Great all around.

Cons: "Nothing--everything was great--perhaps the best service I've ever received."
Pros: "Seats were comfortable didn’t have to pay extra for my personal day crew was polite"
Pros: "Good seat. Good movies."
Cons: "A better range of free food choices would be nice."
Cons: "Horrible experience!!"
Cons: "30 min late"
Pros: "Nothing. I missed this flight because of a delay of my flight on Friday."
Cons: "They could at least announce boarding group 4..."
Pros: "Crew on board was nice."
Cons: "Boarding was very unorganized. I thought families traveling with kids would get priority boarding before main cabin."
Cons: "I paid extra for an emergency exit seat. The seats in the row were visibly different from ones nearby -- the seat padding was gone (felt like I was sitting on a board) and the seat bottoms slanted down producing a feeling of sliding out of the seat."
Pros: "Shory"
Pros: "miserable. Flight."
Pros: "Short flight."
Cons: "No concerns What I expected for a quick flight"
Pros: "great trip and crew"
Pros: "All the service was good"
Cons: "I am handicapped and there was no attendance at the gate once I arrive in Honolulu, no wheelchair assist to help me to the baggage terminal."
Cons: "Seemed disorganized getting on"
Pros: "The flight attendants"
Cons: "The pilot was too aggressive in regards to the take off and landing, landing was way too hard and fast"
Cons: "Rushing from gate to gate after sitting on the tarmac for 30 minutes after not having anything to eat on the four hour flight from PHL. Not being able to get anything healthy because the layover was reduced from 40 minutes to 5. GIVE US SOME FOOD DAMMIT!"
Pros: "Landing and deplaning"
Cons: "Literally everything else"
Cons: "Flight was delayed"
Pros: "Everything happy and in time. Nice staff"
Cons: "Nothing"
Pros: "Not much here. The seats were ok, but the rest of the flight the airline was just poor."
Cons: "The airline is so outdated and behind the times of their competitors, their in that they don't have in flight entertainment unless you download their app and give them your email address. On top of that when I originally booked my flights, I had made sure to have 1.5 hr for a layover between my connecting flights. Well, they decided to move up my connector such that I had 25 minutes to run across 2 terminals. They only give you pretzels on the plane, and a single soda drink. They offer you "food bundles" but why do I want to pay $8 for a sandwich that costs $1 to make."
Cons: "Gate agent told me it wasn't his job to quickly verify if my luggage had made it on the plane after my 10 minute sprint in PHX. I know at my job, I don't get the luxury of telling customers "it's not my job", especially when the customer has had a bad experience with us."
Pros: "Enough leg room. Free movies"
Cons: "Nothing really"
Pros: "Everything was good."
Cons: "don’t know! didn’t get to phoenix because of plane issues"
Cons: "The flight was a bit delayed and was not cleaned at all, may be because of short of time, but minimized the further delay, so acceptable."
Pros: "Arrived early"
Pros: "On time departure and arrival - friendly crew"
Cons: "No own movie screen."
Cons: "Delayed flight, multiple gate changes"
Pros: "Full flight, crew worked timely"
Pros: "Flight departed and arrived on time. Good, friendly, efficient service on flight. Cabin crew took special care to arrange for those with on-going flights and tight connections to be accommodated to make these tight connections."
Cons: "Tight seating and aisles."
Cons: "Essentially a bus ride with the comfort of a wooden bench."
Pros: "Nothing"
Cons: "Waiting on a hot plane for 2 hours"
Cons: "I'm pregnant, and didn't have time before my connecting flight to get food at the airport. I was sitting near the back of the plane, and was ready to purchase food. By the time the cart reached my row, all the food options were literally sold out. I ate the free cookie and had some apple juice, but wanted something with some protein. I guess I'll remember to pack more snacks next time."
Pros: "Seat was comfortable"
Cons: "Gate agent told me my bag would fit under seat but when I got on board found it would not and had to do gate check."
Cons: "Upon boarding the aircraft, the attendant at the gate told me to check the size of my carryon bag against the test dimensions, which I did. My bag fit but I had to press the side in slightly to make it fit. She said it had to slide in without me pressing on it and proceeded to make me remove items from the bag in order to board the plane. I walked down the ramp with my extra pair of shoes and a book in my hands. As a result, I had to place my bag far from my seat due to the added time. My bag easily fit in the overhead compartment with room to spare and my being made an example was a completely pointless exercise."
Pros: "Good preferred seat."
Cons: "Would at least like a choice of a snack instead of cookies I don't care for."
Cons: "Had a passenger behind us that was coughing the whole flight with what we think was a cold and now we are both sick with colds."
Pros: "Flight was on time. Plane was clean. Staff very professional."
Pros: "The price was fair and the flights were on time."
Cons: "Bags cost extra, food cost extra, seats cost extra. My knees were in the back of the seat in front of me the entire flight (two exit row seats were empty) and there was no way to move that provided comfort. The overhead bins were full before half of the passengers boarded. The crew was polite, but not kind."
Cons: "Being led to pay to select seats on flight that was only 50% full"
Pros: "I did not like anything about the flight to be honest. Oh wait you did have cool club lights that were blue that tried to distract me from the fact that I had to take an American airlines flight."
Cons: "Holy moly. You know if you stopped charging extra money for checked baggage you wouldn't have a ridiculously annoying amount of customers with too many bags for overhead storage. Then you wouldn't have to threaten your customers to store their small bags under the seat. Then I would have room for my feet under the seat. When I would have been comfortable. I also wouldn't have to annoy my neighbor with trying to move and get comfortable. But instead the exact opposite happened and I'm offended you guys have America anywhere near your name."
Pros: "See above. Worst flight in 60 years of flying.Their systems failed at every point-- changing flights without carrying over seat reservations "Too close to flight time""
Cons: "Attitude of many employees--" tough on you, suck it up. stuff happens". poor communication re flight change, rejection of AA Advantage Mastercard to pay for baggage check and get boarding pass and seat assignment. Rerouted me by 200 yards to TSA checkpoint I could see was 30 yards away. When flight arrived in SFO the arrivals board never showed it and there was no carousel shown for checked baggage. I finally had to go to customer service, where attendant just pointed to my bag on the floor with lots of others from the flight, shrugged, no apology, and chewed her gum a little faster before turning her back."
Pros: "Same as above."
Pros: "Timeliness"
Cons: "Nothing"
Pros: "Excellent"
Pros: "There was no warning until departure time that flight was delayed for two hour. Some other american flights were delayed much as four hour or more."

It was very cold on the flight and where I landed.

Too many announcements. There was no food or entertainment but there was no n/a option

Cons: "Clean the plane prior to passengers coming onboard. The plane was dirty in between the seats and food particles and crumbs everywhere. It seemed like they did a half cleaning job and a little more effort could go along way. Since beverages aren’t included and the seat do not recline. Other than that the flight was smooth taking off, in flight and landing. Thank you to the pilot for his efforts."
Cons: "I was bumped from the flight I booked 3 weeks in advance because they over booked, and frontier made me pay 120$ to catch the next flight which was not nonstop, and added an 8 hour layover"
Cons: "Have plane depart on time."
Pros: "Ok time"
Cons: "Frontier charges for absolutely everything, and the chairs are very uncomfortable, they have hardly any padding and don’t recline"
Pros: "Crew was very nice"
Cons: "Better off paying more upfront with any other airline. As tickets will end up being same by the time you finish paying for luggage and your seat. Not worth the hassle and discomfort"
Pros: "Everything else was fine."
Cons: "The flight was delayed 30 mins prior to boarding for 6 hours. They were missing a part that needed to be ordered. What I don't understand is why they couldn't have emailed everyone to notify us so we weren't stuck in the airport for 6 hours."
Pros: "Nothing very disappointed with Frontiers service"
Cons: "From Ontario to Austin we were charge $50 for each carry on luggage we 1 for me 1 for my husband total $100 charge From Austin to Ontario carry on luggage was free why?Im filling complained about the airline"
Cons: "We arrived very late due to the airline being run so poorly. Something about paperwork according to the pilot. Now the rental car company is closed so I have to sleep at the airport and wait till the budget opens again in the morning. Frontier should put me up in a hotel as their mismanagement caused the delay not the weather. But they just said too bad because the flight was less than 4hours late. Frontier - never again!!!- plus the seats are painful"
Pros: "I liked that the staff was friendly and the tickets were affordable"
Cons: "I didn’t like that there was no complimentary food or beverage options."
Pros: "We appreciated the cheap airline ticket prices."
Cons: "We were outraged by having to pay $45 for each piece of luggage, including carry ons! After these hidden fees, our tickets would have been cheaper for a well established and popular airline."
Pros: "It didn't crash"
Cons: "The whole staff from the check in to the attendants was rude rude rude. Never again!"
Pros: "Easy ticket booking"
Cons: "Price can be still reduced"
Pros: "expeditious boarding, low fare"
Cons: "bad seats they do not recline of a 3-plus hour flight, no snacks or drinks without charges,"
Pros: "Flight prices"
Cons: "The delay then missing my connecting flight."
Pros: "Flight finished trip early"
Cons: "Everything costs extra. What's the point of saving $40 on a ticket if you have to pay $80 round trip for checked bag. Older plane. No drinks or entertainment."
Pros: "Crew was pleasant enough. It would have been nice to have been offered free water on flight."
Cons: "I questioned the mechanical condition of the plane, while still on the ground. The plane made some strange sounds before taking off. Seating space was confining. I did not like all the "nickel and dimeing" while booking flight."
Cons: "Frontier personnel at the ticketing refused to print out my airline ticket and allow me to try and catch my flight because we had not checked in 35 minutes prior to flight departure. I missed the flight and had to eat the price of the ticket and find another airline to get to my destination. There was plenty of time to have made it through TSA and boarded the plane but because of some ridiculously stringent policy they would not allow me to try."
Pros: "Flight was very quick and the crew was totally awesome!! Food and entertainment got a one star because the was no food or entertainment. The flight was too fast. I'm sure that would have been 5 stars as well. (Should have a NA option)"
Cons: "Nothing. This flight was flawless!! The plane was clean and the service was great. This was a great flight from Phoenix to Colorado."
Pros: "I liked the price, It was a last minute flight to see my mom before her surgery. The boarding was smooth. The cons though were the tiny seats from the 1970's and that even a coke, water and/or snacks were for sale and not complimentry."
Pros: "Arrived on time"
Cons: "Crew yelled at child for trying to carry on skateboard, cost of carrying on bags, no free food...or even water, charge to guarantee you get to sit w family. Up front cost does not represent what you'll "pay"."
Pros: "went from point A to point B, that's what I paid for and that's what I got"
Cons: "seats were uncomfortable but what can you do"
Pros: "I really like the newer seats on Frontier. They are comfortable and roomy. I imagine at spring cleaning time, the seats are so much easier to clean. Don't know if airlines do a spring cleaning. LOL"
Pros: "Good nonstop flight. Flying out of a smaller airport was great. Not a "frills" flight but got me where I needed to be at a very reasonable price. Will be using this flight to go back and forth often."
Pros: "Average flight, nothing special, nothing to complain about."
Cons: "Late, staff seemed disgruntled, no water offered on either flight and both times were on the plane over 4 hours. Seriously, no water? Sad. Won't be flying Frintiere anymore because the tickets might be cheap but they upsell and charge for everything and the service is not good. The same as Spirit. Sorry guys, you lost my patronage!"
Pros: "In spite of weather delay, boarding, crew and flight were good"
Cons: "Surprised at how much we were nickel and dimed. Carry-ons cost $45 each. Checked bags cost $40 each. The crew seemed apathetic and exhausted. We were delayed an hour then sat on the runway for another hour before departing. No explanations were given either in the terminal or from the pilot. We will try very hard not to fly Frontier again if we can at all help it."
Pros: "Flight was canceled and I was not notified. Flight sat on tarmac, unloaded and then canceled"
Pros: "My 15 year old hasn't even boated her flight as it is delayed until 2:33 am. She was to leave PHX at 7 something this evening. Disappointed with Frontier-will not use this airline again nor recommend to family, friends nor clients."
Cons: "The line to checkin for flight was very long (not enough employees). We were told to go to Gate 20, then told to go to another gate along with two other flights. Waited for hours with no information as to what the problem was or when the flight would leave (same for other two fights). There were no Frontier employees in the terminal to be found to ask. It was all very unorganized! Finally one employee made an anouncement that we had no flight crew. Again waited in line for hour and half to talk to the one employee working the desk. Then waited almost two hours for bag at baggage claim. Still did not get luggage. Had to pay to stay in hotel and book flight on United the next day. When I tried to ask a Frontier employ the next morning where I should go to find luggage he was extremely rude and said I had to wait in line with a bunch of other people trying to check in and others that were on a flight that was just cancelled. There is not baggage offfice like other airlines have - they are too cheap!!. Their fairs are cheep but they nickle and dime you to death with baggage fees and seating feas, seats are cramped and uncomfortable, employees (the few they have) are rude. I think the airline is extremely cheap, unorganized and pathetic. By the way, i filed a claim on my luggage on line as directed by the recording you get when you call (because there is no one to talk to) and now received an email that I need to file claim with the baggage office at the airport. What baggage office??????"
Cons: "Every time they delay in flight this is happened 20 days before on same flight"
Pros: "The woman at the check in counter was nice"
Cons: "All of it. Horrible seats that are so piled on top of each other that I felt like cattle; nickel and dining us every chance you had; poor communication via email and text that the flights are delayed; HORRIBLE customer service online and via phone (I'd rather talk to Comcast than Frontier); no wifi or entertainment on the flight, which for a 2.5 HR flights is rediculous. One of the worst flight experience ever."
Pros: "Crew was nice. Plenty of overhead space (probably because people don't want to pay to bring on a carry on anymore... so the negative lead to a bit of a positive)"
Cons: "Seats are SO UNCOMFORTABLE!!!! I don't know what they have against the human body, but the new seats have no cushion, no lumbar support, no neck support and there's not enough leg room. I know they want to save money and offer cheaper ticket prices, but I don't know why a seat has to be rock hard in order to make that happen."
Cons: "The return flight was delayed and there was no one there to let us know. We had to go online to figure it out."
Cons: "Having to pay for everything individually. The cost for our bag it way to much. With other airlines we get free coke products and little bags of pretzel. But with frontier we have to pay. Y'all are my last choice for flying"
Pros: "Price"
Cons: "The same 2 screaming babies entire flights. Attendants allowed with no assistance."
Pros: "I like the fact we landed safe."
Cons: "I didn't like the that none of the worked knew how to communicate with customers. I think the workers should be taught the concept of customer comes first."
Cons: "My bag is still missing i don't have critical medication and I can't even get customer service to answer my calls"
Pros: "Not impressed at alll"
Cons: "Flight was delayed twice , seats and leg space very uncomfortable"
Cons: "The charges associated with the flight. No one should be charged for a carry on and for a seat after they have already purchased their ticket, it's ridiculous. I will never fly this airline again."
Pros: "Absolutely nothing"
Cons: "Wanted an AM flight...got to the airport to check in 6:30 am to find out I had booked a 8:05 PM flight....so we had to book a fly another airline."
Pros: "Even after a 2 hour delay on a 7am flight, no effort was made to board the plane any faster. Staff appeared uninterested in customers"
Cons: "Frontier is not a customer friendly company!!"
Cons: "A word of caution to anyone flying Frontier airlines. Carry on bags cost $40 each way. Even checked baggage is cheaper at $35. Don't forget to add the extra $70-80 when you see the tickets slightly cheaper online. Plus, it will cost more to select seats to sit together and even the snacks/drinks cost money. I'm shocked I didn't have to pay extra for a pilot."
Cons: "Flight was five hours late due to maintenance problem. This could happen to any airline, but is apparently not at all unusual for Frontier. They did give vouchers for dinner at the airport, but continued to charge for even water once on the plane. Frontier prices are good, but not worth the hassle to me. I will choose Delta or American next time."
Pros: "The time of the flights, and the quick security at the terminal."
Cons: "Hidden fees for everything. You book your flight for one price. (mine was about 100$ less than other airlines at time of booking) -Then they have you pick your seat (charge) -Then if you want to check a bag (charge) -Then if you want to BRING A CARRY ON (CHARGE) It ended up being way MORE than the other flights I could have just booked on other airlines. (I booked at $220.00 and by the end of my trip spent $373.00 with Frontier) Also, the returning flight was delayed 45 minutes but I received no notifications."
Pros: "I really liked the tickets prices and the boarding was fairly smooth."
Cons: "I understand there is a trade off for the lower price fair but $40 a one way for your bag is a bit much. The crew largely were not very engaged with the passanger. I all but had to rais my hand and shout out to the attendant to take my order - the passanger next to me had to say something to the attendant on my behalf. I get people at one point or another have an off day - but it was bad a Ly the same on the way on second leg f the trip"
Cons: "I don't like paying for my seat or a cup of coffee. Hate paying for my bags, yes, even the carry on. Just give us honest fares and make it a nice trip - you're going there anyway, right?"
