Pros: "The softest landing on our whole trip!"
Read more about Frontier
Pros: "The softest landing on our whole trip!"
Pros: "Seats are not that small . It’s comfortable"
Cons: "Was the worst flight ever check in was opened late , computers were down , boarding was horrific , problems with many people and seating , flight left late ,"
Pros: "Everything good"
Cons: "The chairs"
Cons: "Flight was delayed by almost two hours so I missed the flight from Denver to Charlotte. Because of the way this flight was sold to us and booked through Kiwi.com, there was nothing that could be done to get me on another flight. The only option was to wait for a Frontier flight which wasn't available until Monday morning. I had to book another flight on a different airline at a cost of $600."
Cons: "Negative leg room, Hugh bag fees that were not stated in the original purchase"
Pros: "Boarding was smooth and fast. The travel time was a bit faster than predicted too."
Cons: "With lack of reclining seats and no complimentary snacks or drinks at all, the comfort scale is lacking. Even the tray tables were replaced by miniature, undersized, pieces. Even with the discounted prices, it’s hard to want to fly with them again."
Pros: "The crew was friendly. They got me to and from my destination safely."
Cons: "I resented the fact that we being charged about $3.00 for a can of soda after we paid premium for the flight and there was absolutely no entertainment. Hated the fact that I paid almost $80 just to take my clothes o. My vacation. Guess I should have gone naked, would have been $80 cheaper."
Pros: "Nice crew."
Cons: "Our flight was supposed to leave at 6:40 PM but was bumped back until after 8 PM due to storms in the landing city however two other airlines in the same airport heading to the same city left on time."
Cons: "The flight was delayed and we got a notification from google, but when we called Frontier, they said it was on time. And when we reached the airport they said, its been delayed. It caused a lot of inconvenience. Very unprofessional."
Cons: "The flight was delayed for no reason given. The seats don't go back anymore-that sucks for long flights. To charge $2.99 for a soda that once was complimentary is insane! The bag prices are ridiculous. You trick people by offering ok prices for the original airline ticket, then charge outrageous prices for bags and drinks. Very disheartening. I will never fly Frontier again."
Pros: "Super professional, courteous, and helpful flight staff. Seat was uncomfortable, but it was a short flight, so I had a weird plastic bottle of wine and cared less."
Pros: "We had no issues boarding."
Cons: "The staff were angry, I paid for a direct flight and had a layover added after booking, staff were not happy, they charge for picking a seat, having a soda, seats don't recline, the plane was dirty, flight was late taking off. Instead of getting into Philadelphia via a direct flight early in the afternoon, we had a layover, delayed flight and I got into Philadelphia at rush hour."
Pros: "check in crew were very pleasant and helpful, making the check in process very smooth despite multiple people, skis,etc. You are getting nickeled-and died- but I planned for that in advance, and despite that it was still a value compared to other airlines."
Cons: "seats are uncomfortable. If flights get cancelled (mine were not!), you are screwed because Frontier does not partner with other "sister" airlines, so you will have to wait a long time for a rescheduled flight or change airlines on your own dime"
Pros: "Friendliness of crew. Captains' explanation (on the return leg of our flight) of why it took sooo long to know why our flight was repeatedly delayed. Extra leg room seats for purchase."
Cons: "Having to purchase my seat, paying to have a carry on and for EVERYTHING else- a la carte style!"
Cons: "On a holiday arrived early to avoid traffic and the bag counter wants open. Had to stand there and wait for service, just to print out tickets. I have always scanned directly from my phone. Huge incovience. Flight attendants served to much alcohol to parents with a three month old. Allowed to much traffic through the cabin."
Pros: "Frontier's flights is very inexpensively priced. It is a budget airline but clean and comfortable. Baggage and food are added to your ticket price so if you don't need these items the price is right."
Pros: "Flight was good and landing smooth."
Cons: "No beverages or snacks were offered. The flight was a late night flight and there was no where refreshments or beverages could be purchased, hence I was forced to fast for 6 hours."
Pros: "I thought the planes were nice and clean although I guess that's the point."
Cons: "Charging for the first piece of luggage/carry on just isn't nice. I can see charging for people who fly with excessive pieces but this is my first time flying Frontier and to charge someone who brings one airline approved suitcase just isn't nice. I'm sure it's too much to ask for ANY sort of TV/Movie. I mean you fly to Orlando, if you put on a Disney movie it would be like shooting fish in a barrel and may even keep the kids a little quieter. Seeing as I have no children it would be great to have them slightly entertained if only for a little peace. I could care less about food/beverage options which of course were extra which I quickly realized was the name of your game. My reasonably priced $200 plane ticket became a $340 plane ticket once I realized there are no options but to either pay for my luggage or vacation naked. Also I was charged one price on my departing flight and a different price on my return flight for my luggage. When I asked why I was told the prices changed that very week. How convenient for your airline and nobody else."
Pros: "The crew: Friendly and Professional"
Cons: "Too much nickel and diming: Pay for seat selection, ridiculous fees for baggage, no free drinks..Really?"
Pros: "Literally. Nothing. Showing up at my destination alive, I guess."
Cons: "2 hour delay, then a three hour delay bc of weather. Another 45 minutes taxi-ing, then back at the gate because a passenger had to be escorted off because he didn't have a boarding pass. We were rushed to board he flight in the first place before the flight crew timed out; we finally took off at 2am with exhausted pilots which was terrifying. Also frontier charges for all bags and all seats, instead of including it in their base fee. Plane is tigjt and uncomfortable, no on board entertainment and seats don't recline. Most passengers were drunk and rowdy after long wait at the airport, and a man was busted for smoking weed in the bathroom. And someone else sat in my seat. THE WORST FLIGHT EXPERIENCE I HAVE EVER HAD--an all around disaster."
Cons: "We paid for seat both way. Our returning flight moved our seats so we were no longer sitting together. Had to then go through the check in line ( even though we already had our boarding passes) to have the seat problem resolved. Only to be told that we never purchased seats. I had the documentation of the purchase and was still told we did not purchase seats. Not pleased."
Pros: "The flight arrived 40 minutes early."
Cons: "I paid $40 for a carry on. The plane was not pressurized, I've never had my ears hurt to bad on a plane."
Cons: "I left a bag in the airport, and they did not issue a guest pass to help me retrieve it. While the police and other flight agencies they should issue it. The person at the counter was indifferent, and lazy."
Pros: "Leg room that I paid extra for"
Cons: "Staff very rude, continuously asked if the passengers next to me spoke English even though they obviously did, very uncomfortable chairs"
Cons: "Couldn't move the seat back at all. Couldn't sleep."
Cons: "Every time we fly with Frontier we are always delayed for hours. My husband did not even want to fly with Frontier but i told him this time may be different but I was wrong. Flight was suppose to leave at 9pm we didnt leave until close to 12am. Also, I am pregnant so I was so looking forward to arriving on time and getting food and into bed. (restaurants close at 8 at the Indianapolis airport) Very disappointing will be the last time we fly Frontier."
Cons: "Frontier's computers were down for updates at the same time we were trying to board. They could not get us on board, and we have not missed a funeral of one of our closest family members. This is simply unacceptable."
Cons: "Both times flights were delayed by minor maintenance or paper issues. Seems Frontier is not so efficient at preparing flights mechanically and paperwise as other airlines. Or maybe they had to run to Home Depot for a part. Either way it seemed they should have anticipated the minor issues earlier rather than delay the flight."
Cons: "The flight was cancelled. No big deal. It happens. But the the manager at the ticket desk took two hours to figure out a solution. His "solution" was to print out a phone number, hand it out to each of the passengers and then tell them to call because "there was nothing else he could do for us". And then he left to some back office and didn't come back out. The phone number he gave everyone was out of service. I called the regular customer service and asked them to help me rebook a new flight. They refused and said only the employees at the ticket counter could assist. The ticket counter people offered a refund over and over. But why would I want a 100 refund when I needed to book a 3-400 dollar flight to get to my destination. About eight hours, a couple of yelling matches, getting hung up on twice, and several actual tears later, I finally got a flight booked but the earliest flight they could find was 24 hours after my original scheduled arrival time. I'm writing this thirty minutes into my wait for a hotel shuttle. Long story short, I will take a greyhound or catch a cab or walk to my destination before I ever use frontier again"
Pros: "It was a smooth ride despite the weather in PHL"
Cons: "Flight was delayed one hour, my white luggage got two big footprints on and black marks all over, so they didn't handle my luggage with a little bit of care, waited 26 min at the baggage claim to get my now dirty luggage, there weren't complementary snacks on the plane."
Cons: "I missed my flight because they closed the check-in counter and hour before departure."
Cons: "Charged for every additional thing so the cost of the ticket was not true."
Cons: "Flight left 45 minutes late with no alerts, uncomfortable planes, tray "tables" couldn't hold more than a deck of cards and a small coffee, nickel and dime for everything, no wifi"
Pros: "Efficient boarding, arrived early"
Cons: "Had to pay extra for everything--seats, sodas, bags both carry-on & checked. Seat tray miniscule"
Cons: "They charge for water. WATER. They charge for a carry on. The plane felt like it was going to fall apart. After an hour of turbulence, I started to feel sick but thankfully didn't have to throw up because there were no vomit bags. If you need a really cheap flight and are only bringing a purse, it would be a decent. But be prepared for rude people, discomfort, and turbulence. A misleading, unprofessional company."
Pros: "Plane was newer, very clean. Seats were comfortable and the flight crew was amazing. Pilots were friendly and kept us in the loop on flight time, turbulence, etc. Flight crew was amazing and very friendly."
Cons: "Seats don't recline??"
Pros: "Pilot was excellent. Nice take off, and landing."
Cons: "I had to pay for a carry on, both ways, this added $80 to my flight. I could have gotten a cheaper flight. Flight was delayed due to broken air conditioning that didnt work the full flight."
Pros: "The crew was friendly and the plane was clean. Seats aren't too bad either."
Cons: "This is the only airline I know of that charges for a carry on bag as well as non-alcoholic beverages. Also, the charging for seats is ridiculous."
Cons: "Hidden seat and carry on fees. Come on now. What is the likely hood someone doesn't have a bag flying 2500 miles. You're going to charge for that in addition to the ticket? Plus, yes plus another charge to select a seat. Super dumb and honestly a bit childish. Put your entire price online and let people pick. Also note zero wifi. I know you're a lower tear airlines but it's 2016! Give the people the all in price and if you won't give them entertainment or wifi make worth their wild. Also note, the tray table was about the size of a tablet, I couldn't even use my computer to do local work during the flight. I appreciate the safe flight but from a high level: 1: make your online prices more transparent. 2: if you're going to be lower tear, make it clear that wifi and infighting entertainment isn't included. People will still choose to fly cheap, but to burry hidden charges is horrible."
Pros: "If Kayak wants to boost its website it should give overall projected costs for flights not just bare bones prices. Frontier is the biggest nickel and diming company since Ryan Air. What a disgusting and dubious way to run a business. Worst experience ever. I have had and continue to have status with at least two of the large carriers, so I have flown a lot. Too bad no one else could provide the direct flight to Cincinnati."

Too bad no one else could provide the direct flight to Cincinnati."
Pros: "Easy check in, comfortable plane, friendly staff."
Cons: "Everything is extra. Once you buy your tickets you find out you have to pay for your seat assignment, carry on luggage is $30.00 each way for a total of $60.00, checked baggage is $25.00 each way for a total of $50.00. What really got me was that they charges passengers $1.99 for a cup of water on the flight. Passengers should take this into account when comparing to other carriers."
Cons: "I took off time from work today to catch a 5:25 flight from San Francisco to Denver, arriving at 9:05. It's now 11:55 pm and I am still sitting at gate 21 with a whole bunch of people other waiting for a plane to arrive. My only choices are to wait of this plane to show up, or come back in the morning to take the 5:45am flight. I have business meetings in Denver tomorrow morning. I had a car rented and a hotel reserved. The car rental in Denver closes is 5 minutes. The thing that's the most upsetting is that we keep receiving erroneous information. The original departure time was 5:25. Then we were told 6:00. Then we were told 9:00pm. Then we were told 12:03, Then we were told 12:20. Now we are being told they don't know when the plane will arrive to take us to Denver. I will NEVER fly Frontier again."
Pros: "price of ticket and friendliness of crew."
Cons: "paying for a carry-on and not being told during booking that this would be an added fee. my belt buckle was covered w/ food from a baby or young kid."
Pros: "The staff was very helpful, I needed assistance and they were there to take care of my needs."
Cons: "How the airlines charges for everything except water."
Pros: "Nothing"
Cons: "Service, seats, everything...not worth the cheaper price"
Pros: "Crew was excellent and fun"
Cons: "Overcharging for baggage"
Pros: "Good price, early arrival"
Cons: "Rude service at checkin by Keisha and cabin temperature during boarding was in the 80s"
Pros: "The crew was awesome."
Cons: "Extra hidden fees for baggage, food, and seating. Next time I would opt for the more expensive flight for more comfortable ammenities."
Cons: "Having to pay for seating and for carryons? give me a break. Finding out I had to do so AFTER I bought the ticket was DECEPTIVE and OFFENSIVE. If it was published somewhere on the site, it wasn't Obvious. Not to mention the 90-min. departure delay. That I can excuse."
