier table.
At the same time, calling Frontier simply “bad” misses the airline’s value proposition. Its fares can make a trip possible for travelers who otherwise would not fly, and its network now reaches more than 100 destinations. The key is understanding exactly what the ticket includes and how much risk you can tolerate if the schedule changes.
What Frontier Is Changing in 2026 and 2027
Some older Frontier reviews do not reflect the product now being rolled out. Frontier is introducing new 2×2 First seating at the front of its aircraft during 2026, alongside existing Premium and UpFront Plus options. Availability depends on the aircraft and flight while the fleet transition continues.
The airline also announced that Starlink installation will begin in early 2027. Until an individual aircraft is equipped, travelers should still plan for no onboard Wi-Fi or electrical outlets.
Frontier has also expanded its Economy, Premium, and Business bundles, which can package baggage, seat selection, boarding benefits, and greater change/cancellation flexibility. These changes do not erase past complaints, but they mean older descriptions of Frontier’s product can quickly become inaccurate.
How to Avoid the Most Common Frontier Problems
A little preparation can prevent many of the surprises that generate negative reviews:
- Compare the total trip price. Add the bags and seats you actually intend to buy before comparing Frontier with another airline.
- Measure your personal item. Frontier’s current maximum is 18 by 14 by 8 inches, including handles, wheels, and straps.
- Check your bag weight. The current standard carry-on limit is 35 pounds, while a standard checked bag generally has a 40-pound limit unless your bundle or status says otherwise.
- Look at flight frequency. Check when the next Frontier flight operates in case your original departure is canceled.
- Download entertainment. Frontier currently has no onboard Wi-Fi, TV, movies, or electrical outlets.
- Save your booking records. Keep receipts and screenshots showing purchased bags, seats, bundles, and schedule changes.
- Know your refund rights. A canceled or significantly changed flight can entitle you to a refund when you decline the alternatives offered.
Choosing an airline is much like choosing the right equipment for any trip: the cheapest option is only a bargain when it meets your actual needs. For air travel, that means looking beyond the advertised fare and checking the complete price, schedule, baggage rules, seat, and backup options before paying.
