Scores according to KAYAK customer reviews
Cons: "Auxiliary generator broken so plan got hot very quickly. Flight was 2.5 hrs delayed due to another mechanical failure. And then once we were in air they generously notified us that the WiFi was broken. Utter garbage."
Cons: "We were sitting in the plane on the tarmac for 3 hours waiting to take off. The crew did a very poor job announcing what was going on."
Pros: "Crew was friendly, attentive, and informed us of any delays going on. Great experience!"
Pros: "Good customer service and comfortable plane"
Cons: "Sat for an hour before take off."
Pros: "Seats had slightly more leg room"
Cons: "Seriously a coffee pot running hot water kept us on the ground another 45 minutes to an hour, very frustrating. There was one flight attendant Jordan that just made me uncomfortable she seemed rude and short even with her co workers. The food looked like it wasn't worth it on flight. Over all this experience made me second guess booking through Alaska and I'm going with the rei credit card instead too."
Pros: "Nice and friendy crew, and it seems I can always hear the pilots on Alaska. On other airlines, they are hard to hear. Alaska pilots were pleasant to listen to, as well. Comfortable seats and good leg room at back of plane."
Cons: "My seat was full of crumbs when I boarded, hair was sticking out of the magazine in front of me. I wish there was some cleaning/disinfecting of the plane prior to a new flight boarding. It's flu season and that's exactly what I got 2 days after flying home. I gave the food and entertainment 1 star as I didn't use either. Should be a NA option."
Pros: "First time flying Alaskan. Out of all the US-based airlines I flew with, Alaskan was the cleanest, friendliest, and quickest."
Pros: "Free movies!"
Pros: "We arrived half an hour early! Bags on time."
Pros: "Snacks are good and crew is very friendly. Kept us up to date with arrival times. Would fly again with Alaska"
Cons: "With delta, the movies are free. Didn't like that I had to pay for certain entertainment on Gogo"
Pros: "Very accommodating staff"
Pros: "The staff was extremely pleasant. Plenty of leg room. Departed on time and arrived ahead of schedule."
Cons: "We were asked to exit the plane at Tarmac and I was traveling with 2 little children. There were a lot of stairs to get off the plane and then walk back to terminal and then a lot of stairs were there to get back to terminal. I was hurting in my knee and my kids ears were hurting badly because the pressure was not controlled while landing. It was a very bad experience and I will definitely think twice about flying Alaska again."
Pros: "Captain's flight commentary good Crew fine. Plane fine."
Cons: "slow, untimely, disorganized boarding Couldn't get seat assignment online or at airport."
Pros: "Was seated by a very nice couple."
Cons: "The plane was crowded. I was very upset to find that on a 6 hour flight I not only had to pay for entertainment I didn't even get to finish watching what I paid for. Was really pissed that on a 6 hour flight I had to starve because you also charge for food! Didn't have a credit card only cash that was refused so I was unable to eat."
Pros: "Boarding was fast"
Cons: "Space between the rows is narrow, I understand it has nothing to do with the flight itself."
Pros: "The flight crew supplied plenty of drinks throughout the flight."
Cons: "Those seats are just never comfortable in economy class. They need lumbar adjustment."
Pros: "Flight service kept things light and friendly, efficient. Although the takeoff was late, attempts were made to shorten the flight so that overall delay was minimized on the back end. Thank you!"
Cons: "Can't think of anything."
Pros: "New equipment"
Cons: "Sparse food."
Pros: "Flight was 30min faster than we expect, awesome :) we arrived 30min earlier :) she was the most beautiful pilot i ever saw. ."
Cons: "Everything was just fine. ."
Pros: "Seats were not bad - headrests actually fit my head right!"
Pros: "Great service and extremely friendly staff. Brand new plane. More economy legroom then other carriers"
Pros: "I love the leg room on Alasks flights, and I'm always impressed by the professionalism and respect Alaska employees show to their customers."
Pros: "I am a tall woman and rarely ride in an airplane without my kneecaps brushing the seat in front of me in coach. Not sure what Alaska Airlines is doing differently, but I had knee-room to spare on my flight to Seattle!"
Cons: "Upon our arrival in Seattle, it seemed that the gate wasn't quite ready for us and we spent a restless few minutes "getting docked" for departure."
Pros: "I liked the seats and comfort, nice crew an allt that."
Cons: "That we were late. I wasn't their fault cause it was because of the weather, but it made me stressed and I couldn't relax."
Cons: "This flight was first delayed, then not listed on the reader board. Then the flight added a stop over in Seattle for the the only reason that the crew was maximizing their allowed time to work. This delayed arrival at final destination. They could have brought on a fresh crew in Chicago but they did not do that."
Cons: "A child crying the whole trip behind my seat. No effort by mother to stop child from crying"
Pros: "Arrived on time even tho it took off late."
Cons: "I don't believe I was offered the chance to reserve a better seat when I made my reservation."
Pros: "The fact I was going home."
Cons: "I've never been treated the way I was treated on an Alaska Airlines flight. I flew Delta there and Alaska Airlines home. The flight crew made rude comments about some of the other passengers. I'd I can hear them so can the other passengers. I will say my flight from Seattle to Anchorage was better. The Chicago to Seattle had me on the verge of tears. I think Delta may be choice to travel from now on. . I don't like paying all that $$ to be treated like I'm an irritation or nuisance on Mother's Day no less."
Pros: "We arrived alive"
Cons: "Very small, cramped plane and they managed to completely lose one of the items I checked that I have still yet to receive. Wouldn't have been so bad if they didn't only have 1 attendant working the baggage claim desk at RIC, causing me to stand in line for 30 minutes for them to essentially yell me that they had no clue where my bag was. If I had realized the second leg of the trip was overseen by American Airlines and not an Alaska affiliate, I would have likely chosen another flight."
Cons: "Should not have to pay for movies other air lines they are free"
Pros: "Got there earlier than expected. Staff didn't charge me for one drink"
Pros: "After we got off the airplane, the flight attendants went out of their way to help a woman who had trouble understanding English find and get to the baggage claim. The service and kindness exemplified by the staff really made the whole experience wonderful."
Pros: "One of the flight crew sang us an original song just before landing. It included directions on safety etc. and it was delightful, funny and sweet. Then when I was in the terminal two of the same crew helped me figure out how to get to baggage claim."
Cons: "No complaints."
Pros: "Friendly, caring, and knowledgable staff"
Cons: "No hot food choice on 6+ hour flight."
Pros: "Boeing plane was so comfortable and modern and new."
Pros: "More legroom than expected."
Cons: "Movies were not free."
Cons: "I got a "faux" window seat and felt very claustrophobic and misled."
Pros: "The crew and passengers were friendly. The most fun I've had in a plane in a long time!"
Cons: "Nothing! It was great!"
Pros: "On time & easy"
Cons: "Nothing I remember"
Cons: "I had tried multiple times to get a seat at the ticket counter and at the departure gate...when I was finally able to get a seat there were no aisle seats available...that was not helpful as I am required to get up every 1.5 hours and walk around the cabin because of health issues Beverage service was once and no snacks..I am used to this so brought along some snacks but it would have been nice to have peanuts and not only a cold drink but then some coffee."
Pros: "Best price"
Cons: "On display travel info"
Pros: "The turkey sandwich I had was made with actual sliced turkey, not deli meat. This was a treat for airplane food, and it wasn't very overpriced. It was also a very spacious, comfortable flight. The crew were very friendly and helpful. Alaska is definitely one of my preferred airlines."
Cons: "The flight was a little longer than it normally is, but I think there were some strong winds which slowed it down."
Pros: "Friendly, professional, easy going & helpful staff. Comfortable seats, with plenty of leg room (I'm slim and 5"6"). I like that carry-on bags can easily be checked at the gate (when flights are full), and that there is no penalty for doing so."
Cons: "Boxed meal (Mediterranean Tapas) was missing an item that was listed on the menu."
Pros: "I was given a surprise upgrade after a very long week. It was amazing! The flight crew was fun and they took excellent care of me. Thank you so much."
Pros: "Polite staff, awesome service."
Cons: "We would enjoy free wifi even if we can't have free movie streaming."
Cons: "I cancelled my flight, and although I purchased flight insurance, still ended up having to do a bunch of paperwork and losing money. After experiencing cancellations on other flights, this was by far the worst. The $150 cancellation charge on Alaska is unbelivable and the insurance KAYAK provided through Allianz was awful."
Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"
Cons: "Not really an experienced flyer. Overall the flight seemed good. No issues with airline or airport. Just don’t understand self-important people that feel compelled to push the overhead storage limits with their bags."
Cons: "1.5 hour delay...no reason given!"
Cons: "Flight was delayed and completely packed so our family could not get seats together"
Cons: "More leg room and seat width. I don’t like having other passengers pressed against me."
Pros: "Love the fact that the head rests move to support your head better."
Pros: "The seat was great, I wish all seats on the plane were that comfortable"
Cons: "Nothing, everyone was great"
Pros: "The male crew member was excellent. He was responsive and speedy with trying to find a solution. He gave me a few flyer miles for my trouble and was empathetic, which is rare."
Cons: "The tv/monitor didn’t work so there wasn’t any entertainment for the majority of the flight."
Cons: "No meal option and my video screen volume did not work"
Pros: "The crew was great and super nice!"
Cons: "Screens with games, more leg room, and not having kids behind us messing with tray tables the whole flight."
Pros: "Boarding was easy."
Cons: "I am 6' 1" tall and weigh 220, so not out of the ordinary and I felt like I was stuffed into a sardine can."
Pros: "Not comfortable a little but scary on the flight to Detroit. Way better coming back to Denver"
Pros: "great crew!"
Cons: "luggage. what a nightmare. I waited 30min for my luggage (after a delayed flight) only to be told by a fellow PASSENGER that some of our luggage was directed to a FRONTIER CAROUSEL. I then had to wait by that carousel till I found it. so much for "bags in 20min guaranteed""
Pros: "Inflight experience was fine. TVs didn’t work but Flight attendants are friendly on Delta, cramped seating - but not unlike other airlines."
Cons: "Regular fare seat assignment not available prior to gate . Airport concourse F - poor - limited services. Customer Service seemed uninterested and unable to provide service both on phone and at gate. I’m a frequent United flyer & today’s Delta service experience made me more loyal to UA."
Pros: "Early and middle seat was open!"
Cons: "Coffee tasted like fish. :("
Cons: "At least one hour late"
Pros: "The crew on the airplane was great. We had 2.5 hours turbulences but the crew started to give out drinks as soon they got the ok from the pilot"
Cons: "We went in LGA to the Baggage drop off and the employee there was super rude. On the flight to New York with Delta we had to check our carry ons at the gate because it wasn't enough room for bags in the airplane.so we asked when we checked our one suitcase if we can/should check our carry ons to avoid having to do it at the gate. The delta employee told me sure no problem. He checks in my one suitcase I purchased gives me the tracking paper and says ok have a good flight. I asked him so what is with our carry ons and he told us that that would cost 25$ and we can't check those in at the drop off?!?We ended up taking the carry ons with to the gate and then off course there wasn't enough room on the airplane that we had to check it in. And surprise it was free?? We had never issues with Lufthansa, icelandair etc. with checking our bags at drop off to not needing to carry it around and than still end up to check it at the airplane. Every airline has been more than happy that we volunteer to check our bags that they don't have the trouble at the gate."
Pros: "We boarded close to on time, no hassles. Allowed my husband and me (retired military) to board early, thank you."
Cons: "LAX security is awful. We never left the airport (arrived LAX from Sydney AU) yet were forced thru security again. Had to remove shoes, was scanned and "frisked" by TSA to get to Denver. To go to Australia, Denver TSA waived the removal of shoes, skipped the scan for the metal detector and no one touched me, ditto for LAX on the trip to Sydney. Where's the uniformity or standards for TSA?? Why did I have to be subjected to this garbage on the way home?? This is why I despise flying. It makes no sense to me. This ruined what was a great vacation."
Pros: "Free drinks and snacks - great entertainment system (please read this Frontier)!"
Cons: "Boarding process was agonizingly slow and ineffective"
Pros: "JFK to Denver the flight Attendants were once again great. Lots of entertainment choices again. The usual rough air coming into DIA."
Cons: "From JFK to Denver the seats were to close for leg room by an inch or two. The temperature was hot most of the flight."
Pros: "Love the built in tv’s with free entertainment."
Cons: "The plane got delayed on the runway and the shut the engines off so the plane got super hot, but even after we got up in the air it never cooled down. Normally I’m freezing on flights, but I just sat sweating this whole flight. It was terrible."
Pros: "The crew at the airport was very courteous and helpful."
Cons: "No food; not even offered water; I asked a Delta employee about our seats and she was very unprofessional (mind you I'm traveling with kids and my boarding pass said that seats were to be assigned at the gate)."
Pros: "The seats had plenty of leg room and the crew was was very kind."
Cons: "My seat was uncomfortable and I was seated in the only row of the aircraft without entertainment for a four hour flight. Then on top of that the passenger next to me removed his shoes and you could smell his feet from a mile away but the flight attendants never requested for him to replace his shoes."
Pros: "I can’t make it in mexico city on tuesday, wednesday’s performance had to be cancelled and we need to pay the cancellation fee 11500 mexican pesos, please reimburse on the credit card"
Cons: "I can’t make it in mexico city on tuesday, wednesday’s performance had to be cancelled and we need to pay the cancellation fee 11500 mexican pesos of the studio and musicians"
Pros: "I usually have had great experiences with Delta. The meal selection was limited. By the time they made it up to my seat they had run out of what we wanted. Also, the entertainment system at my seat and my husbands wasn’t working well. One of the bathrooms had a cabinets Tvst oliiiooooiiooooioiooiiiooiio"
Pros: "In a pinch they were able t"
Pros: "Love the inflight entertainment and the usb plug for phones. Flight left on time and go in a little early"
Cons: "Did not love getting charged $2 for headphones and the girl sitting next to me getting them for free. Super annoying"
Pros: "When deplaning in Denver, I was impressed that the captain was the staff who got behind my wheelchair and offered to push me up the walkway :)... New aircraft, kind staff, shorty flight!"
Cons: "Nothing disappointed, butt i didn't have any good besides pretzels."
Pros: "Not much to like here. The new crew was pleasant"
Cons: "Old crew was surly. Plane had much problems and finally replaced. Left 5 hrs late. Delta claims it doesn't have to compensate for a late flight - just a cancelled one so guess which this was The baggage fees are obscene and the gouging of the customer is immoral. No wonder people hate the airlines."
Cons: "Excellent service excellent pilot"
Pros: "Overall, the flight was very smooth and I thought the crew did a great job."
Cons: "I know this is a federal regulation, but I have to mention it as it is part of the boarding process. For the life of me, I can't understand why it is necessary to go through security again after re-entering the country. Understandable that I have to go through customs, but going through security again is ridiculous."
Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"
Pros: "Free in flight entertainment"
Cons: "One of my bags went to Santa Fe"
Cons: "This is my third flight this year with Delta and every time we wait for the "crew" to get off from another flight. And as soon as they get there we can board. It's getting very annoying. Fix it."
Pros: "I love the new snack choices! Way to go Delta for offering Kind bars now!! This is awesome."
Cons: "Tiny old plane, props blocked my window view, no entertainment system."
Pros: "The staff of the flight were very friendly and attentive. They were great!"
Cons: "I'm tired of Delta making it IMPOSSIBLE to experience benefits of my loyalty. I flew literally AROUND the world in the past 6 months and it STILL doesn't qualify me for anything more than Silver elite? Seriously? When you use a voucher because of their error to lower your ticket price, but still pay cash for it, why does that then automatically exclude you from upgrades? Poor customer loyalty, in fact, non-existent these days."
Pros: "Early arrival. And service"
Cons: "I was assigned very last seat and there is no reclining option."
Cons: "long wait and delayed flight"
Pros: "WiFi, good flight attendants"
Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"
Pros: "One male attendant from the first class cabin - super sweet and attentive to our needs even tho we're not seating in the premium cabin"
Cons: "Junior attendants in economy comfort seat - so lazy and whiny!"
Pros: "Left reasonably on time, arrived a bit early, able to find overhead storage for my roll-on, even boarding in Zone 3"
Cons: "Very tightly packed; minimal comfort for the flight."
Pros: "From the Ground crew to the Flight crew, you can feel the genuine care and thoughtfulness of everyone! They even remember you, if you fly often enough, and let you know how much they appreciate your business."
Pros: "Very professional and caring."
Pros: "plane had individual movies for free with each seat!"
Cons: "Flight was repeatedly delayed. Ended up being over 3 hours late to depart due to weather. Another delay due to mechanical problems."
Cons: "I've only experienced delayed flights with Delta ... and this was no exception. It wasn't weather-related, nor a late flight delivering a plane - just no ground crew to service the plane between flights."
Pros: "nice snack"
Cons: "We did not board at the scheduled time, although I believe we arrived on time. The crew was demeaning and singled out individuals who were causing the aircraft to not move. It was in a very pretentious manner, not like southwest personnel who have similar antics but with a playful tone. The plane is a small one where bags don't fit overhead and many head bumps occur. We arrived fine which mean the flight was successful but it was not very enjoyable."
Pros: "The crew was nice"
Cons: "I didn't like the fact that I didn't get my luggage with me when I arrived to casablanca as I lived 4 hours away from the casablanca. I have to come back the next day to get my luggage. I was very mad about it.plus I noticed one of my luggage has been damaged so now I have to buy another one because I can t use it. It was disgusting."
Pros: "Everything was great"
Pros: "Crew was tight, friendly, flight comfortable & painless."
Cons: "The plane had a mechanical issue that they needed to address (due to the fact that they prior crew did not address it) and we sat in the gate for 2 hours waiting. No worries water was offered by crew and the flight had no food."
Pros: "On time flight. We were even a little early."
Cons: "Those seats are just crammed in there aren’t they?"
Pros: "Pretty standard flight"
Cons: "Inconvenient timing and overcrowded with obnoxious children sitting on laps. No attempts made to change their behavior by crew or parents."
Pros: "Fine for a domestic flight. Normally, American Airlines offer a small snack to go with the drinks. But on this particular flight, they went the United way and offered nothing but drinks. Crew was pleasant enough during the flight, although they didn't greet half of the passengers entering or exiting the plane."
Cons: "Flight was a little late taking off and therefore getting to Denver. But there was no announcement about it. There was one announcement from the captain, but it was so soft that I couldn't hear anything. Upon landing and arriving at the gate, we stood there for a while with no lights on and seatbelt sign on, but no explanation of what was going on. There was no welcome to Denver message either. Maybe their announcement system was down."
Pros: "Not using kayak."
Cons: "Worst flights in history. It took three days to get from Italy to the US. Do not use kayak!"
Pros: "Great service in first class"
Cons: "3rd flight in two weeks suck sitting next to a morbidly obese person. They should be forced to purchase two seats."
Pros: "The crew was amazing - agreeing to work extra because it was Christmas eve and they wanted us all to get to our destinations for Christmas. They were very gracious and helpful."
Cons: "We were over an hour late to leave. I understand the reason for the delay because of weather. What I was disappointed in is that the delay was not announced until our actual scheduled time to leave. It meant people coming to pick me up didn't get the change information in a timely manner."
Pros: "Flight crew had a great sense of humor - they were extra friendly while boarding as well, made traveling with AA the best! Boarding was delayed due to previous flight but our pilot even managed to get us to Denver early! Wish I could have this crew everywhere I go!"
Pros: "it was fine. flight left on time and the crew was nice."
Cons: "that you have to pay $100+ for economy plus to get the legroom you used to get for a regular ticket."
Pros: "Friendly crew. Due to the apparent regularity of excessively delayed American Airlines flights, they had the staff at O'hare bring a cart filled with cheap canned juice and Diet Soda to lessen the blow of their consistently delayed flights."
Cons: "Like every other American Airlines flight I've ever been on, it was delayed. Including the American flight from Denver to Chicago. We pay entirely too much money to these airlines for them to deliver such painfully mediocre service and consistently delayed flights. I recommend that this airline do a SERIOUS audit of their Preventative Maintenance/Service division across their hubs. If I fly American, I would bet my entire checking account that the plane will be delayed well over 2 hours."
Cons: "Missed that flight because my finair was delayed at Helsinki"
Pros: "Missed the flight. Money was not refunded."
Pros: "More improved than the last trip I took with AA to Denver. Efficient boarding."
Pros: "Flight was on time through United since we had to be rescheduled from our original flight with American."
Pros: "Nothing. AA is the worst airline. Period."
Cons: "Rude flight attendants, delayed flight (as always), just AWFUL."
Cons: "Could not read paper when passenger in front reclined seat. No space between rows."
Cons: "My flight was actually processed under American Airlines. Oddly, the confirmation email stated it was Finnair."
Pros: "Flight not entirely sold out. So they let my 14 month grandson have an empty seat between my daughter and I. That was a great gift since he doesn't sleep and is jumping and crawling all over the place. And I'm sure the other passengers were breathing sighs of relief!! Also super smooth landing and nice flight attendants."
Cons: "Flying with an active 14 month old toddler boy and of his "stuff" is nothing less than anxiety provoking. Not much the airline can do.."
Pros: "On time"
Cons: "Cramped seats. Entertainment system outdated"
Cons: "Plane was too old, flight attendants were rude"
Pros: "The departure time. This left enough time to get to the airport and go through security without rushing!"
Cons: "Sitting in the middle Paying for luggage ( I wish Southwest flew out of ORD)"
Cons: "Due to two flight delays, I traveled an additional 24 hours, on top of my 20 hour original flight. Albuquerque Airline staff were rude, dismissive, incompetent, and each individual I spoke with gave me wildly differing information. The two delays (leading to approximately 48 hours of travel) would have been stressful enough, but the callous, ignorant and unprofessional attitudes of American Airlines staff (and staff in general at Chicago O'Hare Airport) really disappointed me. This was even more striking compared with the professional service I received from British Airways (from whom I purchased the tickets). I was ashamed that my country could lag so far behind in terms of basic customer service and problem solving."
Cons: "Requested for wheelchair assistance but none provided?!!"
Pros: "Timing and transit time was excellent"
Cons: "Food was horribe and no dedicated tv per seat"
Pros: "I liked sitting next to my friends."
Cons: "Lack of leg room"
Pros: "They showed American ninja warrior."
Cons: "Everything. The flight was delayed greatly even though the plane got to Chicago only slightly late. Then they make us board and just sit in the plane for an hour. Then finally we start moving, the plane is uncomfortably hot even with the air blowing on me, the flight attendants look like they hate their life, it was honestly horrible and I will never fly with American Airlines EVER again."
Cons: "We were delayed for 6 hours due to a maintenance issue. Horrible customer service"
Cons: "Always a problem with these guys"
Pros: "Couldn't of been more impressed especially after being hung out by Southwest!!!"
Cons: "We have flown to Europe recently on SAS and that airline was so much more comfortable than airberlin. Things we missed: personal TVs on the seats, good leg room (airberlin was quite cramped), and small attentions like a disposable towelette. I got no sleep on airberlin."
Pros: "Staff was very friendly and helpful"
Cons: "Experienced 4 hour delay with mechanical and weather problems. But glad they put safety first"
Pros: "They put safety first"
Cons: "Frustrating 4 hour delay"
Cons: "I am very disappointed in my flight. I am 6'7 and paid for an exit row seat. When I got to the airport they gave me a different seat with no leg room. They told me they changed planes and there was nothing they could do to help me. I tried again at the gate and again nothing. Will never fly again."
Pros: "Room on flight in coach was sufficient and im 6 ft 2"
Pros: "The entertainment was pretty good . There was a good variety of movies and music"
Cons: "the cabin was extremely small, absolutely no leg dpace unless you were in first class, specially if you are a taller person."
Pros: "Overall pleasant experience."
Cons: "I was not aware that the FinnAir flight was being handled by American. I missed it when reading my itinerary and had a brief panic when I showed up to the international terminal and my flight was not even listed on the board. Perhaps it could be written a little larger? Thanks."
Pros: "Good value"
Cons: "Poor food quality"
Cons: "That small space!! This is a long flight and you have no room to move around at all!!!!!"
Pros: "Appreciated that the cre didn't wake me to give me my landing card. They did make sure I got one though."
Cons: "I didn't get vegetarian food that I ordered over the phone and I did made sure that it said vegetarian Jain meal on the ticket that I printed. Very disappointed because no point ordering then. I paid $1234 for the trip. And I am traveling because of funeral."
Cons: "Seats too tight. No room"
Pros: "Food, entertainment and free checked bag. Can ask for more!"
Pros: "In flight service."
Cons: "The first check in kiosk associate was turning us away because we reached 30 minutes prior to scheduled departure. However, by then they knew that they were going to be at least 1 hour 30 minute late. Then when kayak emailed us about the delay, the check in people let us in. Ultimately the flight was three hours late."
Pros: "Food, blanket & pillow,"
Cons: "Most of the video screens did not work. Long flight with no entertainment!"

Cons: "Very cramped plane. Very hot in the cabin. And veneration wasn't good, cabin smelled like farts. The bathroom door lock was broken and didn't close all the way either. Had to gate check my bag again."
Cons: "While going inside the flight they told me there is no room for Carryon and gave me ticket to book the luggage. When I went inside the Flight there is lot of room to carryon's, why they have to lie this BS."
Cons: "The crew no food no pillow no blanket"
Pros: "We'll coordinated."
Pros: "I liked the Lufthansa flights using Airbus Aircraft the entertainment system is the best."
Cons: "The entertainment system on the boeing planes is not necessarily the best, the screens are smaller, the selection of movies is not upto date and even Live TV does not work"
Cons: "See above comments."
Pros: "In flight entertainment was great!"
Pros: "The comfy seats"
Cons: "The fact that I had to pay to watch tv. Maybe people should have to pay for movies, but not for watching tv. Flights and till we takeoff can take a while. It would be nice to have some free entertainment. The plane was very hot when we were boarding."
Cons: "The seats are tiny. If you drio something, you can't reach down to pick it up. The food was burnt. The app isn't downloadable in China. The overall experience makes me not want to ever fly United again."
Cons: "Entertainment and food could have been better."
Pros: "Excellent as expected."
Pros: "Good entertainment for a long flight."
Cons: "A power jack could come handing."
Pros: "Flew on Delta Airlines"

Pros: "The flight was a head of schedule and very smooth."
Cons: "It was freezing cold. I was wearing a sweater and was freezing."
Pros: "I have metal leg braces. The staff was helpful getting me from terminal to terminal. They were very helpful."
Cons: "Having a leg brace makes difficult I am blessed I can move a little without them. I had to move a short distance without my brace. No place to put it back on."
Cons: "i missed my flight because my flight left Toronto late"
Pros: "Pilot was very happy and friendly! Very informative throughout flight."
Cons: "On the return home, I was seated in the last row right next to the lavatory. I was bumped into at least 40 times by other passengers and flight attendants."
Pros: "not a damn thing"
Cons: "Weather delays are a typical part of travel. What's not typical are 5+ hour delays and sitting on the tarmac and watching your connection take off without you. First Class seats morphed into Economy center seats the next day, with nary a hotel room in sight. Thanks for nothing."
Cons: "The flight was very hot and uncomfortable!"
Cons: "This flight never happened it continued to get canceled and canceled!!"
Pros: "The flight attendant finally took care of it after I complained a couple of times."
Cons: "That you changed our seats, and, that there was no room in any of the overhead bins. So, the flight attendant told me that I needed to fight my way through the people coming toward me back up the aisle and check every overhead bin all the way back up to see if there was room for my one suitcase. Others had brought more than one bag up there. Finally they checked my one carry on bag. The ride was also really bumpy, worst that we've ever experienced. But that was due to weather conditions."
Cons: "Everything! Even worse than my previous flight. Delays were inexcusable, staff ridiculously unfriendly and just bad attitudes all round. Very unpleasant experience, won't be using this airline ever again."
Pros: "Nice clean plane, very friendly and helpful crew."
Cons: "The hour delay."
Pros: "The crew was fantastic despite the entertainment system wasn't working"
Cons: "The entertainment and wifi was nonfunctional for the 8 hr flight."
Pros: "Pre-check with United"
Cons: "Did not get connecting flights boarding pass from the beginning. Short connection time - was very stressful"
Cons: "Couldn't reserve/request a seat. Assigned to me About 1.5 hours prior to boarding. Had to wait Around the gate. Should have told me I would not have any choice. Could have walked around. Got a middle seat. It was a long flight."
Pros: "The flight attendant was great! Pleasant, polite and professional!"
Cons: "The flight from ORD to ABE was on a plane with expired maintenance logs or inspections? We were delayed 2 hours in arriving for what seemed like a pilots lax in paperwork. But what does a customer expect from an airline who knows they that customer by the balls?"
Pros: "Great boarding at ORD."
Cons: "My seat"
Pros: "Movie selection and delivery/access was very good"
Cons: "Seat legroom is insufficient. There was a water leak in the ceiling that dripped cold Wster on me for a portion of the trip."
Cons: "The flight was late by 5 hrs due to mechanical problems. The gate crew was confused about what to do and we ended up with several deboardings and boardings. Food was terrible. The entertainment system did not work."
Pros: "Everything else was fine"
Cons: "For such a long flight and quite expensive some food should be provided. I have never flown before like that (over hundreds of overseas flights) and had NO FOOD given at all."
Pros: "the flight attendant crew was super nice throughout the entire flight."
Cons: "the tvs weren't working for the all the seats, and the food was not very tasty."
Pros: "Flight itself was good. Nice flight attendants. Funny pilot."
Cons: "The lady at desk to board the flight made me check my carry on. I had assumed it was because the plane was full, but when I got on the plane there were more than adequate spots to stow more bags. There was a compartment across from my seat that remained open the entire flight. While I completely understand the need to check extra luggage when the plane is full, I was very upset when I saw it was not. I intentionally fly with a carry on for the convenience, and to be inconvenienced for absolutely no reason made me not want to fly with this company again for fear it could happen again in the future."
Pros: "The flight crew was very helpful and organised the connection between two flights very well under pressing circumstances when there was only 15 min between the flights and the boarding gates being in opposite ends of a big Munic airport"
Cons: "The flight was delayed for 2 h, so we had to run through Munic airport for connected flight. Good sport, but rather tiresome."
Cons: "8 channels of looped shows and movies. Too long a flight for that...and then have to use my device to watch on the free part of the wifi.so no battery left. For this price? And I booked through Lufthansa but flew United. Bad form."
Cons: "The plane was tiny and the seats were tiny. Could not carry on a bag and it took a long time to get the bag back from having been gate checked."
Pros: "the japanese speaking flight attendant was exellent! she was very observant to passengers needs. i was also pleasantly surprised by the entertainment system."
Cons: "there was a flight delay due to maintenance, which was inconvenient."
Pros: "The trip had minimal turbulence. The landing was smooth."
Cons: "-The 767 was old. -It did not have any power ports for my laptop or cell phone. -The interior was old and dated, reminiscent of the 1980's. -The TV screen for entertainment seemed to be smaller than a Samsung Note 5. -The seats are unreasonably narrow and not comfortable. -I had an isle seat and my shoulder width is literally wider than the seats. -Every time the isle cart went by, it hit my left shoulder. -The seats in general seating are too small and were cramped. -God forbid if we had to egress out of the plane. -There were no adjustable head rests, like other airlines have. -The Flight Attendant for my section DID NOT make me feel like I was a valued customer, even though I paid over $1500 for flight. -She scolded me for asking "Why," when she TOLD me that I needed to sit in one seat, even though the seat next to me was vacant. She literally treated me like a child. - NOT COOL. Overall, in comparison to my last international flight, I WOULD NOT recommend United. I feel like I paid too much for my experience with United. Aer Lingus has better/newer aircraft, better cabin crew, better entertainment selections to include music and a selection of movies to watch at your convenience, more comfortable seats, provide a better environment, and a better value for your experience. Aer Lingus was also cheaper. So if you are reading this, please shop around if you are considering United to fly."
Pros: "Flight left on time crew friendly and attentive"
Cons: "Long flight could not get a diabetic meal !"
Cons: "It was delayed so I had to take another flight. I've been trying to get this flight refunded"
Pros: "What I liked? That the flight ended and I could get off the plane."
Cons: "They charged to pick seats. They charged to carry on a bag. They charged for any drinks. The seats had NO padding. The seats didn't recline. The gate at O'Hare was dark and dirty. The travelers in my flight would have scared the residents of Mos Eisley."
Pros: "Fast boarding and that's the only good quality. No refreshments or snacks offered without a price tag included. Seats don't recline. Uncomfortable hard seats without any head rests for Support. Small tray tables that won't hold a laptop or drink."
Cons: "It's been 45+ minutes after landing that we have been stuck on the runway unable to dock the plane due to some delays. How Terrible is it that the pilot gets on the radio to say he has no updates or much information to give! People are antsy, children crying and this delays all passengers with other accommodations. Seems like there's no communication or organization from Frontier at all!!'"
Pros: "Getting off the plane"
Cons: "Being in the plane"
Pros: "It was cheap. The boarding was smooth. It wasn't overbooked. There was space for my carryon. Crew was nice. Was on time."
Cons: "No free beverage. Small seats and no leg room. Not happy about the carryon charge but whatever."
Cons: "I had broke my phone coming from a music festival so i had no way to call them, traffic and construction made me miss my flight by 20 minutes and they would not help me get another flight or refund my money"
Pros: "Nothing was positive while using Frontier Airlines"
Cons: "Everything was pretty unpleasant: 1.) hidden baggage fees ($45 round trip would be one thing for a CHECKED BAG, but $90 collectively for the round trip is FRAUDULENT) Especially when most airlines don't charge for carry on bags or it's at least calculated in the final cost. At first when I booked this trip with FRONTIER $180 for my tickets looked like a decent deal, UNTIL I WAS TOLD AT THE COUNTER THAT I HAVE TO PAY $45 each way for a FRIGGIN CARRY ON BAG!! turning my reasonable and anticipated $180 trip turned into almost a $300 (NEARLY doubled my cost!) had I known I could have at least packed more into a checked bag for that price. 2.) my flight was delayed 4 hours on my outgoing flight, cutting into my personal time off and no compensation or even a kind gesture like a free McDonald's sandwich when you land...you guys really have poor quality and seem like you don't really care about the paying customer 3.) staff seemed clueless and didn't know how to answer customers questions as to why our flight was delayed!! 4.) mechanical issues with plane were the cause, or at least that's what the copilot or captain Just HAD TO MENTION TO US RIGHT BEFORE TAKEOFF, causing everyone to stir and raise eyebrows. 5.) to top off him mentioning the mechanical issues they were having with the plane the flight was rough..I've never been more tense or anxious on any of the other 30+ flights I've taken in my life. Pilot didn't seem to know how to handle turbulence."
Pros: "price, updates and friendliness"
Pros: "Crew was very pleasant. We were able to board easily. Like the newer seats that don't take up so much space so there is more leg room."
Cons: "Cabin was freezing, until one of the crew came back and adjusted it."
Cons: "Seats are hard and our row was not allowed to recline. Late take off and late landing, plus we did not have a gate for 20+ minutes after landing. Crew acted like they wanted to be somewhere else."
Pros: "Easy flight"
Cons: "When I booked no option to pay for luggage. Had carry ons. Very expensive. Felt that was a bit of bait and switch. Lots of extra charge for carry on. I would have packed lighter and brought less had it been clear. Cost me an extra $75 each way"
Pros: "Best Frontier experience I've had in a long time. Everything was very good and despite a delay getting the plane to the gate in Chicago, we were able to make up almost all of the time!"
Pros: "attendants were friendly, patient and in good humour."
Cons: "cramped, no room. high priced snacks and bevs,"
Pros: "The price and schedule choice"
Cons: "They try to trick you into buying other things and speak in a condescending way on the website. There's no entertainment not even a magazine. The seats which are super ridiculously tight don't recline and there's no cushion for your head. You have to pay $3 for a soda and the batteries are so small you can barely fit which is great when there's pee all over the floor. The outbound flight was delayed over an hour with no explanation and perfect weather. When I asked for more water in the tiny cup, she poured it half way. I guess they are really trying to save money. Makes me wonder they took shortcuts on safety to save a few dimes."
Pros: "a smooth ride. we left a half an hour late."
Cons: "paying the carry on fee"
Pros: "Overall quickness and friendliness of staff."
Cons: "No free food."
Pros: "O'hare airport."
Cons: "I was unable to print a boarding pass at one of the many kiosks - it informed me I needed to speak with a Frontier agent. The line for the agents was about 2 hours long, too long to wait to make the flight. After being told by a frontier employee that I'd just want to get in to the line to rebook on a later flight (9 hours later) I proceeded to speak with a momentarily vacant agent who, helpfully, printed and handed me my boarding pass. I arrived at the gate to a closed door and ended up needing to rebook anyway. I decided to just not go on the trip.... wasn't worth having to deal with Frontier 2 times in one day."
Pros: "I like averything about timing and been punctual."
Cons: "You have to pay for everything! The seats are uncomfortable. They should have at least free WiFi, so you feel the pain of the seats!"
Cons: "Short-staffed, so short tempered workers.kiosks did not work. Nickled and dimed on everything. Like flying in prison. No light and a cold hard bench seat. Awful."
Pros: "I really liked the brand new and updated Airplane. The fit and finish was quite nice and the electronics and lighting were nice."
Cons: "The crew was poorly trained in virtually all aspects of their duties. They had no coordination among themselves and ran around like a bunch of chickens with their heads cut off. One attendant yelled at a passenger at one point. They kept turning the lights on and off abruptly and made a HUGE deal about throwing away the trash because otherwise they will get stuck doing it all. The intercom system was also abused as the attendants made, at times foolish announcements, with a different attendant speaking almost each time. One would almost yell while another would speak very softly. The intercom system and speakers on this plane, particularly from the cockpit, when the captain spoke, sounded like it was from the Vietnam War era. For a brand new airplane, this was a disappointing shortcoming in the technology. We experienced excessive turbulance for the majority of the flight as well. I do not know if this is something the pilot is able to overcome but on this flight, it certainly was an issue as i almost had to vomit from all the very abrupt and excessive motion. I would not rate this as one of the better flights i have been on."
Pros: "Seats were more comfortable than I expected"
Cons: "Flight was delayed more than 2 hours."
Cons: "Seats are aweful. Charged bags, especially carry on are deceptive. Flight late"
Pros: "They are charge me for carry bag $40"
Cons: "They are charge me for carry bag $40 I book and pay online ticket $60 only Thank tto"
Pros: "That I got home."
Cons: "The horrible seats, no space, everything has a cost from soft drinks to carry-on. The one inexpensive flight ended up costing another $86 and that wasn't any food or drinks. Additionally when you check in they lead you to believe you HAVE to buy a $9 seat because nothing else is available when on reality, if you don't pay the seat costs 0 at the gate. Never again Frontier!"
Pros: "The crew"
Cons: "My flight was over three hours late. There was no compensation for anything, as well as no explanation as to the delay."
Cons: "delayed two hours and were not kept updated, checked suitcase was torn when we picked up at baggage"
Cons: "Worst customer service"
Pros: "This flight was ok but my history with frontier airlines is awful. I only flew them because it was the only option."
Cons: "Lack of customer focus or care. Hidden fees for everything."
Cons: "the fact that i was delayed more than 5 hours on the departure and more than 1 hour on the way back. Why is there an option for entertainment when none is provided? Also you need to pay for the food"
Pros: "I liked the price of my ticket. Not having complimentary food and drink was OK to maintain the low ticket price."
Cons: "Seats are not conftable"
Pros: "Crew service"
Cons: "Free drinks and Snacks weren't provided"
Pros: "On time, friendly and affordable prices"
Cons: "Not very clean, the airplane was messy"
Pros: "The price of the ticket"
Cons: "The seats were awful, no padding what so ever!!!!"
Cons: "3 HR unknown delay"
Pros: "The flights were great. Left on time and arrived early!"
Pros: "Good flight"
Cons: "Just remember, you get what you pay for. My flight was $148 from Denver to Chicago on Frontier."
Pros: "Flight attendants were nice no different than any other time I have flown on a plane"
Cons: "There were 2 small girls 3 seats in front of me and they screamed at the top of there lungs for most of the flight. Neither one of their parents seemed to be really bothered by it and so I think the flight attendants should have put an end to the screaming since the parents wouldn't. Also the kid that was sitting in the seat in front of me threw up and it dripped though his seat and onto my bag"
Cons: "Bad experience overall"
Cons: "The boarding and exiting process was unapologetically slow. The cabin was super hot the entire trip and didnt feel there was enough circulation. There seats are horrible. The staff only came by once and completely skipped me and when i flagged here down, she was very annoyed."
Pros: "Initial cost of flight. Later disappointed that it was as expensive to check three bags."
Cons: "Seats were uncomfortable, mere plastic shells compared to other airlines and seats in our area did not recline. Very little legroom as rows seemed to be compressed. Being told we had to pay for checked or carry on luggage on-line so we checked three bags since we had to check one anyway. Then noting other passengers getting on the flight with bags they were putting in upper compartment without seeing how it had been verified that they had paid to bring on luggage to put in the overhead. I feel like a schmuck for paying for bags when it did not appear anyone was checking to see who paid and who didn't. Not even soft drinks were free."
Pros: "The flight was great and everything leading up to the luggage pick up was good. The flight landed a half hour early and the flight left on time. Getting the luggage took an hour and a half and they sent us back and forth between two different pickup locations. What should take 15 minutes took much longer than desired."
Pros: "2 of 2 trips, over an hour late due to time sitting on the tarmac."
Pros: "Easy check in, we took one check in bag instead of three carry-ons and paid online to keep the price under control."
Cons: "Had to sit to wait fr long time to get to arrival gate after landing"
Pros: "Same as many other reviews, upset I had to pay extra just to select not a premium seat, but literally a seat on a flight I already paid for & pay to either check a bag or carry a bag on. I'll never fly frontier again & probably never book through kayak again either."
Cons: "Frontier airlines. Rigid and unable to admit that they made a mistake. Caution towards anyone who flies with their special low discount rates. Many opportunities were taken by company to recover discounted fare (and I am not referring to any baggage costs) Besides money, they ruined a special weekend through delays. Think twice! In fact, my comment is in reference to customer service in general. Everything is a fight now. I'm not a screamer, I'm rational. I laid out,clearly, where their policy was contradicted and that some empathy was in order and in the process was hung up on once and have not received a reply to my last email. If you gave no intention to achieve quality customer service, why pay for the department? Maybe they don't."
Cons: "Lost my luggage and people at check in were rude"
Pros: "Funny crew. Did not crash."
Cons: "Cramped, all the charges and steps involved checking in the day before."
Pros: "seat dont recline"
Cons: "pay for every thing even a drink seats dont recline"
Pros: "The crew were friendly and helpful"
Cons: "(a) No wifi (b) Being nickled and dimed for too many things (c) really uncomfortable plane. Even the $30 premium seats are terrible and don't recline If I had known about carry on and seat assignment fees I would have just flown on a different airline because there would have been no difference in price."
