Is Frontier a Good Airline? The Honest Answer for Cheap-Flight Hunters

Frontier is a good airline if you want the lowest possible base fare and you can travel with just a personal item. It’s a less comfortable, less ideal choice if you need a carry-on, want to pick your seat, or care about a reliable schedule that recovers quickly when things go sideways. 

Once you start adding those extras back in, a Frontier ticket often isn’t much cheaper than a regular fare on a full-service airline. So the question isn’t really if it’s “good” or “bad,” but “what are you looking for?”

We’ll walk through what Frontier actually costs after the fees, what the flight itself feels like, how safe and reliable it is, and how it stacks up against other carriers now that the budget landscape has shifted. 

When Frontier is worth it (and when it isn’t)

Frontier runs on an ultra-low-cost model. The airline strips the fare down to the flight and the seat, then sells everything else back to you one item at a time, including the luxury of choosing which seat you actually sit in. The math works out beautifully for some travelers and painfully for others.

Frontier is worth it if:

• You can pack everything into a free personal item that fits under the seat.
• Your schedule is flexible, so a delay or a change won’t break your plans.
• You don’t care about picking your seat, and you’ll bring your own snacks.
• Frontier flies your route nonstop (you avoid risking a tight connection).

Skip it if:

• You need a carry-on bag or a checked bag. The add-on fees can quickly erase the savings.
• You want to sit with your travel companions and choose your seat in advance with no additional fees.
• You’re traveling for a time-sensitive event, like a cruise departure, a wedding, or a same-day connection.
• You value legroom, recline, and free drinks on board.
• You want easy rebooking if your flight is delayed or canceled (a low-cost carrier with fewer daily flights has fewer seats to move you to).

What Frontier actually costs (base fare vs. extra fees)

The headline fare you see on a search engine is usually only a fraction of the story. Frontier’s base ticket covers your seat on the plane (though not a specific one—that costs extra) and one free personal item up to 18 x 14 x 8 inches, which must fit under the seat in front of you. Everything beyond that is an a la carte charge.

The price of each add-on climbs the longer you wait to buy it. A carry-on you add during booking is cheaper than the same bag paid for at the gate.

That’s the “fee trap” in a nutshell: The most flexible travelers will be able to get by, but if you want any sort of customization, it’s going to cost you. Add a carry-on, a checked bag, and a seat assignment, and a $49 fare can become a $150 fare real quick.

Here’s a snapshot of Frontier’s fees. Ranges reflect the difference between buying online during booking (cheapest) and paying later or at the airport (most expensive), and prices also vary by route and demand.

Note: Fees are current as of September 2026 and are subject to change at Frontier’s discretion. Always confirm the exact cost for your route on Frontier’s site before you book.

Our honest take: If you truly can travel with only a personal item, Frontier can be a fine deal. The trouble starts the moment you need to bring more—that’s where the low fare stops being low.

Is Frontier Airlines safe?

Yes, Frontier is safe. Like all mainstream US airlines, it operates under the Federal Aviation Administration rules, and it has a solid operational safety record.

 “Budget airline” sometimes gets confused with “cutting corners on safety.” It doesn’t work that way. The FAA sets uniform standards for aircraft maintenance, pilot training and certification, crew rest requirements, and inspections, and those standards apply the same to Frontier as they do to Delta, United, and American.

Frontier also flies one of the youngest fleets in the US, built around fuel-efficient Airbus A320neo-family jets, which is part of how it keeps costs down. A cheaper ticket buys you fewer comforts, not a less-safe airplane.

What it’s like to fly Frontier

Boarding a Frontier plane, you’ll feel the stripped-down experience right away, so keep your expectations in check.

The seats are slimline models designed to be light and to pack more rows into the cabin. Most of them don’t recline (or barely do), and the padding is thin. Legroom is tight, and the tray table is a small ledge rather than a full-size tray, big enough for a phone or a drink but not much else. If you’re tall, a long flight can feel long.

There’s no free food or drink service. Water, soda, coffee, and snacks are all for sale, so bring your own empty bottle to fill after security, and pack a snack if you want one. There’s also no seatback screen and no free Wifi, so download your entertainment before you board.

Boarding follows Frontier’s zone system, and this is where the personal-item-only rule is enforced. Gate agents actively check bag sizes, and if your “personal item” is really a carry-on, you’ll be charged the higher gate price on the spot.

Many travelers assume they can slip a larger bag through, and they end up frustrated. Pack to the personal-item dimensions, or pay for the carry-on ahead of time online where it’s cheapest.

In the end, none of this makes the flight unpleasant if you know what you signed up for. The complaints usually come from people who expected a full-service experience at a bare-bones price.

Frontier vs. other carriers

Stack Frontier up against a legacy carrier like Delta, United, or American, and the trade-off is very clear. Those airlines cost more up front but bundle a lot: a personal item and a carry-on (not including United basic economy), seat selection on most fares, free drinks, larger networks with more daily flights, and loyalty programs with farther reach. When your flight goes wrong, they also have far more seats and routes to rebook you onto. Frontier wins on base price and loses on comfort, flexibility, and recovery.

Against other budget carriers, the comparison is more interesting, and it changed a lot after Spirit Airlines (Frontier’s longstanding ultra-low-cost rival) ceased operations in May 2026. With Spirit gone, Frontier is effectively the largest remaining ultra-low-cost carrier in the US. On nonstop routes, Frontier’s fares are hard to beat.

Frontier’s on-time performance and reliability

According to the US Bureau of Transportation Statistics, which publishes the official government numbers, Frontier finished last for on-time performance among the major US airlines in 2025, ranking #10 out of 10. 

Why is reliability so low, you ask? A budget carrier runs a leaner operation with fewer daily flights, so when weather or a mechanical issue hits, there simply aren’t as many later flights to move you onto. A delay on a legacy airline might cost you a couple of hours; the same delay on a low-cost carrier can cost you the day. 

Frontier reviews and customer satisfaction

Scroll through enough Frontier reviews on Reddit, Google, Trustpilot, and ConsumerAffairs, and the story becomes clear.

The general praise is almost always about price. Frontier is cheap, and when everything runs on time, happy fliers say it did exactly what it promised: got them from A to B for pretty darn cheap. 

The main general complaint is the fees, especially the sting of gate-priced bags when someone didn’t realize their carry-on wasn’t free. Travelers also complain about the delays and cancellations, which line up with the on-time data above.

The surprising third is its customer service. Travelers noted that reaching a helpful human during a disruption is nearly impossible. Frontier has also historically drawn a high volume of formal passenger complaints relative to its size.

The overall sentiment is less “this airline is terrible,” and more “this airline is exactly as advertised,” and people who didn’t read the fine print got surprised. Go in knowing the pitfalls, and you’re far more likely to land in the happy camp.

How to find cheap Frontier flights (and know when to book)

If Frontier fits your trip goals, a little strategy goes a long way. Being flexible on dates and times helps too, as Frontier’s cheapest seats cluster on off-peak days and less popular departure times.

For timing, set alerts, and let the data guide you rather than guessing. Going doesn’t typically send Frontier deals. We focus on full-service carriers like Delta, United, and American, and when we do surface a low-cost option, it’s usually on a carrier like Breeze or Avelo.

We love finding low-cost fares on full-service airlines (often with the seat selection and carry-on already baked in). So think of Frontier as a tool for a specific job, and think of Going as the way to take your travel up a step for close to the same money.
