Pros: "Yes"

Pros: "First class was A+"
Cons: "Not a thing"
Cons: "Nothing. I've flown on worse."
Pros: "Average"
Cons: "Seat back screens. More space."
Pros: "The crew did very well. The seats could have been a little more comfortable, the lumbar could have been a bit more stiff for lower back support, the arm rest up and down function did not work, and a little more space between rows and seats would have made it more comfortable."
Cons: "The seats could have been a little more comfortable, the lumbar could have been a bit more stiff for lower back support, the arm rest up and down function did not work, and a little more space between rows and seats would have made it more comfortable. The bathroom was too narrow."
Cons: "I really wish you guys told me that in permium seating that the snacks you guys offer had nuts. You guys up sold me by telling me how much I'm going to enjoy the free drinks and snacks on the phone. So I said screw these people seemed nice and not pushy. Very upset that this wasn't giving to me."
Pros: "Great! Decent."
Cons: "5 gate changes."
Cons: "Delayed. Flue season folks. If your sick just don’t travel!"
Pros: "Leg room seems a bit more spacious than other flights. Very comfortable. Nice experience."
Pros: "All good"
Pros: "Awesome"
Cons: "N/A"
Pros: "The staff and crew were fabulous! The choice for viewing movies and/or TV shows was wonderful! I'm looking forward to flying with them again very soon!"
Cons: "NA"
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."
Pros: "Promptness."
Cons: "Only beverages. Perhaps a little something, like nuts"
Pros: "Crew top notch, they were professional. Always courteous and friendly. Luggage arrived on time from cruise ship."
Cons: "Nothing bad to say."
Pros: "First time on Alaska. Great experience."
Pros: "Nice movies Comfortable seats"
Cons: "Noisy air con Seat not reclining Headphone jack not working No storage space"
Cons: "Nothing"
Cons: "Gate misinformation snafu."
Pros: "crew's upbeat attitude"
Cons: "very limited drink choices"
Pros: "Accommodated my disabled mother through the whole flying process. Thank you"
Pros: "This was a completely booked flight during Xmas week, and the flight was delayed an hour. Alaska Air did a great job of accommodating these difficulties. When I checked in online they had a notice asking if we would volunteer to check bags for free because they knew overhead space would be tight. Once the flight was underway they announced they'd been able to reroute to save us some of that time. And the Alaska Air/Horizon connecting flight was also delayed, most likely to accommodate this large flight. The aircraft is wonderful--the plugs for devices at every seat plus free entertainment piped to our devices really helps to pass the time."
Cons: "Person announcing the boarding needs some enunciation lessons. She spoke too quickly and on top of (or below) other announcements and even kept talking when she was doing something beneath the podium, so no chance to read lips."
Pros: "Excellent experience all around on all flights."
Cons: "Flight was delayed as incoming flight was late"
Pros: "Professional flight attendants"
Cons: "N/A"
Pros: "I was in first class so that's the better experience. I would have been even unhappier in coach."
Cons: "Seat, despite being first class, was not comfortable I asked for a blanket before takeoff and was told there aren't any on board. No blankets for an 8 hr red eye??? No pillow either. Flight attendants never asked if I wanted another beverage after initial service. It was an 8 hr flight. The first class meal was a tiny cheese plate. I was starving. For a $900 1 way ticket, I expect more of this airline Flight attendants seemed like they didn't want to be there. Wasn't feeling the love. it was a 12:30am flight. We are all tired, but c'mon. Smile a little."
Pros: "Everything"
Cons: "Nothing"
Pros: "Friendly staff"
Pros: "Very friendly crew. The airline also offers a little more leg room than other airlines"
Cons: "Small crowded terminal at O'Hare made boarding seem chaotic"
Cons: "Flight was delayed."
Pros: "Friendliness"
Pros: "Flight on time. Great service"
Pros: "LOVE the free WiFi for messaging."
Pros: "Free movies!"
Pros: "First off Bonnie at the boarding gate was phenomenal , She has an amazing disposition ( especially at 5:00 in the morning ) she greeted each and every customer by name and with a smile ! Our flight was delayed for 2 hours as we sat at the gate while problems were fixed . The Captain made sure he kept us informed as each problem occurred and was fixed . The rest of the flight crew remained patient and attentive , which of course kept all the customers onboard calm and patient as well . My daughter just moved to Seattle and if this is the norm for this airline I will continue to use them for my future visits ! Elizabeth"
Pros: "Due to the bad weather, the turbulence was terrible. However, the flight attendants were nice and their job were very efficient."
Pros: "Efficient and comfortable"
Pros: "The plane was very spacious and had a lot of leg room. The outlets were very useful."
Cons: "Nothing to complain about."
Cons: "My initial flight was at 0800; I got to the gate before 0800 and was told I couldn't board the flight even though it was still at the gate and was still before the flight time. I had to pay to rebook my flight, spent over $200 in rides to and from airport, had additional parking fees and was several hours late to work. I have many family members who work in flight service so I understand that employees don't like to re-do paperwork; however, being there before the flight time and being denied cost a lot of work time and money. I have always had great experiences with Alaska so this one was quite a disappointment compared to their usual great service. :("
Pros: "Very accommodating staff"
Pros: "The staff was extremely pleasant. Plenty of leg room. Departed on time and arrived ahead of schedule."
Cons: "Nothing."
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: "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: "New equipment"
Cons: "Sparse food."
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."
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: "Got there earlier than expected. Staff didn't charge me for one drink"
Pros: "Boeing plane was so comfortable and modern and new."
Cons: "I got a "faux" window seat and felt very claustrophobic and misled."
Good service
Arrived 20 minutes earlier,
Wi-Fi on a much delayed departure would have been good
Boarding took a long time. Taking off took a long time. I spent over an hour connecting, disconnecting repeatedly from the Wifi just to watch the last 15 mins of the movie I watched on my first flight. Wasn’t offered ice with my drink. They passed me twice to throw out my garbage. And the guy next to me had his arm in my ribs the whole time.
Pilot was a madman. The landing was the worst I've ever experienced. He seems to have misjudged the ground and hit the runway HARD. My back hurts and my inside organs are sore from the impact. Then as we were taxing to the gate he repeatedly slammed on the breaks so we jerked forward each time with enough force to tug on the seat belt. All the passengers were asking "what happened? What went wrong?" Pilot had an Australian or New Zealand accent.
It was a smooth flight. Nothing untoward happened
The 2 hour delay stunk
Pros: "Flight canceled without notification"
Pros: "Trip was ok"
Cons: "The flight was delayed 1 hour"
Pros: "Kosher snacks! Thank you. Screens and outlets at every seat. Safe, controlled Covid protocols including de-boarding. Excellent!"
Pros: "Delta flight took extra precaution to keep all passengers safe before during and after the flight. They communicate effectively during the flight. I will be flying Delta again and again."
Cons: "The trip was great"
Pros: "The crew very professional. My flight was on time."
Pros: "Super friendly and helpful with connections."
Cons: "The music on the plane was a bit much. Lol"
Pros: "Flight was on time and crew helped find a place for my violin. Even though I was early to the gate, they also helped me update my seat before the new flight crew arrived."
Pros: "Nothing"
Cons: "We were traveling international in Twitter after contacting we were told we can carry one checked baggage but then we were not allowed and at gate they didn’t know the procedure and repeatedly checked our passport Poor customer service"
Pros: "Short lines"
Cons: "Seating arrangements"
Pros: "Comfortable plane due to few passengers"
Cons: "7 hour delay after flight postponed."
Cons: "I would ask that the gate does not share in detail reason for delay in seat assignment is related to getting a family sitting together when the basic rules should apply unilaterally."
Pros: "Got to my destination without any issues"
Cons: "Seats/seating area are too small, and I'm not a big person."
Pros: "No"
Cons: "The flight was delayed almost 6 hours, the crew was rude and the “comfort +” seats had very little leg room ."
Pros: "All good."
Cons: "Price"
Pros: "The flight was on time, the crew was pleasant and looked like they enjoyed working in the air."
Cons: "Our second time on a 787 Dreamliner across the Atlantic as about the same as the the first. The seat pitch is very tight so when a passenger reclines into the next row the seatback nearly touches your face. The Dreamliner seats seem to be very hard and it's difficult to get comfortable."
Cons: "No AC for an hour before takeoff - very uncomfortable. Audio for tv did not work."
Cons: "Seat assignment for me and my traveling companion was done at gate. We had to sit in 2 different rows."
Pros: "Helpful"
Cons: "More print media to read on"
Pros: "Crew was great."
Cons: "Couldn’t hear/understand the pilot"
Pros: "Flight attendant in first class was amazing."
Pros: "The boarding was fast and very well handled."
Cons: "It was delayed"
Pros: "N/A"
Cons: "Chinese Eastern did not try to help and solve my problem."
Pros: "There was a bit of a mixup in boarding the plane but otherwise the flight was good. There was no entertainment system on this short flight. The flight attendants were very pleasant & efficient. They only served snacks on this short flight but were very good at ensuring everyone had at least one or more beverages. The premium seats were very comfortable ."
Pros: "Short flight"
Cons: "Flight attendant was not willing to go above and beyond as he stated he would. My husband asked for a coke and the flight attendant told him he could only get water."
Pros: "It was a smooth boarding, flight and exit out of the plane."
Pros: "On time departure/arrival despite weather in Atlanta. Always a fan of free messaging and choice of snacks."
Cons: "Delta needs to invest in their gate area at ORD. Understand it’s not a hub but it’s a key business/leisure destination. The MD-80s are ok for a short hop but over 1 hour unless you’re in Comfort+, it’s tight."
Pros: "Snacks, cleanliness and crew"
Cons: "N/A"
Cons: "From the begging they changed the flights for something totally different. It was a 14 hour trip. Awful"
Pros: "Nothing"
Cons: "They take them forever to find me another fly ,make miss my other fly, my work my time and my sleep"
Cons: "Entertainment app from Go Go didn’t Work."
Pros: "I was given a complimentary upgrade."
Pros: "The crew and pilot were absolutely amazing."
Cons: "This is my 3rd delta flight in a row that has been delayed. I understand these things happen, just extremely frustrating."
Pros: "I needed to run real fast to the connection flight and gladly got there on time."
Pros: "The service was amazing , the staff was honestly friendly and nice"
Pros: "Great service, nice agent friendly"
Pros: "Very friendly and professional gate agent and flight attendant"
Cons: "I was unable to fly at all due to a spelling error on my ticket. The airline refused to alter the ticket. Worst experience of my life, ruined my Christmas"
Pros: "Very nice flight and attentive staff. Enjoyed the view of NYC as we flew up the East River, then looped over Nassau County to approach LGA."
Cons: "The male flight attendant who handed out the complimentary drinks and snacks acted a bit strangely. I was very thirsty, and I asked him if I could keep the rest of the can of soda. He neither said yes nor no, but rather completely ignored what I said and just poured my drink and moved on. I was a mildly annoyed, but figured maybe it was policy and he was shy and didn't want to debate the matter. When he took care of the older couple behind us, however, things got really strange. He asked them whether they wanted pretzels or peanuts, but they misheard him and asked for a ginger ale. I happened to know that he did have ginger ale, since my wife had just gotten one, but rather than just pouring the old folks a drink, he repeated himself. "Peanuts or pretzels?" They misheard again and asked him whether he had a diet ginger ale. Again, rather than just pour them the drink, he repeated himself. "Peanuts or pretzels?" This went round and round a few more times -- like a poorly designed computer UI that refuses to accept anything except the correct input -- before the old couple finally figured out the disconnect and picked their snacks before their drinks. Very weird."
Cons: "Layover"
Pros: "The movie I watched was pleasant, although I had trouble hearing it because of the situation described below."
Cons: "There was a family seated behind us with several crying, loud children. We were miserable. Even my headphones with a Mozart sonata cranked up to loud did little to mask the noise. Probably not Dela'a fault, but the crew did nothing to mitigate the problem."
Cons: "Plane was sat broken at gate and needed part to be flown in. 150 minutes delayed. Not acceptable."
Pros: "I missed my flight for the first time and I was having a complete meltdown at the check in desk until the sweetest agent said "oh no worries sweetheart, let's find you another flight back home"... It seems so simple but with the morning I had, this simple act had me in tears! The kindness and patience she showed me was amazing and definitely the reason I will always fly Delta to any and every destination they are able to take me! <3"
Pros: "The crew was nice"
Cons: "It was over crowded, the person in front of me spilt their entire coffee on my bag and with everyone wearing masks no one can hear you. He didn’t apologize and it was a mess. When I went to get my luggage they just tossed it and then entire bag opened up. My luggage was not over stuffed nor was it even close to the weight limit. Everything flew out of the bag when it came down the carousel. There was also no option to upgrade or even pay for a first class ticket- looks like I’ll go back to flying American."
Cons: "Engine was super loud on takeoff - to the point where passengers were looking around worried that something wasn't right. Eventually it seemed to be switched off once we hit the clouds and we seemed to sort of coast quietly for a minute or so - also alarming to everyone judging by the non-verbal behavior that suddenly everyone was exhibiting. Then it came back on again but only at half the volume. Nothing was mentioned about it by the captain or crew so I spent the rest of the flight wondering if the engine was going to give out part way through the flight."
Pros: "I liked everything was excellent"
Cons: "There was a 10 minutes delay"
Pros: "Nothing!"
Cons: "Kayak sent me a message that our connecting flight out of O'Hare was boarding at gate B5. However, checking the monitors in the terminal showed the correct gate was B21, which is on the opposite end of the terminal. I don't know why Kayak had the wrong information on this. We barely made our connecting flight because our starting flight was over 30 minutes late, which was United's fault. This made rushing to the correct gate for our connecting flight all the more stressful. No time to stop at the bathrooms or pick up something to eat. Both United and Kayak let me down on getting back to Hartford. We arrived at the end of boarding with no room left for our bags in the overheads so we had to check them and pick them up at the carousel. A totally BAD flight experience."
Cons: "Placed in middle seat with no options for isle or window due to my ticket. No problem with that if the people next to me were not so big. Young woman to my left by window was tall and broad and slept but took up all elbow and shoulder space. Guy to my right was very obese, sweaty so kept wiping his neck, head, and face with a cloth. Also had terrible body odor. I spent the entire flight in a narrow middle seat, hunching my shoulders due to lack of space. Both people taking up some of what little room I had."
Pros: "United Airlines Flight 202 Left on time. It was a Boeing 777 so it had a lot of room."
Cons: "The flight attendants seemed focused only on the small First Class section and rushed through everything in the Economy Class. They rushed through the "Food Service" and didn't want to answer questions about what is on their menu. The menu was removed from the magazines in our row. Fortunately, we brought our own snacks. The Economy CLass cabin had a terrible odor. It really smelled. Maybe they should clean the plane once in a while. United Airlines ALWAYS has issues with entertainment. You MUST download their App to your cell phone. Then, they allow you to connect to their entertainment system. If you don't, you cannot access WiFi without paying $26 for the flight ... the WiFi access is inconsistent and limiting and doesn't always work so the download doesn't always complete. This was a nine hour flight from Hell. I think I prefer Frontier Airlines. Although the airlines make you pay for everything now, at least you expect some attention and food options and a plane that doesn't smell. It was nauseating. Don't even ask me about the "Miles" that they keep screwing up ... RAY HANANIA"
Pros: "TV and movie choices should be according to 2018 instead of1980. Also TV should be from running Era"
Pros: "Captain and crew were brilliant, kept passengers informed throughout as to the delays, as a result all passengers were patient and understanding. Not much more could have been done to improve the experience as the snow and conditions at Dublin airport were out of their hands."
Pros: "Nothing."
Cons: "I was exiting your airplane bathroom and my wife was entering when the flight attendant placed her arm in front of my wife and said, “I’m sorry but I’m working so that means I have dibs on this bathroom.” She then entered the bathroom and shut the door on my wife’s face. I was furious and speechless to witness such frank rude behavior and horrible customer service. I would like to think that United Airlines prides itself on better customer service than this. My wife and I have other choices when we fly and we will certainly think twice before we fly United Airlines again."
Pros: "My husband and i we want to seat next to each other"
Cons: "1) Chicago O'Hare Airport Airline staff very rude. 2) from Los Angeles to Chicago my husband and i are not sitting to each other. My husband is upset. 3) from Chicago to Los Angeles my husband and i are not sitting to each other. It happened again. Very disappointing. We think the airline doing this intentionally."
Cons: "The flight from Chicago to Moline was delayed over 3 hours due to an engine issue. We were delayed to board, then once we were boarded, we sat on a cold airplane for over 30 minutes in sub-zero temperatures in Chicago. Maintenance was called to start the engines externally but the starter machine wouldn't work. Finally, we were made to de-plane. We sat for over 30 minutes waiting on information. Never received meal vouchers. No snacks or water was given during the wait. The steward was very nice and helpful but the gate agent was horrible. She seemed "inconvenienced" when you went to ask her questions."
Cons: "The flight staff was rude, the wrong gas was put in the plane causing a delay, I missed my connection because of this where they wrote it was delayed because "it was snowing in Savannah" which was a blatant lie, but made it so they did not have to help me in any way since their delay was "weather" related. They could not get my to my destination until noon the next day which forced me to buy a new flight on Alaska air. My flight on Alaska was absolutely fantastic and I regret ever buying any United flight and will not in the future."
Cons: "Our plane was defective so had to be replaced. This is fine, I certainly am willing to wait for a new plane if it means not blowing up over the ocean. The problem was how little the attendants at the gate communicated the situation to us. What should have been a brief layover became a 12 hour nightmare. The gate attendants did finally issue meal vouchers but they waited until 10 minutes before all the restaurants closed and only issued $10 a person. This is enough to buy a hot dog at an airport... We were told there wouldn't be any rescheduling of missed connections until we were "airborne". This resulted in mass panic and confusion upon reaching our destination. We were told to go to the service desk, half an airport away, but once the entire passenger contents of the plane arrived at that far flung service desk, we were mostly turned away to seek help at individual gates. This lack of communication meant I missed the next next available connecting flight and now have a further six hour layover. I understand accidents happen and planes can break down but the nearly complete lack of care and customer attention is, frankly, disappointing. I've now had nearly an entire day added to my travel time. If I'd been willing to loose that time I would have paid $600 less for my ticket. United finally offered a token of their appreciation : a $100 e-voucher. I have spent more than that on food and coffee in airports for the past two days while trying to survive until my next connections."
Pros: "My television screen in front did not work. There were no images and the sound was very bad. So I could not listen to music either."
Cons: "The airline was generous with luggage allowances."
Pros: "The crew The entertainment options The power options The drinks"
Cons: "10 minutes earlier and the food would have been better. Then again, 10 minutes earlier and wouldn’t have made flight."
Pros: "Crew help and service"
Cons: "Lending was bumpy. , Internet was not Working and no entertainment chenal as well"
Pros: "The flight from Frankfurt to Chicago arrived late, had to collect bags and clear customs which delayed transfer, had to go from one end of the airport to the other on a train which operated very slow which delayed transfer, had to then clear TSA security checks which were very slow and again delayed transfer. Moving at the max speed we were capable of, we arrived at the opposite end of the airport too late to board and were left behind. United was not very sympathetic, although provided ticket for next morning flight. The entire experience was very disappointing following what was a decent tour of Italy."
Pros: "The only reason they have two stars instead of one is that the flight crew was good, and flight in general was ok. Also United service counter went above and beyond to help me with my situation, and I am grateful that they were able to rebook me on a new flight and check in my luggage without issues."
Cons: "There was no one at SAS service counter... I had to Google my flight number to find out that I actually had to check in with United since it was actually a United operated flight. Why was I not informed beforehand?? My itinerary said that this is SAS flight, how was I supposed to know that i was supposed to go to United?? Because there was no one at SAS counter, I had no one to ask, I ended up waiting for the counter to open for an hour. When I found out I had to go to United, it was already too late for me to check in so I ended up missing my flight. Thank god for the agent at United however, who helped me rebook my flight and check in my luggage."
Pros: "Economy Basic check-in was easier than I'd expected it to be, security was quick and seamless. Once on board the aircraft, the flight crew kept us informed about possible weather issues (e.g. turbulence), including the approximate time to expect it, how long it might last, and that it would probably preclude in-flight beverage service. Flight attendants offered to provide one-at-a-time beverage service to those "really in need of a drink." I thought that was pretty gracious under the circumstances, and was happy to see that passengers didn't take advantage of the option :-). Looks like United is doing its best to counteract its recent negative publicity. Well done!"
Pros: "It got us from a to b but not much more to be said!"
Cons: "The idea of the entertainment system broadcast to your hand held device is fine - it didn't work for me though."
Pros: "People were courteous as expected but as usual the 1st class took precedence. Big deal they pay extra for what, not to eat 1 ounce snack foods and cans of soda."
Cons: "The room and the food was horrible. Seems like every time I take a flight people get stuffed into planes like sardines. Also the food selection was nonexistent. There was not enough qty for each person on the flight and the food choices are subpar and very expensive. If u ask me with the exorbant cost of flight to include now the cost to bring luggage is horrible. What happened to the days when airlines actually cared for their customers. I guess those days are long gone. I have been in he military over 17 years and not once have I received a courtesy upgrade to 1st class and I have flew over the world. Guess it's all about the money. And have to pay for entertainment....go figure and why isn't there outlets on every seta in every row. Is that too much to ask!"
Pros: "Flight was short."
Cons: "I was not informed about the delay until after I checked my bag, otherwise I might have chosen another flight. I was informed that though I could possibly change flights, my bag might not. I have the UA app, and did not receive timely notification. Free WIFI would have been nice as a compensation. A 4 hour delay means I miss my bus and extends my travel time significantly, one more night away from home. You did offer $50 of mt next UA flight for the next year, but I don't fly that often. Considering the reason for the delay was they were waiting for a plane was frustrating."
Pros: "The fact that we got there safely."
Cons: "Took them 90 minutes to fix a seat belt because they kept bringing the wrong part. They got it right the third try. The cabin crew sat in the back and chatted for an hour while we sat at gate. Not even a glass of water offered. Then we were diverted to Pittsburg because of weather and sat for an hour. Again no water offered. So on 5 plus hour flight crew went around once. The final straw was they blamed weather for the delay when in fact it was not being able to find the correct seat belt in due time."
Pros: "The flight crew seemed worn and a bit surly. They ran out of two of the meals and the one I got was oddly seasoned but it was warm. We sat on the ground quite a while while they fixed the PA system with no water then there was a women they'd let on the flight even though she had a different destination - supposedly they spent an hour looking for her bag on the plane. Do you hold up a whole plane load of people that got on the right plane for the woman that didn't and how come when they checked her ticket - no one noticed?"
Pros: "Staff at airport and cabin crew were mostly nice. At airport, the ticket agent helped correct a mistake and was very helpful."
Cons: "There are TVs on the backs of chairs where they advertise that you can pay to watch shows or movies and play the safety video. That would be fine if you could just turn it off once that's done. But it was too hard to turn off, and after the safety video, they played three ads (you couldn't turn the ads off). At the end of the flight the tvs camenon again. It was also a night time flight - how can you sleep with the screen on. Also, the seat space seemed smaller than usual so the screen was in my face. I hated this flight."
Pros: "Nothing!!! It was handled in a terrible way"
Cons: "The way they didn't care"
Pros: "The crew was exceptionally friendly and helpful. Water and drinks were offered regularly. For those who had the app there was inflight entertainment. We paid for plus size seats and had enough leg room."
Cons: "I believe that on the long flights built in entertainment screens should be standard. Most people did not have the app and many spent 8.5 hours without anything to do. Food is not offered on this long flight unless you pay for it. You must walk to the very back of the plane where the food is in warmers. I got a hamburger and it was a bit dried out. Could have been worse...just hard to handle since tomato, lettuce and condiments were on the side. A larger person sat next to me and took use of the armrest between us which made me feel like I lost 4 inches of my personal space."
Pros: "Seat assignment"
Cons: "I'm not a pilot but I've flown enough to know what turbulence is. I was one of the first to board and asked the flight attendant if there was food for purchase or any type of snack as my blood sugar was so low. I was also in pain and needed to take my medication. It was a 40+ minute flight however when one is handicapped you are at the mercy of the person taking you to the gate it's not like you can stop and look for a place to eat. It wasn't until we were almost at the destination we received a plastic cup and offered a sip of water. I sat right in front of the flight attendant and she could see my discomfort yet didn't offer a bag of peanuts or a drink"
Pros: "The older planes of United Airlines could use some remodeling. The entertainment system with controls in the middle of the arm rest where the elbow rests is such a bad idea, didn't even bother with this crappy unintuitive system. It was annoying and flashy with bright advertisements or something popping up on a night time flight just sooooooo annoying, turning it off was not intuitive and had to ask the flight attendants how to turn it off during their very busy work of handing out packages with five miniature pretzels and drinks to the passengers, was happy to get a whole cab of juice to myself though."
Pros: "Crew. Aircraft selection."
Pros: "Other then they got me there safe, I dont think there is anything I liked about this flight. Pilot did a decent job, there was lots of turbulance so nothing they could do about it and I made it safe."
Cons: "Plane from Chicago to Savannah was small. I was all the way in the seat not slouching and my knees were crammed in the set infront of me. The arm rests were digging into my thighs as well. Im used to not much leg room but this was a first for how crammed in I was into a seat, Im 6'3" & 270lbs. Ive probably been on 50 different planes over the years to give you some perspective of my experience flying when I say this was a first and a very uncomfortable plane. The plane to take us to Savannah arrived so late it pushed my flight back by like an 1.5 hours from what it was supposed to be."
Pros: "The crew did what they could and we're professional and curious, but there wasn't a ton to like about this flight"
Cons: "The flight was delayed. Ok, that happens sometimes and it annoying but part of air travel. The real kicker was that once we were on the airplane, they announced that seatback entertainment and wifi were not working, so there was no entertainment on the 4hr+ flight. Additionally, because the seatback entertainment wasn't working, the ability to control your own reading light was disabled, so the cabin lights were left on the entire late-night flight, making sleeping quite difficult. I understand that sometimes these things happen, but there are ways to mitigate- the gate agent could've told us that there would be no seat back entertainment while we were waiting at the gate delayed so we could've downloaded something, but they chose not to for reasons I can only hypothesize. Combine all this with the terrible 3-4-3 seat configuration and you're left with a terrible experience. Will never take this particular flight from Chicago again. It was cramped and one of the worst flights I've taken in recent memory."
Pros: "I loved how easy it was to book the flight."
Cons: "I cancelled my flight within 24hrs and received no refund because I booked through priceline. However, there was no restriction or clause listed on the ticket stating that I had to cancel through priceline also. It really should not matter who I cancelled through, if I canceled within 24hrs the refund should be given. Also, the debits from my account said United as well as priceline taking me to United's web page to make the purchase. So of course one would think cancelling through United's site is appropriate. I'm very disappointed in United and will consider all other options (Airlines) before booking with them again. PS - United customer gave me the run around for 3 days knowing that it was their policy and they were the company who's keeping my money. Absolutely ridiculous."
Cons: "several people assigned to the same seats, mine included. lots of last minute moving around."
Cons: "This airline is so beyond awful. American has the most janky planes, uncomfortable seats, and worst service on the plane. I had to beg the flight attendant to get me a wine because I was asleep when they came by and missed them by not even a half hour... She acted like it was so hard and it took asking 4 times and finally just asking another person. I was so annoyed. They also have shitty food selections per usual. Who chooses those snack items?! They clearly have no taste. I was miserable the whole flight. I usually am not a miserable traveler so this isn't just me being negative, I seriously may write one review every few months, only if something is really good or really bad. The fact that I'm even taking the time to write this says a lot!!!"
Cons: "I had a flight from Los Angeles to Cleveland with a stop in Chicago on December 29, 2016; however, both flights were delayed. I am contacting customer care for compensation due to a severe delay for the departure and arrival for my flight from Chicago to Cleveland (Flight 786). I also wanted to report a very disappointing experience with the representatives at 1-800-864-8331. I was supposed to arrive at Cleveland, OH (CLE) on December 29, 2016 by 7:30 PM. However, it was closer to 11:20 PM when we finally arrived. The flight was delayed over an hour for departure when they announced the plane was not even ready and present at the gate. Due to this delay, we were not able to land on Cleveland, OH (CLE) because of snow on the runway. We circled Cleveland for roughly 40 minutes and then got redirected to the Detroit. We would've avoided the snow if the flight departed on time since the snow did not hit Cleveland until the delayed flight was airborne. We then landed in Detroit and spent another hour and a half in Detroit. At this time, I called the representatives at United and requested a refund. The representative completely understood my situation and said I would be refunded the full amount to my original payment method. She also assured me that I did not need a case number and that other representatives would be able to look up this information through my confirmation number. This was not the case when I contacted United again to see the progress on the refund. They said there were no annotations and that they could not provide a refund. They advised me that the previous representative had lied to me. While the flight experience caused me to miss the rehearsal dinner and bachelor party for a close friend I served with in the Army and almost caused me to miss the wedding, I feel very cheated and trashed for being lied to by your employees regarding my refund and its validity. This experience has left a very bad taste regarding United Airline's integrity and values."
Cons: "My flight was delayed by an hour and a half. That's the amount of time I could have spent to drive home to Milwaukee. I stuck around because there was no indication of a flight cancellation. I would rather hop on a 15-30min flight than go through the hassle of renting a car. BUT the flight did get canceled, the next flight was completely booked and the next flight out after that was at NIGHT. I arrived in Chicago in the morning. The gate agent told us all to head to United customer service. There I received RUDE, poor excuse of a "service" only to be told they don't give refunds at the counter as we were told by the gate agent. So do that on your own time. THEN I had to buy my bus ticket and spend 1.5-2hrs on top of already waiting 1.5hrs for the flight that got canceled. HORRIBLE. Will never fly United again. Did i mention upon my arrival home I found out American was WIDE open seat wise to chicago?? And no one checked for me!"
Pros: "-Complimentary Snack and beverage -Can pick your seats when booking -Changing Tables in restrooms -Entertainment options -Early boarding for families with small children"
Cons: "-Free Soda but charged for water -Had confirmed seats but then our party with 2 toddlers got split up -Semi convenient( rather small could hardly fit a 1 year old) changing table but then flight attendants threw a fit when a stinky diaper was changed in there. -Had to have special programs on device to even play anything, thought I had everything on for return flight to watch movies but nope still needed something extra Wifi only works for United App and Website -Waiting in the shorter line to preboard with our 2 toddlers only to be cut off by a Global Travel Program(?) family with 15+ people"
Pros: "Arriving safely at home."
Cons: "Our gate was changed multiple times with absolutely terrible communication. The computer system had gone yet and everything seems extremely disorganized. There were even flyers getting on the plane to TX when they were traveling to other destinations because of the lack of communication and the crew not throughly checking. The seating was the smallest space in all of the other airlines I have flown. The crew was less than friendly and yelling down the aisle about buying snacks and other drinks although it was a late night flight and many people were sleeping. Overall, it was an uncomfortable and frustrating experience. Luckily the flight crew had a smooth flight and got us safely to San Antonio. Only positive about the experience with United. This was all taking place along with our flight being delayed with out the monitors at the airport being updated and no notification via text or the United app."
Cons: "The difference in entertainment options between different United flights is frustrating. Unlike some flights, which offer a bunch of free movies and shows you can watch on your phone or tablet, this flight offered a small selection of movies I could pay $8 for access to, which started at pre-determined times so you might pay for them and not even be able to catch the movie from the beginning. My original flight offered an outlet to charge my phone and a fairly large selection of free movies, so I watched 3 movies and the time went by quickly. My return flight did have an outlet, but I didn't want to pay for a bad selection of movies that I couldn't pause or start from the beginning, so it felt like a much longer flight."
Pros: "Captain had apologized many times about the delay. I appreciated that. . Crew attitude towards customers were way better than my first leg.( Beijing to Chicago). I wonder why. Boarding took long time. Many people had no overhead bin for their carry on. I don't have one so I Just watched them. They serviced water and a tiny snack. One man asked if they have something to eat. He was given a bigger bag of snack, free, usually he had to pay. I guess its due to the delay. Waited a little longer for luggages. But I was happy I arrived Boston safe before midnight."
Pros: "I like that we finally made it!! 130a.m."
Cons: "This by far is the worst flight I have ever been on! It's starts off delayed... Fine! They get us on board the plane and we sit and sit without much info being given to ppl on flight! Then we are told there are mechanical issues and it won't b long before we leave... Half hrs goes by and they tell us it will be longer so for us to exit the plane.... Which turned into a 45min wait to finally tell us that we were waiting now on a new pilot to fly in from where ever he was to finally take over our flight , which didn't leave ORD till 1230.... Which was supposed to had left ORD at 930.... We finally get to PHX at 130 a.m. When were supposed to originally land n PHX at 930 mountain time! After all of this confusion and just bad manangement of time... We didn't get any apologies any kinda of compensation for time lost... Just a have a gud day! I'm pissed will Never fly with United Airlines and will tell others to also not fly United!"
Cons: "My boarding pass was not scanning which was holding up the line. A second person came over to approve me getting on the plane. That person made me check the size of my carry on bag, which had gotten bigger from some things I purchased in the airport but was just a touch too large for their sizer. She attempted to check the bag meaning I wouldn't have it until my final destination, which I was NOT ok with for two reasons. One was i had a 3 hour layover after this flight and needed work materials inside. The second was i was on a time crunch to get my ride at my final destination and was only traveling with carry on. She was very rude and insitant on it fitting inside the sizer as she stood over me with the tag to check my bag. I managed to take some things out that I moved into my backpack, which meant I had to awkwardly carry my blanket and travel pillow onto the plane. The most frustrating part was when I got on the plane, it was oversized top carryon bins, so the extra inch my bag grew would have been fine. Because of the time it took me to rearrange, i was the last one on the plane and all the bins had been filled with tiny second bags, but a few people on the plane had seen what happened and they rearranged a space for me. Also my video screen was broken and everyone else's worked. And there were two screaming babies around me the whole flight, but that is no one's fault."
Pros: "The flight itself and the crew were fine."
Cons: "The flight was delayed by weather but still on time for us to make our connection. But boarding was delayed. Finally, the gate agent announced that they were repairing an overhead bin door. This took approximately twice the announced estimated time. Even so, we arrived at the gate with enough time to make the connection, which was 4 gates away. Did the crew ask people to let those with close connections get out first? No. Did the crew or gate agent communicate to other gates that we had arrived? No. We got to our connecting gate 6 minutes before the scheduled departure. They had closed the door and would not board us. Two people from our plane made it to the connection, so they knew we were coming. But 5 of us who were seated a little further back arrived minutes later. We made it onto a later flight. We also adopted an elderly passenger in a wheelchair, who would have been left by himself at the next gate for 3 hours by United if we had not taken him with us. We all got on the next flight, but only with some work."
Cons: "Departure was delayed for five hours. Gate changes 4 different times to opposite sides of the terminal. Weren't told honest reason of the delay until two hours in. They boarded half of the plane and stopped when the pilots radioed in that there was a severe hydraulic fluid leak. Updates were supposed to happen every thirty minutes but more than three times they were longer than thirty minute intervals and at one point more than ninety minutes without an update. The representatives at the Chicago gate told us we were all set then the rest of the passengers boarded the plane. The pilot said they were waiting on maintenance paperwork to print off but then we waited an extra hour at the gate on board while we could still hear very loud tests of the hydraulic system. Once we finally left the gate and headed out on the runway for takeoff we stopped just before takeoff and the pilot said we were waiting on PAPERWORK AGAIN! This was another 30 minute delay and we finally took off. We were supposed to arrive home at 10:00pm and instead arrived at 3:00am..."
Pros: "Seating was very nice in Delta select, lots of leg room!!!"
Cons: "There were 3 flight attendants on this flight and two of the three were great. One however was the rudest woman I've ever met. Her favorite word was "no" and she talked down to everyone, including her fellow flight attendants. I really wish I had gotten her name but when I asked her, her response was, "why?" I was so fed yo with her I just said forget it and avoided her. I understand people have bad days but I have a feeling this was more of a personality issue. She acted better than everyone else. It really only takes one person to ruin the whole flight"
Cons: "They held us on the plane from Indy to Chicago for so long that most of us knew we were going to miss our flights. I ran all the way to my gate to discover that the plane took off 10 minutes earlier than it was supposed to. I was told there were no other flights to LA and I would have to get a hotel until tomorrow. I was only going to be in California for 2 days so every second counts, so when I became upset the man checked again and found me a seat on a plane that took off in an hour. I was grateful but at the same time I was kind of displeased that he didn't offer that to me originally."
Pros: "Punctuality"
Cons: "Food. It is a very long time and there no food enough"
Pros: "-Pounctuality"
Cons: "- Horrible food; - Very old airplane. The oldest I ever flew; - The entertainment system was horrible and not worked. We came the whole flight without having access to anything, neither the map of the flight."
Cons: "I am almost always cold. Not so on this flight. The temperature on the plane was so miserably hot that I had sweat pouring down my face. Everyone around me was trying to open their air vents to get more cool air and/or fanning themselves. I asked the flight attendant about it and he said that the plane was just old and it would cool off eventually. It did, about 20 minutes before they cut the air down again for landing. By the time I got off the plane I was nauseated from the heat and stale air. It will be a long time before I fly United again if this is any indication of the condition of their planes."
I liked the Flight attendant and our seats. Will never use frontier again
Delays all the time!!!
Bad service over charge for everything and always late
My 1st time flying and I was very please. Staff were excellent.
Frontier cancelled it without any explanation…and no support..
Frontier Airlines got me to where I needed to be with no extra services that I didn’t pay for. They even got me there a full hour early.
It was very cold on the flight and where I landed.
Great price! Clean and efficient.
Uncomfortable seats
Too many announcements. There was no food or entertainment but there was no n/a option
Pros: "We missed the flight due to parking difficulty We came to the airport at 1:10 pm and flight supposed to leave to Ontario at 1:30 pm I requested a flight change or refund But neither refused Please help us to get refund or credit for the next flight Sudath Edirisuriya 916-751-8219"
Cons: "Please provide help to us"
Pros: "Crew"
Cons: "Not delayed"
Pros: "Nothing"
Cons: "Terribly uncomfortable seats"
Pros: "The crew was very friendly"
Cons: "The termianl could use an update"
Pros: "I got back on time and smooth flight!"
Cons: "Recliner sitting"
Cons: "Very nice. Smooth. Fast"
Pros: "Yes"
Cons: "Thanks , perfect , not a thing"
Pros: "Good service"
Cons: "Entertainment and better seats"
Cons: "Entertainment on long flight"
Pros: "Overall a quick flight crew was great always picking up trash it was clean."
Cons: "Only thing I hate and probably will never fly frontier again checking my bag was 50$ and the seats are absolutely uncomfortable I will pay a little more and fly with someone else everytime I fly because after bags it’s not worth it"
Pros: "I like that the plane was on time departure from Ontario in arrival and also on departure from Orlando to Ontario"
Cons: "Some type of entertainment on the plane"
Cons: "Seats are tough but price is right"
Cons: "Nothing . Nothing at all . Considering I didn’t have to drive, ride a bus , or train . And can get from one side of the country to the other in the time it takes me to get half way through a work day. I’d say any small inconvenience is still well worth the price. And hats off for the TSA . Well done"
Pros: "On time, clean."
Pros: "n/a"
Cons: "n/a"
Pros: "Inexpensive fare. CLEAR and TSA-PreCheck for security screening a big help at very busy Denver airport."
Cons: "Bag check is expensive at $40/per. Nickel and dime passengers for everything. Fare was cheap so I guess it was worth it. Online check-in was a big pain, since Frontier had incorrect/missing information (name-was that Kayak's fault or Frontier? I don't know.). When I attempted to correct it, they changed my fare to full price. Allowed check-in to timeout and eventually successfully completed without corrections so that fare was unchanged."
Pros: "Boarding in zone one"
Cons: "2nd most hated airline behind Spirit - they charge extra for EVERYTHING!!! Seats are hard & don’t reclibe unless you pay $20 more. Will NEVER fly them again!!!!"
Pros: "None of the self check in stations was working so there’s one very long line to check in with attendants. No effort by staff to get passengers with current flights to get to front of line. Had to convince staff that small women’s pack was a purse and not a 2nd bag to be checked in for $50. Woman in front of me had a more traditional large purse and encountered no problems."
Pros: "Nothing very disappointed with Frontiers service"
Cons: "From Ontario to Austin we were charge $50 for each carry on luggage we 1 for me 1 for my husband total $100 charge From Austin to Ontario carry on luggage was free why?Im filling complained about the airline"
Pros: "The roomy seats"
Cons: "No tv in headrest and flight attendants were not very friendly"
Cons: "Flight delayed 2 hours! Seats don’t recline in coach!!"
Cons: "We arrived very late due to the airline being run so poorly. Something about paperwork according to the pilot. Now the rental car company is closed so I have to sleep at the airport and wait till the budget opens again in the morning. Frontier should put me up in a hotel as their mismanagement caused the delay not the weather. But they just said too bad because the flight was less than 4hours late. Frontier - never again!!!- plus the seats are painful"
Pros: "Clean smooth flight and nice crew"
Cons: "Rude woman at check in counter"
Cons: "You have to pay for the carry on and seats."
Pros: "Nothing"
Cons: "Everything"
Cons: "The plane was over an hour late and they lost our luggage. I understand things happen it was not that big of deal but the lady in Syracuse was unfriendly and acted like she could care less. We ended up going to a wedding in our shorts and flip flops because we had no clothes and not enough time to purchase any. Our bag was delivered about 1am. The customer service was really pathetic. Not even an I'm sorry this happened."
Pros: "a bit better, the flight was only half full so it made the experience more enjoyable overall."
Cons: "Kinda annoying they are always trying to upsell."
Pros: "Nothing was 2 hrs late"
Cons: "Was 2 hrs late"
Pros: "The flight itself was fine"
Cons: "I used to love frontier but now everything from baggage policies to checking in feel like a huge hassle"
Pros: "The fair was low and boarding was efficient."
Cons: "The booking process was terrible online. There’s a charge for refreshments, the tray table is tiny, the staff didn’t seem happy, the seats don’t recline at all, they charge for carry ons, no outlet to charge my device."
Cons: "The fact that my checked baggage is confusing when they charged me it was only for one way. I was billed and then noticed it was only one way, so I had to re enter my credit card info twice. Seems to me they should assume I will be bringing back my suitcase and contents rather than that I would be leaving it."
Pros: "crew"
Cons: "you should be arrested for those seats"
Pros: "The fabulous front row seats!"
Pros: "Comfort seating is spacious."
Cons: "Doesn’t make sense to charge for water."
Pros: "Boarding was painless and quick, flights were on time to destination, even early. My last flight actually made up time after departing late d/t passengers taking forever to deboard. This is a super inexpensive ticket folks, if you pay attention to the fine print it clearly states you pay extra for bags to check or carry, cheaper to pay online before your flight, also clearly spelled out if you look and easy to do."
Cons: "Seats don't recline, food isn't offered, but for the price of the ticket, buy your own before boarding!"
Cons: "Seats were very uncomfortable. Could not comfortably rest head anywhere to get any rest. Couldn't even lean on the drop down trap because it was so tiny. Poorly designed. It's a cheap airline, I get that, but my goodness, it was impossible to be comfortable on a 5hr flight, especially as a red eye!!!!!!"
Pros: "Flight cancelled after 7hrs"
Pros: "The price."
Cons: "Crew not very friendly, flight delayed 5 hours, uncomfortable seats, minimal leg room, no entertainment."
Pros: "Flight cancelled"
Cons: "Unclear baggage policy until at the gate--didn't have anything said to us at checkin, then stopped for our small carry on duffel at the door. Were quoted 30 for the price of the bag--charged 45. Desk attendant was incredibly rude. Very unimpressed, have no intent of ever flying with Frontier again."
