Excellent

Very good service, all were ok/excellent

Recommend Qatar Airways to everyone! Service, leg room, and food are all great.

Cons: "The crew at check in was really inconsiderate and has given us false information! Despite of what documents were required and submitted I was not allowed to board the plane."
Pros: "The check-in crew in Chicago was very nice and efficient. The flight crew on-board were not friendly, they were very curt and rushed, and did not go out of their way to be helpful."
Cons: "Friendlier staff during the flight. Better food for breakfast. The connection port for my headphones did not work...I would not have been able to watch movies if I hadn't brought my own single connection head phones."
Pros: "The crew was really nice and very attentive."
Pros: "Food is delicious"

Pros: "This was my first experience with Qatar & it was outstanding. Crew members are extremely courteous & helpful. The aircraft seats in economy class were roomy & comfortable. Bathrooms were kept clean throughout the long flight. Food was very good as was the selection of flight entertainment. Can't thi"

Cons: "flight attendant should be nicer"
Pros: "The crew was very friendly and helpful throughout the flight"
Cons: "The boarding process in Chicago wasn’t great. Zones were not used"
Pros: "Delighteful experience"
Cons: "Better guidance at transit stop"
Pros: "Plenty of room to move around"
Pros: "Food was excellent and the crew updated us through out the flight"
Cons: "That fee for overweight was excessive"
Pros: "Q-suits. Very comfortable and private. Great upgrade to the 777. WiFi now available for very reasonable price"
Cons: "Bus transfer to Termial 5 is VERY poorly organized and takes over an hour. This makes it harder to get to Terminal 5 even if you don't have to clear security again. Seats had a bar under the padding at about the position of my hips. Uncomfortable to sleep for several hours"
Cons: "Ord to Doh: People kept window blinds open all through 15 hour flight Flight temperature kept very warm"
Pros: "Good food and good hospitality"
Cons: "The gentleman next to me had broad shoulders, so I spent most of the flight with my body a bit twisted, and eating without being able to move my right arm normally was undesirable. The cabin was kept a bit warm throughout the flight. We had a long wait (30 - 45 minutes after leaving the gate) before takeoff."
Pros: "Food was great Seats were comfortable Everyone was super nice"
Pros: "Courteous and friendly staff, on the plane and at the airports. Gave advice and directions when asked. Asked about time for food serving and said anytime you want something, come to the galley."
Cons: "A chorus of crying infants..."
Pros: "Great service and crew"
Cons: "I’m a 6’3” in shape man. I selected the bulkhead seats for extra leg room. Great crew, but my shoulders stuck past the seat edge 3” on both sides. Qatar should revise their claim of most room in cabin - this 12 hour flight was one of the roughest I’ve had in a long time comfort wise."
Pros: "Good food. Great staff and service"
Cons: "I wish there was more seating room and unusually long waiting time for toilets."
Pros: "Checkin crew was rude and was not at all respectful"
Cons: "Checkin crew was rude and was not at all respectful"
Cons: "Boarding at JFK very disorganized. Poor system. No vetting of wheel chair users many fakers."
Pros: "Every thing is great."
Cons: "Food Seat great service"
Cons: "Delayed"
Pros: "On demand entertainment systems seem standard, as I’ve flown Qatar several times and always had it. Friendly staff. And Doha is a great connection airport."
Pros: "My flight from Chicago to Doha was late to come in and there was a gate agent waiting for us and two other passengers with a sign when we got off the plane. He told us that our flight had already left but he would get us on the next one. We ended up getting seats on the next flight but then were also given the option to get a temporary visa and explore Doha for the night. We opted for the comped night which included a very nice hotel and $100 in meal vouchers. We absolutely LOVED Doha and the hotel and food was fantastic! I don't think I have ever received better service from an airline or a hotel. We ended up walking around Souq Waquif and the downtown until 1am (we are two young females!) with no issue and just used Uber to get to and from the hotel. Everything was so well laid out for us! No complaints whatsoever!"
Pros: "smooth and on time with efficient service."
Pros: "Hospitality, boarding process"
Cons: "Food was slightly undercooked (chicken). Should have better process to check for that"
Pros: "Enjoyed the food and the service from the crew. Plane was new and relatively new and comfortable."
Cons: "The check in agents were not very polite or helpful. They did not offer much assistance and help for a first time customer on Qatar Airways. My bags were also not loaded onto the plane and had to arrive on a later flight"
Pros: "Seats are comfortable with plenty of leg space. Aircrafts were clean and tidy. Landing and take off were smoothest I have ever experienced."
Cons: "Menu choice was very basic and quantity was also poor. Food quality was below par in terms of taste and presentation. In-flight crew was inefficient and flow. Meal trays laid on meal tables for hours after the passengers finished food. Flight attendants literally responded in over 30 min of call. I pressed special meals online before boarding. However, the flight attendants were not sure. They went back to kitchen to verify that and return with the ordered meal."
Cons: "Luggage items are missing."
Pros: "It was excellent."
Cons: "It was excellent."
Cons: "No consistency with hand luggage. My companions and I were held to strict weight limits. Others were getting on with three and four bags."
Pros: "The entertainment options were fantastic! The flight attendants were very cordial and hardworking."
Cons: "I was very pleased with my flight. I really have I complaints."
Pros: "everything was as expected from a world-class in the travel world."
Cons: "In economy class, the seats are not as roomy as I thought and leg room space is not suited for overseas 12+ hours travel comfort."
Pros: "Vegetarian food options"
Pros: "The Chicago flight was more than hour late so had to miss my cincinnati connection. Had to wait for 4 hours at the airport to catch my next flight- making the long journey even longer. No priority lounge access provided to make up for the delay. Qatar never getting my business again."
Cons: "Boarding staff give us wrong advice to make extra money from the passenger. They also pressurized us to decide quickly. our each check in baggage was over weight 1 KG or less than 1 KG due to faulty scale at home. Instead of giving us a choice or advice that you are allowed two more hand bags. They pressurized us to make one baggage over weight from all 7 bags and harassed us to do it quickly because they are closing counter in 20 minutes. That's how they charged me another $65. Also they lied on the counter that your seats are in a row but when i went into the plane our seats were separate. Lesson learned don't trust the person over the counter of Qatar airways."
Pros: "Everything"
Cons: "The boarding was unusually long. We stood in line for twenty minutes to board the plane. This was difficult for many. The staff and airlines were unorganized and scattered."
Pros: "A380 FLIGHT! Woo Hoo!"
Cons: "We arrived around 39 minutes early and the whole process was very smooth"
Cons: "The carrots were hard and the bread was cold."
Cons: "No AC for an hour before takeoff - very uncomfortable. Audio for tv did not work."
Cons: "Flight was delayed a bit due to a couple passenger booking/misc issues. 1st class didn’t get gate bevfood service. Oven was busted so my meal wasn’t available. Entertainment console had all channels functional except — not really an issue I just really wanted to have ESPN playing in the background"

Pros: "Jeff was our flight attendant in first class. He is an excellent flight attendant. He has an amazing attitude and his manner made us feel as if we had been friends with him for years."
Cons: "Passengers who pay retail for first class on domestic flights should get access to the Delta lounges even without the AE card. Other airlines do this, and we have come to expect it."
Pros: "The boarding was fast and very well handled."
Cons: "My flight from Chicago was two hours late and that's why I missed the flight from Atlanta to Buenos Aires. No one helped and did not know that the flight was delayed and I had to find a place to sleep. I'm not satisfied with the experience and I have not yet arrived in Argentina because of the whole"

Cons: "Chinese Eastern did not try to help and solve my problem."

Cons: "Layover"
Pros: "Short flight"
Cons: "Too cold Not friendly boarding agent"
Pros: "N/A"
Cons: "2.5 hour delay for no apparent reason at first (supposed mechanical issues with plane) and then waited on plane at gate for a missing pilot who never got picked up from his airport and got stuck in Chicago traffic trying to get to O'Hare. Eventually had to take pilot from another flight before leaving at 8:45 when flight was scheduled for 6:00am."
Cons: "Had a death in the family and no one would help me get back home"
Pros: "Seats were comfortable. Snacks!!! Nice flight crew."
Cons: "I liked everything."
Pros: "The Gogo Inflight wifi and entertainment did not work for even a minute. I choose flights based on their amenities and this one had offered full WIFI service which swayed me to choose to fly with Delta. I'm not sure who is to blame about this issue but I'm pretty frustrated that it was completely dysfunctional."
Pros: "No fee to get on an earlier flught"
Cons: "When I tried to rebook online this flight was not an option"

Pros: "Excellent flight. Nice new aircraft."
Pros: "Delta's free in-flight wi-fi for entertainment (movies, tv, music) on your own device is a big plus. Not so easy to find (there's sparse information in their magazine or seat-back brochure), but once you find it there's a wealth of options."
Pros: "Crew service was excellent"
Cons: "Poor leg space"

Let us sit in empty bilk head seats

Pros: "Gate attendant was a superstar."
Cons: "6 hour delay due to part that St. Louis sent for - twice. Will never fly through ST Louis again on AA. Terrible Domino's pizza and water were complimentary after 4 hours delay. Returned to gate twice. 11 a.m. flight arrived at 9:30 PM ( 3 hr flight). Poor gate attendant was left to fend for herself as she was fed false and contradictory information."
Cons: "Late and then mechanical issues."
Pros: "Crew was great"
Cons: "Seat was uncomfortable. Flight was much too crowded"
Pros: "Crew was friendly and nice."
Pros: "Once we took off the flight was quick and smooth"
Cons: "Our flight was delayed from 11:55 am take off to a 1:30 pm take off."

Cons: "Stop delaying & canceling flights, especially last minute"
Pros: "Crew"
Cons: "The delays due to software"
Pros: "Really easy boarding and flight. Great in flight entertainment options."
Pros: "All was good"
Cons: "Nothing to complain about."
Cons: "Person in front of me had seat reclined from take off to landing. Nobody checked. Nobody told him it had to be upright during takeoff and landing. I believe that is a safety issue. Isn’t that why the flight attendants are there?"
Pros: "Seat assignment process was great and considerate of my preferences."
Cons: "If AA could fix its luggage handling process that would be great. BOTH (!) of my bags have been lost on this flight. Both have been eventually located, recovered and delivered to me, but experience was not pleasant this time."
Pros: "Flight attendants were friendly and thoughtful."
Cons: "Seating is too tight. Hard to believe that in 2019, major airlines still have seats without any electrical or UBS outlets for charging devices."
Pros: "Crew friendly and accommodating, even on short flight"
Cons: "Good - no complaints."
Pros: "Comfortable seats and snack / drinks service"
Cons: "Delayed flight departure and bumpy landing"
Cons: "I was apparently "flagged" by British Airways for extra security checks. As I understood it in London, I was randomly selected for this security check. This then apparently meant that I was to be flagged for all subsequent flights. This meant that in Chicago, after going through two other security checks that day (Zurich and London) and completing customs, I had to engage in a full Homeland security check. This involved removing protective covers from my laptop and phone that were hard to get off (not meant to be taken off regularly) and a full body search that I did not have to do in London. After many hours of traveling, this was very a frustrating experience."
Cons: "I will never, ever book with Kayak again"
Pros: "Flight crew was great. The plane was half full, so the attendants allowed us to move."
Cons: "Terrible landing in Charlotte. The plane was rattling and had an annoying whistle."
Cons: "It was not clear that I needed a different 6 letter code to checkin using the AA website. I finally got frustrated and called AA only to find out the code was different. The codes should have been the same or you should have referenced it on the website when I tried to check in"
Pros: "Our plane was late getting to the gate. They kept us informed and turned it around pretty quickly. There were storms between Chicago and Rochester so we were rerouted. As a result the hour flight was an hour and a half. The pilot kept us informed and it was a very smooth flight. So even though I was over an hour late arriving I so appreciated the communications and the safer route. AA seems to be communicating more than other airlines and I appreciate that. Flying is absolutely no fun anymore so you take what you can get for the positives."
Cons: "WiFi wasn’t working so I couldn’t communicate my late arrival to family picking me up."
Cons: "On my first flight from SLC to ORD I asked 3 different American Airlines employees if I needed to pay for my carryon before I got on the plane. They all said no. I got on the plane, put my carryon under the seat in front of me and everything was great. I landed in Chicago, got to my gate, went to board and this very rude employee stopped me after I scanned my ticket and told me I couldn’t board with my bag. The EXACT bag I had boarded with in SLC. After harshly grabbing my bag and putting it in the carryon basket to check for size, she wouldn’t let me pass by her into the boarding bridge and told me I was going to have to pay. I tried explaining that I had asked I’m SLC if I needed to check it and they had all said no and that it fit under my seat. She said, “I don’t care what they said in SL, this is what I’m saying here.” And directed me to the front desk where I had to pay $50!! $50 for a carryon backpack that fit under my seat comfortably 20 minutes before!! Without saying a word (cause I didn’t want to yell at the poor girl behind the desk) I paid the $50 and proceeded to enter the bridge but before I passed through, the rude woman said, “have a nice flight ma’am” and scoffed!! An audible scoff. So I’m short, I hate American Airlines and I will do my BEST to not have to fly with them in the future."
Cons: "Flight was delayed by untold circumstances causing us to miss our connecting flight to Venice."
Cons: "I’m not sure how this flight was as I missed it due to a delay from YYZ to ORD"

Pros: "On time departure and early arrival"
Cons: "Nothing"
Pros: "Nice crew Spacious plane"

Cons: "Flight was delayed almost two hours due to crew staffing issues."
Cons: "My check in bag it’s lost got wrong boarding pass even when I told them I had electronic boarding pass on my phone. Really disappointed with this."
Cons: "Great trip"
Pros: "Not turbulence"
Pros: "Was on time."
Cons: "Not eventful."
Cons: "Luggage did not make the transfer on time (Chicago-Charlotte after Tokyo), although they had about 45 minutes to load it. Do not buy an international ticket with less than 1.5 hours transfer time. (It took 45 minutes to get through customs/immigration and retrieve luggage for transfer."
Cons: "There was just an announcement that the refreshments will be served shortly but there were no refreshments. Take off and landing was horrible. Flight was shaking way more than usual."
Cons: "All was excellent! Only the internet was not working good , payed for all flight access but most of the time the internet was not working. Anyway I contacted support team and they refunded me"
Pros: "on time"
Cons: "very cold"
Cons: "This made the check in process extremely frustrating and confusing. Traveling with my elderly dad who had to squeeze between two large men for 7 hours because people who actually booked the airline got priority seating. We had to pay an extra $500 to upgrade to comfortable seats. Not pleased w Kayak."
Cons: "Forced to check my carry on. Took 30min for the bags to come out on the carousel. Which is why i never check my bag."
Pros: "I enjoyed the entertainment because I don't watch movies in the theater often. The movies I saw in-flight were recent films I've been wanting to see and made time pass fairly quickly."
Cons: "I'm not a giant, but there definitely was not enough leg room in the main cabin. I could not sit comfortably, especially in the middle seat."
Pros: "Speedy boarding"

Pros: "Good flight. Arrived on time"
Cons: "Jet bridge was broken and needed repair. Delayed departure."
Pros: "very friendly staff"

Pros: "The crew were exceptionally friendly and helpful. They made the negatives about the flight much more bearably be their excellence service whether during boarding, in flight, or after landing."
Cons: "I booked the flight originally through british airways and expected your standard, modern plane for cross atlantic travel. Boarding to find myself on a 767 designed (and likely built) in the 80s was rather disappointing."
Pros: "Plane was ancient"
Pros: "The ginger ale."
Cons: "This was my return trip with more delays due to maintenance issues of the aircraft. 10/17/16 flight 1585 was the outgoing flight delayed five hours on my departing trip. I waited at the baggage carousel 15 minutes for my bag after over an hour delay due to switching aircrafts. With a flight arriving this late in the evening with the low volume of bags checked (due to checked luggage charges), this should not be the case. Five minutes to gulp down ginger ale."
Pros: "All flights were on time Greatly enjoyed the trip"
Pros: "Flight was on time. Plane was clean. Staff very professional."
Pros: "It took off on time and life was good."
Pros: "They were friendly. Seats are rarely comfortable..."
Cons: "I think all planes need better leg room...."

Pros: "The flight was on time and smooth."
Cons: "Too many people with carry on luggage."

Pros: "Flight attendants were absolutely amazing!!!!! They made the trip very enjoyable!"
Cons: "Food!"
Pros: "Crew was nice; not out of their way, though."
Cons: "Food, movies, space"
Pros: "Great crew"
Cons: "Very uncomfortable seats"
Pros: "Crew was nice."
Cons: "The entertainment system for an international flight was lacking compared to other airlines."
Pros: "Corralled group lines allowed people to get in line when I was ready versus open entrance for each group"
Cons: "Plane arrived late to gate making my flight arrive in Austin an hour later. I have an ride home, too."
Cons: "Delayed Swiss flight 8 tue 12 dec 2017 led to catastrophe"
Pros: "Quick"
Pros: "Comfortable Flight"
Cons: "Inflight WI-FI doesn’t work, it kept on dropping in the middle of the movie or it went back to the beginning. Couldn’t see a movie."
Pros: "Nothing! I will make sure to never use United for any flight from now on."
Cons: "Everything! The customer service was terrible and cold. Non refundable tickets should state in huge red writing that they are non refundable!!!"
Cons: "You better get rid of basic economy."
Pros: "No delay, friendly crew"
Pros: "Boarding was fine, no delays. Crew was nice, no complaints there! I had an empty seat next to me, so could stretch out. Luckily I brought a blanket with me, since I know from previous experience it's always too cold on planes."
Cons: "The entertainment didn't work on my iPad or my iPhone. I kept getting an error. Also, the WIFI is way too expensive."
Cons: "United has new seats that have absolutely no leg room and are very uncomfortable. I will make sure never to fly United again. This was 3 hours of agony."
Pros: "Associates were nice and knowledgeable. The airplanes were comfortable. Love the onetime performance of scheduling."
Cons: "Unite Airline performance wasn't the good. Also, there was nobody in Chicago to help us with the transferring process."
Pros: "I had the exit window and that made a huge difference in my trip as I am a 6ft tall woman who is all legs."
Cons: "It was slightly turbulent and TSA at O'hare airport are the rudest and laziest humans on the planet."
Pros: "Snacks and drink"
Cons: "Average"
Pros: "Flight was on time."
Cons: "Seats are uncomfortable and cramped."
Cons: "The pilot's landing was way too fast. I was sure that the plane would come to a stop in Hwy 280 at the end of the Asheville runway. That plane probably needed a major brake job after that landing. We ended up at the absolute very end of the runway!"
Pros: "Wasn't thrown off"
Cons: "Another delayed flight with United"
Cons: "They might as well have thrown us in a car trunk the crew was very unaccommodating they didn't really care about us and the room legroom is ridiculously smal. On the connecting flight, the last flight the plane was two thirds empty and the crew made us sit in our assigned seats, crammed together telling us that if we want to sit in a seat with more legroom we have to pay $180"
Cons: "Too many seats too close together. The entire trip was too hot and stuffy. The flight attendants showed minimal care about the uncomfortable hot and stuffy environment."
Cons: "The United mobile app as well as my emails stated that the gate was B3. Upon arriving at gate B3 and attempting to board, I was alerted that I was at the incorrect gate. The gate was switched to C11. However, my app did not alert me nore did it reflect the gate change. I didn't receive a text or email update. I had to run to the different concourse nearly missing the fling."
Pros: "Crew was lovely."
Cons: "Seats BARELY reclined, and leg room was minimal. The whole flight was very uncomfortable even for someone who's only 5'3" who flys regularly. Also, no in flight entertainment for a long flight. Total fail."
Cons: "Turbulence was insane"
Pros: "We'll coordinated."
Cons: "The seats were terribly uncomfortable (including her flight to Chicago). The cushion made me slide down the seat and could not get comfortable."
Pros: "My flight in was smooth, seamless and amazing. The crew was so lovely."
Cons: "My flight out was a shot show that included a four hour delay and frantic running to gate changes. The staff was very unhelpful. The snack was awful."
Cons: "I went on this trip as an veterinary humanitarian out reach. I was also guardian to one high school student so that she might have an experience of such to guild her future. Her flight was missed booked to leave after mine, I attempted to rebook my flight with Luthansia but they would not let me me even partial rebook. I attempted a number of times to rebook the flight but their solution was extreme financial gain for them when more reasonable alternative could have been arranged. They canceled my entire return flight and left me stranded. I had to piece together a return flight on a shoe string budget. Thankfully American Airlines was understanding for it appears Luthansia and United are not."
Pros: "In flight entertainment worked. Staff was friendly."
Cons: "I had no issue with the delay, things happen. I was dealing with a knee injury and the gate plan had us all over the airport. It was quite frustrating to get to a gate in another terminal only to get told we were being moved back to the terminal we had just come from! Then that gate was changed again, involving another long walk on said bad knee!"
Pros: "The promptness on the flight -the friendly crew - arriving on time means the most, also the flight itself was smooth"
Cons: "There were no ticketing agents at the gate adding an hour to the flight."
Cons: "2.5 hour delay. No working bathrooms. Couldn't hear the tv and headphones that they gave out were useless."
Pros: "The crew was awesome and the flight wasn't bad at all"
Cons: "It was suggested that I didn't bring my carry on with me so I left it to be voluntarily checked and it came back ripped"
Cons: "flight was delayed for over 5 hours and gate was changed over 6 times"
Pros: "Over all it was a great flight aside from the rain delay but that's Mother Nature for you"
Cons: "Flight was delayed due to severl technical issues. Crew at least offer free drinks or snacks for the five hour delay."
Pros: "Nice clean planes and seat, on time performance"
Cons: "The flight attendant was hard to understand"
Pros: "Nothing"
Cons: "I was angry that I had to fly to Houston before heading to Phoenix which made my arrival in AZ much later than I had planned. My flight had been rescheduled since I missed my flight the night before because the first flight had been delayed. So the new flight was a longer trip because of the extra layover. The overall flight was a mess."
Pros: "Nothing"
Cons: "Multiple delays and gate changes; chaotic boarding; shabby plane condition (bathroom looked held together with duct tape)."
Pros: "That the plane actually took off and landed fine."
Cons: "Flight delayed almost 2 hours. I booked this flight on this airline as my previous flight on a different airline was delayed over 7 hours."
Pros: "Nice crew and boarding staff. The plane was repaired rather than the flight being cancelled."
Cons: "No airconditioning on the ground so the extra time on the tarmac was very uncomfortable. While taxiing, a screen went blank, so the plane returned to the terminal, deplaned, and there was a two hour delay for the repair."
Pros: "Tons of food and water. Movies good. Staff on plane were excellent. Clean bathrooms and peacful. Nice that headphones were provided."
Cons: "Seats should not be set to go back so far, if a person in front sets back all way, no space passenger behind. The seats should be calibrated to go back less of an angle."
Cons: "Some inspector idiot decided that the exterior cover stickers weren't "up to code" literally half an hour before my flight, delaying us 2 hours. I got onto a different flight at the last second, then the same thing happened to that plane. Brilliant on their parts. I almost lost a job interview thanks to your people."
Cons: "Boarding went quickly but then waited almost 35 minutes on the plane to take off. Once the plane landed there was again a wait to pull into the gate. Spent more time waiting on the plane than the flight itself."
Cons: "This flight was also delayed. It was bade enough the first flight was delayed almost an hour, but this flight also left late from the gate."
Cons: "You need bigger tray tables!"
Pros: "Arrived early. Flight attendants were pleasant."
Cons: "Wanting to charge $40 for bag!"
Pros: "Arrived 30 min early"
Cons: "The flight was super delayed because Frontier was sharing a gate with another airline..."
Pros: "Crew was good. They were late boarding the plane, but the captain made up the time in the air."
Cons: "There's extra charges for carry ons and beverages Majority of the seats have no leg room No in-flight entertainment or wifi"
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: "Easy"
Cons: "Shared my row with 500lb people and though two rows ahead of me had two empty seats I couldn't move to be comfortable. This beast of a woman couldn't put her arm rest down and therefore her body was smashing mine the whole time. It was disgusting."
Pros: "The crew had a great attitude and was able to make us laugh despite the fact that we were leaving late."
Cons: "The plane was dirty- there was balled up gum wrappers, food wrappers, and bites of food on the airplane floor. To make maters worse the carpet was already stained in multiple spots. My tray table also was dirty with sticky soda that had spilled on a prior flight. I was quite disgusted by the condition of the plane."
Cons: "On flight from Tampa to Chicago nobody charged me for carry on,and on a way back they charged me 60 dollars,so,this is the last time to travel with Frontier"
Pros: "They only had one plane, it was weather delayed at its previous airport, then it ariver with mechanical problems. Customer service promised me the flight would be leaving that day, it ended up being cancelled. We were at the airport for 9 hours before they cancelled which meant that rebook in a flight on a different airline cost twice as much and was difficult and could only be done for the next day. Customer service was useless. The gate crews are third party contractors and can't do anything because of frontier's policies. I reported them to Dept of transportation and they keep sending the response that they have too many complaints to respond to and they wI'll get to it eventually."
Cons: "Terrible service from Denver. Missed flight due to Frontier check in desks being overwhelmed. Was there two hours early, told to go to outside curbside check in. Terrible delays when returning to Denver on the plane. Was held on the aircraft for 40 minutes before they could get us off. Bad experience. Won't be flying frontier again."
Pros: "Crew was very friendly ! The ticket agent working the checkin before security was very unfriendly didn't really even speak, everyone else made up for tha"
Pros: "The price of the flight"
Cons: "The fact that frontier will not transfer checked bags to a different airline. If at all possible, I will never fly this airline again"
Pros: "Flight crew was very nice and courteous. The flight itself was smooth."
Cons: "Seats do not recline and not enough leg room. When boarding they should let people in the rear of the plane board first."
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: "Nothing"
Cons: "By far the worst flying experience I've ever had in my 60 years of flying constant crew understating the severity of the problems and delays. Flight was over 8 hours delayed and we reboarded at least twice."
Pros: "Little."
Cons: "Worst flight of my entire life."
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."
Pros: "Smooth flight and excellent recovery from a strong gust of wind seconds before touchdown."
Cons: "Had to pay for snacks. No entertainment that I was aware of."
Cons: "The flight had a 7 hour delay before it was officially cancelled. Throughout the entire ordeal no one from the Frontier staff could give us a straight answer on when and if we would be taking off. Most horrible service and flying experience EVER!"
Pros: "Did have good leg room in exit row."
Cons: "Thought we got such a good deal on flight, but had to pay extra for carry-on and even to choose a seat. The seats did not recline, but maybe that was because we were in exit row. Boarded an hour late to clean up from last fight because of (per their announcement) vomit."
Pros: "The seats were mildly comfortable enough and the price was exactly what we were looking for."
Cons: "The boarding process seemed unorganized and hectic. People not in the proper zone were able to board. Some of the crew did not take their profession seriously and I seemed to have annoyed them by asking for some sort of service. I did not like how they try to shove the frontier airlines credit card down your throat. The food was boring, expensive, and, oh yeah, I had to buy it. There was absolutely no entertainment which made flying the worst."
Pros: "Nothing!!!! Never will fly with Frontier again!"
Cons: "Poor communication poor customer service extreme long what on land both deporting and landing. Wth No apologies!"
Pros: "No delays, soft landing, flight attendants were very courteous, landed early each flight. I heard all these horror stories & I actually had a good experience."
Cons: "Seats were not that comfortable."
Pros: "It was a direct flight"
Cons: "That they charge for luggage and while boarding it looked to me as if anyone could have brought a carry on and they wouldn't even noticed or checked to see if it was paid for... so why bother charging!!"
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: "The seats are amazingly uncomfortable. Your ticket price is good , until you realize you pay extra for absolutely everything."
Pros: "The flight itself was decent if you don't mind non reclining seats and no beverage service."
Cons: "The 3 hour delay on top of the fuel spill outside the plane that added another hour of sitting inside the plane. Flashing lights and everything with no updates whatsoever. Horrible. Never again."
Pros: "wait times kept changing and got totally ridiculous. my uber cost me twice as much and i was delayed 4 hours. never flying with you ever again."
Pros: "Cheap"
Cons: "Arriving at O'Hare to take this Frontier Flight.. there was a line a mile long for Frontier Airlines. They created a mess and did not try to assist those of us in line. The line was to check in bags. There were 3 different flights, and it was so unorganized. I realized after an hour that I didn't need to be in this line. I had paid for a carry on, thank goodness otherwise I would have missed this flight, like many did behind me. The flight attendants were rude! I needed to purchase a drink to take some medication, and they made me wait. It was ridiculous."
Pros: "Not much, the time it takes to get to the places is short which is nice."
Cons: "Delayed flight, only $15 dollars of food too late and not acceptable at restaurants, too long of a delayed flight."
Pros: "Nothing"
Cons: "Website didn't work for hours when I wanted to check in. When I arrived the plane was delayed three hours before they said that the back rows 30-38 all had to rebook because they had an issue with the plane. That next flight required me two take 2 connecting flights (7 hours of flight time) and arrive 19 hours after my scheduled departure."
Pros: "Boarding was pretty easy and the crew was nice."
Cons: "The seats weren't comfortable at all and did not lean back unless you were in the first three rows. Not a lot of leg room made it hard to get some much-needed rest. Took forever to get off the plane when we landed."
Pros: "Your flight's delay was unchanged; I likes its consistency."
Cons: "I did not like paying $5 more for my checked bag. Although I did log in to see if I could check in more than 24 hours before the flight nothing suggested that I should pay for my bag though I could not do seat assignment at that time. I did not like that I paid $5 for set assignments inferior to what my friends got by taking their chances. Although I understand your motives, not showing what the free alternative is seems a bit smarmy. The one hour delay on the tarmac before we could get to a departure gate was not directly your fault, but it was annoying."
Pros: "We got there safe and sound."
Cons: "The gates were changed almost at the last minute and we didn't hear any announcements. A few passengers we're almost late for boarding. I found out because some lady came by and asked if this was the flight to some where else. That's how I found out the gates were changed. I told the rep to make sure that they make the announcement so everyone knows of the changes. I could of got on the wrong plane and missed my flight."
Cons: "I did not like the carry on fee, nor did I like the fact that beverages in flight cost additional money. This seems like a really cheap flight option but all of the other fees add up."
Cons: "Flight home was 30 minutes late and not one rep apologized or updated passengers. Horrible communication."
Cons: "The website was poor it was difficult to access in order to check in the seat were fixed and uncomfortable the advertise low fares appear to be more deceptive when you start adding in additional fees for baggage and seat assignments"
Pros: "A very smooth landing."
Cons: "I waited in line to check in for 45 minutes or so. No-one was at the desk. A customer ended up finding a security guard and asking them to find a Frontier employee. They paged for one over the loud speaker. How embarrassing. A woman started checking customers in, with the attitude of the century. She was angry, rude, and just plain nasty. This should not be the face of Frontier. When friends and family ask, "How was your flight?" All I can picture is that woman and her pinched tight frown of a mouth, angry grimace of a face and condescending hateful tone. Good day."
Cons: "Flight was delayed 1.5 hours. Waited in line at bag check for 2 hours with little communication as to why it was such a mess. Employees from other airlines had to help with the chaos."
Pros: "The flight departed early and arrived 30 mins earlier! Nice!"
Cons: "Flight attendant stated the water was free but then when asked for more said you needed to buy it for $1.99/bottle! Ridiculous!"
Pros: "Comfortable flight."
Cons: "Very delayed and kept us waiting longer than they promised and we're very clear as to why."
Cons: "4 HOUR delay at gate. Felt sorry for gate attendant who came out ever 15-20 mins., telling us the work was done but paperwork was the reason for the holdup. This went on for the entire 4 hours."
Pros: "Loved the flight attendant. She went out of her way to make everyone relaxed and feel at ease. She even sang to us, it put a big smile on my face especially after the terrible experience I had with the ticket agent."
Cons: "Your staff did not give me the right info about baggage check. I checked one bag in and paid for it, that was cool. But when I got to board the plane they told me I had to pay an extra $40.00 for the carry on. Should the ticket agent not of given me this info when I checked and paid for my other baggage? Because of this experience, I will never fly with you again! Teach your staff to give people the correct info, instead of pulling a fast one on them to make more money."
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."
Cons: "The staff was informative and had great energy, unfortunately though, I had a very hard time getting comfortable. I'm 5'5" and I had absolutely no leg room, I felt claustrophobic and uncomfortable the entire flight."
Pros: "everything going well from start to finish."
Cons: "I was a little concerned when the person in the window seat next to me left soon after take-off. I figured he was headed to the washroom, but never came back. These days, you never know if it might have been something that should have been mentioned."
Pros: "Even though there was a ton of cancellations and delays from the day before due to Chicago weather, we had no problems with leaving on time and even arrived at our destination early. Flight crew was pleasant. Too bad TSA security took forever. They must have been short of help. Only one person checking tickets & ID's and only 1 lane for the scanners. Wtf? Good thing we got to airport early or we'd miss our flight."
Pros: "NOT MUCH!"
Cons: "This was my first time using Frontier Airlines. The price and schedule met my needs. After paying $30/each way for checking my bag plus paying for a seat (would they allow me to stand?) not sure it was so good a price. The worst was when three flights came in at the same time and ALL the luggage was sent to the same area. I WAITED AN HOUR TO GET MY SUITCASE."
