Cons: "I checked two bags and paid for them. The flight was full. I dutifully got in line for zone two. Next thing you know, at least 25 people got to board early and have free bag check. Really? I should get $35 dollar refund."

Cons: "The crew didn't even have the decency to wait for passengers to deplane. They were long gone by the time we got off. I found this pretty terrible service.

Pros: "Nicole and I really like the Economy Plus seating with the extra legroom. It is a good compromise between sitting in cramped Economy seating and spending way too much money in Business Class."
Cons: "I wish that the Seattle Tacoma Airport has an Admiral's Club Lounge. Actually, I might as well fess up... I wish that EVERY airport had an Admiral's Club Lounge.

Pros: "The crew was very friendly with our girls and accommodating with switching around our seats so we could sit together."
Cons: "There weren't any screens, which surprised me since our 3 other flights had them, and we unfortunately didn't have a backup plan. Our kids were disappointed. Also in order to sit with our young children we were only given the option to sit in the very last row that doesn't recline which was difficult seeing as the flight took place in the middle of the night according to our bodies. No actual food was provided despite it being a 6 hour dinner time flight."
Pros: "Everything was great, but they didn't serve ANY complementary food on a 5 hour flight. What happened to lunch?"
Pros: "Nothing. Someday the airline industry will be disrupted and we'll all remember this and say, "can you believe what we used to put up with, and how expensive it was?!""

Cons: "This WAS the worst flight I have ever been on! First no pilot then no gas. Then turbulence the entire flight basically. AND THEN when we landed we couldn't even get off of the plain because there was no one to help us off??!!! Also they were out of food. It was just over all horrible."
Pros: "He enjoyed everything about the flight it was comfortable the crew was excellent he met nice ppl thank you for the safety and class."
Cons: "Despite arriving more than an hour ahead of time, I had to wait in a long line to get to the ticket counter and by the time I got there the assistant refused to check my bag. I then had the choice of catching another flight standby, possibly not even arriving on the same day, or changing my ticket for an obscene amount of money. I hope to never deal with AA again."
Cons: "Flight was late. More than doubled my layover time"
Cons: "The captain announced that the flight crew exceeded 9 work hour per day due to the takeoff delay so the passengers were forced to sit and wait in a stuffy stationary aircraft for 2 hours prior to takeoff until a different crew could arrive to service the flight."
Pros: "In-seat entertainment options. Good system, easy to use, lots of good options. Why couldn't you have had this on our flight from Europe?"

Pros: "I got home"
Cons: "No tvs"
Cons: "They cancelled the flight and put me to fly the next day"
Cons: "Charlotte to Seattle flight: The food served in first class smelled awful. Seated in premium seating just behind first class was unfortunate due to the atrocious odor that lasted for 3+hours. There was no option for food service for the rest of the plane. Which was unfortunate as I was very hungry. Due to inconsistent notification that the plane was delayed / on-time (kept switching the notification) we opted to not get dinner in the airport..... To which the plane was was an hour late yet we were told to check in every ten minutes to see if we were boarding. There were no blankets. The plane was incredibly cold. The suggestion I received from the flight staff was to turn off the vent above my head (which I had already done.) I had brought a jacket and was wearing pants. On a 5.5 hour flight, the crew served beverages 45 minutes into the flight (per usual) and handed out a pretzel pack. They didn't come back through with water or beverages again. On other airlines, they promote water at least once an hour to keep swelling and dehydration down. Since I am a pretty frequent flier, I bring my own water. Still, coffee would have been nice. Suggestions: increase beverage service to at least twice / 5.5 hour flight and provide blankets upon request. Food choices and entertainment would also be good. Don't cook stinky dinners in first class and allow it to pollute the rest of the plane."
Pros: "Unable to Rate food & entertainment (night flight) I can, however, rate comfort since it was the worst crammed in seating ever!! They talk about the increase in violent behavior. Perhaps American Air could step up to the plate and offer a bit of comfort for hard working passengers. How? Easy to figure out!! Give us leg room for crying out loud."
Cons: "Crammed seating... No leg room.... Volunteered to check carry on... (Big mistake) had a longish wait for bags.."
Cons: "Broken seat and terrible gogo video experience with an attendant crew that was dysfunctional together for food/beverage service. I prefer to not fly AA."

Pros: "Everything was great"
Pros: "I was asleep."
Cons: "The seats were very cramped."
Pros: "On time flight"
Cons: "Gate agent at SF was rude and unprofessional. While waiting, gate agent at gate 65, flight 647 started the following, “group 1 boarding, group 2 boarding...everybody, let’s go let’s go”. She went on to call out one, Hispanic customer with limited English, “come here, you can board now”, rude rude."
Pros: "The crew was so polite and helpful."
Cons: "Nothing could be improved for this short flight!"
Pros: "Very kind crew"
Cons: "Flight was delayed by 2 hours and all they offered in the flight was direct tv - inflight app entertainment did not work. Also had to walk off the plane after boarding to gate check my bag. So disappointed."
Pros: "Nothing."
Cons: "They delayed our flight 4 times, over 4 hours, told us the flight moved to a gate that didn’t exist, gave us erroneous information about alternate flights, assigned 3 different planes that needed maintenance, and then we waited over 2 hours to talk with a supervisor. I finally had them rebook me on Alaska Airlines (the best)."
Pros: "Crew"
Cons: "Comfort of seats. Too close together."
Pros: "Snack menu, the plane was moderately clean compared to the last. Good communication about late flight."
Cons: "Staff was mostly rude, tired. The plane was 30 minutes late due to weather. Internet would not work, the captain kept trying to reboot it, no entertainment. An older plane in moderate disrepair. Economy seats were much more uncomfortable than American Airlines."
Pros: "Nothing."
Cons: "Everything. I will never fly with United again. I will pay more money for another airline which respects people and their money."

Cons: "Delayed"
Pros: "Everything was great except for the food."
Cons: "The hamburger bun was hard as a rock."
Pros: "Free entertainment."
Cons: "The flight was incredibly hot the whole way. Which the flight was 5 hours long. The crew was a little rude, not to me in particular but to others. They didn’t have a good attitude. Sat at the gate for an hour waiting for other planes to come in so that other people wouldn’t miss the flight. But an hour??? Really!! People were getting mad and hot and sweaty. Food wasn’t cooked all the way when it got to a passenger. It was still cold. It was the worst flight I’ve been on. I would rather ride in a jump seat on a C-130 with military!"
Pros: "Ontario airport is so easy and convenient"
Pros: "Very smooth fligh and very friendly and helpful staff"
Cons: "The seats were extremely crammed and there were no movies or shows without purchase"
Pros: "It was a short flight"
Cons: "I didn’t like not having to choose our seat assignments after we booked our flight. I have used Kayak on many occasions and I was able to choose my seat after booking. I was not able to do that after I booked my flight."
Cons: "Seats are very uncomfortable the delay was unexplained and no information was givenuntil we boarded the plane"
Pros: "i was rebooked and am still on my way"

Cons: "This flight was also late, and this was after having to spend the night in the airport"
Pros: "Staff was friendly and helpful"

Pros: "Crew were friendly and helpful"
Cons: "Seats are very tight. Entertainment depends on bringing your own ipad or laptop and using the United system. Movies tended to be oldies. Food is 10 pretzels. Count them."
Pros: "The aircraft"
Cons: "Crew delay"
Pros: "Overall the flight process was fine."
Cons: "Kayak is not transparent enough about highlighting which flights are low cost flights during purchasing. I thought I was purchasing a regular fare where I could bring a normal carry-on onto the flight, but this was a low cost flight and I had to check my bag. This information was not disclosed until after payment, and I believe this is dishonest on the part of Kayak. Kayak needs to be much more upfront about the details of the flights so that we passengers can select flights according to their needs. I felt deceived by the fare and would have purchased a different flight if I would have known ahead of time."
Cons: "No wifi... with the amount you pay for the flight, seems insane you have to pay for wifi too"

Cons: "Very Rude while talking to me at the airport. Was not happy to assist me and other passengers even though it was the air-line mistake for cancelling the flight and delaying the flight. Will never fly with this airline ever again."
Pros: "No charging docks on plane as military duffle bag open with clothing hanging out on arrival ~ not sure if anything stolen but the threat is very real and it's unacceptable for military bags to be delivered in that manner"
Pros: "What did I like like that the pilot let us know what was going on on every moment and the stewardess was very friendly"
Cons: "Seats very uncomfortable last flight 30 minute flight took an hour if not more and not knowing what gate my next flight is until I get there"
Cons: "The plane landed to San Francisco earlier than scheduled, but we could not get off the plane due to the gate not available. We were stuck on plane for about half an hour and I really worried about making my connection. I hope such arrangements are conducted more smoothly."
Pros: "nothing totally a rip off"
Cons: "I paid 125 for my hockey bag. Flight was delayed but no email or anything. Changing my flight was miserable staff so rude and people on phones can barely speak"
Pros: "I was moved to business class after an ordeal but the extra room was nice."
Cons: "I came down in a wheel chair and noticed my ticket had me in an exit row. When I asked to be moved, the women behind the counter had an attitude. Many of the customer waiting to board noticed. Next she started boarding the plain and I had 3 people ask if I needed to be pushed down and they would help. She barked at us that someone was coming. Once inside I asked for help getting my plug into the outlet because I wasn't able to make it fit. The crew member told me to keep trying. Because I never could get it in, my computer and phone wouldn't work. So I figured I would purchase one of the entertaining units but none was offered. It made for a very long flight. When leaving the plane, the other crew members were very helpful and even the wheel chair attending me was a delight. I was on flight 1977 from Houston to Seattle on November 7th. I usually fly twice a month for business. After my ordeal, I will use other airlines."
Pros: "Prebording was helpful being disabled and having a service dog, crew was very helpful, and it was much more comfortable having the extra legroom as requested in advance and having it honored."
Cons: "I did not enjoy having to pay for even the most basic entertainment."
Cons: "This flight was delayed for 1.5 hours which was not nice and it was a six hour flight and only could receive pretzels without paying for food."
Pros: "Crew was gracious, helpful, and courteous during a terrible and disruptive ordeal for passengers"
Cons: "Being stuck for nearly an hour sweating on a plane with no AC while mechanics were trouble shooting, only to find out that we had to exit the plane, and that it could not fly. Passengers had no idea what to do - whether another plane would be sent for us, whether United would reimburse our ticket if we arranged another flight on our own, etc. We were left to fend for ourselves. I had a wedding to get to with many pre-wedding events, starting this evening. So, I looked for another flight, found one, booked it, and went to United customer service to request reimbursement for my ticket. I was told that United had just learned that another plane was coming for us and would arrive in 30 minutes, at 8:10. (My original flight had been at 6:35). The other flight I had booked was at 10:30 pm. So, United customer service changed canceled my new booking and put me back to my original flight, now arriving at 8:10 and boarding at 8:50. The plane did arrive, but we did not board until 10:50 pm. My flight left at 11:02 pm. Bottom line is that my flight was delayed 4.5 hours. I missed an important event that I was supposed to host. I missed my only opportunity to see a dear friend (and guest of honor) - this is someone I have not seen in person for ten years and was the guest of honor at tonight's celebration that I was supposed to host and missed. Furthermire, I could not carry on a bag that I have carried on for years, and that would have easiky fit. Having to check my bag left me without my phone charger. Of course, the fact that we were 4.5 hours delayed meant that I ran out of power shortly into our long flight from Washington. to Seattle. And the food was awful - stale nuts, . ;, b:;"
Pros: "Polite staff"
Cons: "The boarding process was chaotic. Overhead bins were full, but flight attendants were not available to help people struggling to find a place for their baggage. They should've offered to gate check baggage"
Pros: "Flight Attendants were nice."
Cons: "The flight was expensive and they wouldn't let us or anyone place carry ons in the over head bin. It was an expensive ticket and didn't include checked bags ($25 more). Carry-ons wound up being "stowed". It would have been nice to know before I bought the tickets that I needed a smaller carry on."
Pros: "Flight crew was attentive and kind."
Cons: "We had to sit on the Tarmac for 20 minutes before taking off due to low cloud cover over Seattle."
Cons: "The delay ruined our evening and made the expense of a hotel for the night and babysitting moot because we might as well have flown the next morning. So much for seeing friends in Seattle on Thursday night. A 2 hour delay means we just get to sleep in an airport hotel for no reason."
Pros: "Aircraft, flight (except for late arrival at gate) and service"
Cons: "Pilot announced we would arrive early in Seattle. When we go to Seattle we waited 30 minutes for a gate and actually arrived late. When we got to baggage claim we had no claim area posted for our flight; another 15 minutes waiting to find out where our luggage would be"
Pros: "Everything listed above is accurate of the 1st flight. I had just as much leg room on the 2nd flight as the first with it being even more crowded. Doing well!"
Cons: "Nothing comes to mind that I would be willing to say anything about."
Cons: "They over booked my flight, so I would have missed it had someone not gave up their seat for me. This was extremely disappointing begin that I had booked months in advance. I even picked my seats!"
Pros: "Everything went smoothly from arriving to the airport to landing and getting my baggage."
Cons: "Delays caused missed connections in not directions and terrible rerouting plus lost luggage"
Pros: "I liked that the flight, a red-eye, got me to Cleveland safely and on time. There is water for survival purposes."
Cons: "Everything except the above. The seats are awful, there's a "ledge" and not a tray. No reclining, no sleep!"
Pros: "Definitely can't beat the price, especially for a non-stop flight halfway across the country. I had plenty of room in my seat even with my backpack under the seat. The drink and snack selections are pretty decent."
Cons: "Delayed to start and it took a while for all the bags to be loaded. Once we arrived it took over an hour from the time we touched down to when our bags arrived at the baggage claim. Ended up finally leaving the airport an hour and a half after the time I was originally supposed to arrive."
Pros: "I got to my destination in one piece"
Cons: "By the time you pay for your luggage it’s the same price as another airline with comfortable seats more amenities, an actual gate to board the plane vs stairs on the runway,it wasn’t in the main terminal and there weren’t many options for food, the terminal was to small for the amount of people and the plane was delayed coming and going in both directions 6 days apart."
Pros: "Crew was awesome ! The flight crew I would fly with anywhere, anytime. No mucking around ,get in , buckle up, we’re outta here . I love that ."
Cons: "I’m 6’2” , any vehicle other than my R1 is just not super comfortable. Even my truck and i love my truck . But anything over 2 hours starts wearing on my long legs . Thats my issue . Nothing any airline can do for that . I prob need to opt for 1st class next time n see ."
Pros: "Early, friendly staff"
Cons: "No WiFi"
Pros: "Boarding was fine ,no food or drink And charge for small carry on luggage $50-I don’t like it"
Pros: "Seat was okay. Flight Crew was okay. I got where I needed to."
Cons: "Either Frontier or the third party I purchased my ticket through on Kayak (Kiwi.com) sold me a ticket as if it were a complete flight from point A to B with a layover in between. In reality however, it was two totally separate flights which required me to go to the Frontier ticketing counter upon my arrival at my layover destination, get a ticket printed for my second flight, pay to recheck my bag a second time ($45 x2 = $90 which was total BS), go through security again (also BS) only to walk back clear to the other side of the airport where I just was. To top it all off, our flight took off late and upon arrival we didn't even have a jet bridge available. So, all of the passengers had to get off on the tarmac and wait to be bussed from wherever we were all the way to the main terminal. Then they switched the baggage claim caracul on us. What a mess. This will probably be the last time I buy a ticket on Kayak, Kiwi and possibly even Frontier."
Pros: "I arrived."
Cons: "It was an hour after boarding before take off. Another 15 minutes on the ground after landing waiting for a gate at midnight on a weekday. I understand that circumstances occur beyond the airlines control, but this has been routinely occurring on my trips with Frontier. Absent compelling reasons, I will not be flying with them again."
Pros: "The crew were kind and efficient and the planes were clean and well maintained."
Cons: "No entertainment on the flights, but that is to be expected for the price."
Pros: "They still pick up trash!!"
Cons: "New airbus has even LESS room!! Have to manhandle your personal bag out of the even smaller space under the seat! A soda is $3! There is Nothing to read anymore and the crew are overwhelmed with cranky people... making them cranky."
Pros: "I liked that there were no issues with my flight I was able to just board , get there and have no problems"
Cons: "I don’t like the fees for everything. It kinda just made me annoyed that there were fees attached to everything that doubled the cost of my flight."
Pros: "As above."
Cons: "As above"
Pros: "It didn't crash"
Cons: "The whole staff from the check in to the attendants was rude rude rude. Never again!"
Cons: "The carry on price and a kid crying the 2 hr flight"
Pros: "Low fares Smooth ride/landing Bigger leg room than Spirit Airlines"
Cons: "Delayed flight Seats were not the most comfortable"
Pros: "customer service rep was very kind on the phone and was able to give me a full refund for the original cancelled flight."
Cons: "had to cancel and purchase a 2nd same day flight which was extremely expensive. also was not aware that i would have to pay for a carry on bag or purchase a seat placement in advance. was extremely misleading."
Pros: "Efficient from the crowded baggage check to baggage claim. Great Job!"
Cons: "Seats don't recline, get what you pay for!"
Pros: "Flight attendants helpful and pleasant"
Cons: "Plane was filthy. Crackers, chips, etc all over the floor. Wasn't a clean spot anywhere. Unpleasant to sit for several hours with my feet in filth and to have to put my bag in it under the seat."
Pros: "flight was early boarding went smoothly"
Cons: "that you have to pay for a carry on bag that the person checking tickets shamed a person who confused the two Washingtons, DC and Seattle at 530am by repeating their mistake and telling everyone else to not make the same one."
Cons: "Flight was cancelled 30 minutes prior to boarding with no explanation given. There were no other flights on Frontier for two days. There was one single gate agent responsible for dealing with every angry passenger. I had to rebook on a different airline for the next day, and it cost me $250 more. This was very painful, especially during the holidays."
Pros: "I liked that the flight was cheap."
Cons: "That they forgot about 20 peoples baggage in Denver and the day revolved around baggage. I got my baggage later on that night but i had arrived in the morning and if that was the case of me going back and forth to the airport i might as well should have gotten a later flight for that matter."
Cons: "pay for seat on aisle, pay for soda, pay for reclining seat, pay for carry on luggage, reading lite out, no reading for a 3 hour flight, not much in-flight service."
Cons: "Not sure why there even is a flight staff. Airline doesn't even offer snacks. Airline did one round of "beverages" on a 4+ hour flight. The in cabin crew hangs out in the front just chatting with each other (because they presumably have nothing else to do). $40 to put a bag overhead. Seats don't recline at all."
Pros: "The price"
Cons: "I was flying to Seattle with my 8-year old son and my boyfriend. Because Frontier charges so much for bags, we packed all of our stuff into one bag. My bag ended up in San Diego instead of Seattle. I was told they'd refund my baggage fee and I've yet to see the money. We only had ONE day in Seattle before we were going to drive back to Denver. Our one day in Seattle was ruined because of my bag getting on the wrong flight. We were told the bag would be on the next flight to Seattle, which would be 10am the next day. I was told they would call me when the bag arrived. 11am came and went and I spent 20 minutes on hold just trying to speak to an actual person to find out where my bag was. Finally got ahold of someone and they couldn't locate my bag. We decided to go about our day, but I had to spend $100 on jackets and clothing and toiletries for my son, boyfriend, and me. Around 5pm I called again, and also had to wait another 30 minutes to talk to someone. They told me my bag had just arrived, and sorry it didn't make the earlier flight. Now the Frontier counter was closed and they'd only open from 9pm-11pm. Had to make a 30 minute drive to the airport at 9:30pm to retrieve my bag. All around it was a terrible experience and our one day in Seattle was ruined by the bag getting on the wrong flight. Extremely disappointed in how they handled the situation. I don't care how cheap Frontier flights are, I will not be flying them again."
Pros: "The crew were never short or rude at least."
Cons: "Poor handling of delay. Announced a maintenance problem, due to bird strike, which itself is understandable and I certainly wouldn't want to have that rushed, but at one point they said it would only be another 10 min. Ended up being something like a 5hour delay. They wouldn't just tell us it was a significant delay, but instead kept announcing "any minute now." Offered food vouchers eventually, but many of the few places we could use it were closed by then. Stranded in the airport."
Pros: "Nothing at all really..."
Cons: "Flight schedule kept changing at last minute. Seats were uncomfortable. They charge $25 for every bash to checkin including first bag. Also they charge anywhere from $9 to $16 each flight for picking seats if you want to to seat together with your family. I will not travel ever in frontier airlines ever nor recommend it to anyone."
Cons: "The flight was over an hour delayed on the ground and then my luggage is still completely lost. The customer service has been absolutely terrible. I am in a city in which I do not live, with absolutely no clothes, toiletries, shoes etc and I have been on hold waiting to talk to someone about my missing bag for over 45 minutes. Frontier has absolutely no idea where my bag is, it is not in the place that I took off from and definitely not at my destination. This has been an absolute nightmare in which they offer you pathetic $50 to make up for the over $3500 I have in missing belongings."
Pros: "Flight was on time"
Cons: "I haven't flown frontier for about 7 years. I used to love the airline but didn't realize they had changed their model. I was so surprised we had to pay for EVERYTHING even a carry on bag. The seats were uncomfortable and didn't recline. There wasn't a real tray table to do work, you can't get any sort of beverage without paying. I felt nickeled and dimed the entire time. The crew were not very friendly. Also, I was given a $10 voucher by frontier and I asked 3 different employees how to use the voucher and no one knew. Additionally, the frontier website and check in process is not intuitive and very lengthy and frustrating. I would gladly pay more to fly ANY other airline but frontier in the future."
Pros: "Nothing"
Cons: "Everything"
Cons: "Charging for carry ins makes me never want to fly frontier again"
Pros: "Nothing."
Cons: "The added fees are ridiculous. First we are charged for our seats upon check in. Ugh. Then, we were able to bring our small roller luggage at no extra charge from Seattle to Chicago. However, in Chicago, we were told to pay $60 (PER BAG!!!) to bring them with us, which I think is exploitation because looking back, i wonder if they could have gone underneath in storage at no charge. Also, the inconsistency of fees was VERY frustrating. Plus, $60 for a bag is absurd, what a completely ridiculous number. The seats were incredibly uncomfortable. This is the most economy airline I've ever flown, and it was horrendous. I'm surprised these even passed code, the tops felt like metal bars and barely any padding. I felt unsafe in the case there were to be an emergency. I will never fly Frontier again, and I will always warn people about flying this carrier. Nothing good to say."
Cons: "Frontier canceled my return flight And could not book me on the return flight until two days later. They have no partners or affiliates, so they couldn't even book an alternative return flight on the same day ."
Cons: "$80 dollars in hidden fees, they charge for cary on, and there was no indication of that when i purchased my ticket"
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: "I didn't like anything about frontier. It was horrible."
Cons: "I did not like the seats as they were uncomfortable and did not recline. The tray tables were tiny. The price is deceptive as you have to pay for checked bag, carry on, and a decent seat. The inflight refreshments were not complimentary. Everything had an additional price!"
Pros: "Left late but made up some of the time. Staff were nice."
Cons: "Left late, then sat on the tarmac for almost 30 mins to take off. Cramped again and not happy about the extra fees (see above)."
Cons: "The online check in was a bit complicated and not really clear if we could use e boarding pass."
Pros: "Crew were courteous"
Cons: "Seattle to Chicago: Had to wait "two hours' before flight to check our baggage in. Made getting to the air port "3 hours early" as recommended by their email alert to avoid long TSA lines - which weren't - made us waiting in the airport way too long Chicago to Seattle: Same "3 hours prior" alert (the lines again were not long) made getting to and waiting in the airport way too long. Plane was delayed getting to gate and/or they brought a "new" plane in - and had to wait to get it "cleaned up" since the agent at the desk was the only one on duty, she said. Plane left late, sat on taxiway and returned with a "sensor warning" that needed looked at. Left way late in the end."
Cons: "No TSA Pre-check even with my Global Entry card $45 fee for carry-on luggage (each way) $16 seat selection charge (up to $55 per seat per ticket) No complimentary soda / crackers (only water) No entertainment onboard Told that the ticket I purchased was a 'low fare' ticket which didn't include ANY luggage, not even carry-on Charging more for carry-on luggage than check-in luggage (there is no labor on the airline side for carry-on, but they made it more expensive for the Customer because they'll generate more revenue)"
Cons: "The seats are amazingly uncomfortable. Your ticket price is good , until you realize you pay extra for absolutely everything."
Pros: "The crew"
Cons: "Seats are hard and i wish i knew ill have to pay for a 2nd bag before..."
Pros: "In order to have cheap fares, Frontier charges fees for EVERYTHING. Carry-on luggage, anything besides water, etc. If you can fit everything you have into a small backpack and bring your own snacks, no big deal. If not, I'd recommend a different 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!!"
Pros: "The fellow that checked us in and helped us with checking the bags was a nice person."
Cons: "Having to pay extra for all bags -- Having an hour delay because the pilot didn't arrive on time very uncomfortable seats. Don't expect to ever fly Frontier again!"
Cons: "Crew was pushy about purchasing credit card and got testy when questioned about any benefits."
Cons: "Very unhappy that my price listed on kayak did not include the additional cost for a seat."
Pros: "I arrived in one piece at about the correct time. I liked that the families with babies seated all around me could get inexpensive enough tickets to fly, and that there was an option to fly out of Denver late afternoon."
Cons: "I very much disliked: The $40 carry on fee (web said $25) for a bag I have put under the seat on several other airlines, the overflowing line to check in a bag, the late-start all-aboard loading when I had Zone 1 for boarding, the very uncomfortable seat, the bounce me till I vomit ride without a vomit bag. For once the TSA line was better than the flight and TSA was not good. Frontier has mad my no-fly list"
Pros: "Great price for direct flight to Seattle from Cleveland."
Cons: "Seats did not incline and no options for entertainment on board. For a 5 hour flight it would be more enjoyable to have these."
Pros: "The pilot talked us through the turbulence and gave adequate and great information. The crew was polite and nice."
Cons: "Overall the food options didn't include an actual meal. That wasn't the specific flight's fault- more of an overall problem."
Pros: "Boarding moved along smoothly, seats were decent enough"
Cons: "I did not have a food/drink menu in my seat compartment, nor did anyone else in my row. When the stewardess walked by, I asked her for one. She rudely snapped at me "well you should have one" and then she walked away. She never came back with a menu. I was so stunned by her sharp attitude that even the girl sitting at the row across from me felt bad and asked for a menu from someone in her row just to give it to me. At that point I didn't even want to look at the menu and I didn't order anything. I probably would have otherwise. I don't know why this particular stewardess acted like that towards me as I had not interacted with her previously nor was I rude at all. All I said was "can I please see a menu? I don't have one." This was my first time flying with Frontier and I will probably not fly with them again. I will stick with United and Delta. I have never been treated like that on an airline before."
