Cons: "Choice of healthier snack"

Pros: "Nothing spectacular."
Cons: "The headrests won’t stay up. And it’s hot."

Cons: "Have rhe right to carry at least one luggage per person at no cost. Besides carry on and personal item. Tickets prices and luggage costs are extremely expensive."

Cons: "Couldn't believe the flight attendant walked around with a tray of snacks and bananas. When I asked for the banana, she said, "Oh I'm sorry, those are for First Class only". Really?"

Cons: "Denver airport is far too large for there to be such a small security check therefore it took forever and I missed the flight. Delta tried to charge me $1000 for another ticket to Albany and I decided to fly with another airline for half the price instead"

Pros: "Nothing"
Cons: "I bought a ticket thinking i bought it through kayak but I actually bought a ticket through a third party in India. Where no one spoke good English. I called the agency to find out if I needed a Visa for my visit to Australia and the told me no. So when I showed up to the airport I didn’t have the right documents and I MISSED MY FLIGHT. Also the wouldn’t just change my flight and charge me the change flight fee. They cancelled my flight entirely and made me buy a whole new ticket!!! Worst flight experience I’ve ever had and this is not my first time flying to Australia or out of country."

Pros: "Anything from free WiFi, entertainment, leg room, commentary drinks and snacks. Great service!"

Pros: "Short flight"
Cons: "In SLC they boarded by row numbers and not zones. Weird..."

Pros: "The fact that there was a screen for movie selections and a charging port for my phone and the flight attendants were super nice"

Pros: "What a city.. Unique for hell sure..."
Cons: "Nothing"

Pros: "Nothing"
Cons: "That I couldn't reschedule due to the hurricane. I got stuck in Texas because of the hurricane. They didn't want to reschedule the flight because Denver was not apart of the affected area."

Cons: "Long flight, difficult to sit that long (3 hrs plus)"

Pros: "Excellent crew and comfortable flight"

Pros: "It's a nice, comfortable flight with plenty of entertainment options."
Cons: "The coffee on board is lousy, but I'm not sure that is much of a surprise."

Pros: "We purchased economy tickets in Delta. With these tickets you don't know where you are sitting until you get to the airport. Well, we lucked out and got the Plus seats! We got free alcoholic drinks, and big plush seats! We left right on time and got there early! Overall a great experience!"
Cons: "Nothing."

Pros: "Great,I loved it!"

Cons: "I fly Delta quite often, and am usually pleased with their service, but the morning of June 23 was terrible. I got to the airport in Denver at 5:30 am for a 7:30 am flight to Atlanta, and the line to check a bag was about 40 people long. I waited 55minutes to check my bag, as they kept moving the ski priority people, and people in danger of missing their flight, to the head of the line. There were obviously not enough Delta workers on staff to process all the flights at that time."

Pros: "The moviea"
Cons: "The time of night"

Pros: "Everything else fine."
Cons: "Made me check my bag - even though ther was plenty of overhead bin space."

Pros: "I didn't like anything because the fly leat 3 hours"

Pros: "First we had a mechanical after boarding. I was rerouted through Atlanta. That flight is now delayed by 2hours. I then had to reroute to West Palm Beach instead of Ft Lauderdale. I will leave 9 hours after my original flight time and arrive 8 hours later. Just ridiculous"
Cons: "See above"

Pros: "The cabin crew serving the main cabin were exceptional. They were efficient, kind and FUN. We were an hour late leaving and 2/3 of the plane was worried about tight connections. They handled it with grace giving each person their departing gate and asking everyone to let a gentleman off with a 10 minute connection. They made the flight memorably enjoyable."
Cons: "Being an hour late isn't ideal and I understand that it wasn't their fault (the plane was late arriving into Denver. Those things happen. They still goto people to Detroit in time to make connections--barely."

Pros: "Smooth ride. Delta got everything right from takeoff to landing."

Pros: "Entertainment options"

Pros: "The flight attendants were so nice and accomadating. Even came by to refill our waters! I've never been on a flight with such friendly flight attendants!"

Pros: "Reassignment was pretty easy."
Cons: "No accommodations were available for overnight stay due to delayed flight."

Pros: "Upgraded to first class"
Cons: "No entertainment system, no power outlet...for first class this is disgraceful"

Pros: "The flight crew was great"

Pros: "Plane was clean and staff were friendly"
Cons: "The snack options were quite average"

Pros: "Excellent customer service. That doesn't seem to happen too often with airlines. Delta has been outstanding."
Cons: "No complaints."

Pros: "Flight took off on time and arrived about 30 minutes early."

Pros: "on time travel care in treating my visitors from Kenya Africa"

Pros: "The flights back to anchorage were much better than the flights out of anchorage. They were on time and everyone was very helpful."

Pros: "you still get a complimentary snack and drink"

Cons: "I had no room to move and my legs were stuck"

Cons: "Extra rules about headphones are annoying and no beverage options. Horrible terminal that does not let you get a drink before boarding and gate agent did not update boarding when it was late, so no one could venture off and get a drink of water before flight."

Pros: "The fact that the in-flight meal was as cold as the crew, and you got to pay for that coldness. Just love it! You get me right?"
Cons: "The Montreal-Vancouver route was by far the worst. The attitude of the crew was denigrating and arrogant."

Pros: "Good boarding.Easy check in."
Cons: "Food! Not appealing. Did not eat more than a few bites."

Pros: "1 stewardess was great"
Cons: "Flights were delayed. Did not check boarding passes which was scary."

Cons: "Had to spend the night in Toronto for flight delay"

Pros: "good overall...so MUCH BETTER THAN Air Canada rouge service we took from Ottawa to Venice. Rouge service is very poor!!"

Pros: "The pilot and the crew are very proffesional."

Pros: "Everything on time"
Cons: "Nothing"

Pros: "Cleanliness, crew (in general)."
Cons: "Problems with entertainment system sound seem to be a recurring problem aboard aircrafts - the jacks seem to be in bad shape in most, whether for the provided eraphones or those brought on board."

Cons: "AC was helpful arranging a delivery of the delayed luggage. But carrier was further delayed from the scheduled delivery time."

Pros: "Airbus 380"

Pros: "Crew was nice"
Cons: "Couldn't use in flight entertainment, only half a soda was given"

Pros: "We had lots of leg room unlike the Air Canada Rouge flight that we took from Toronto ON to Kelowna BC. Also very little table on the rouge flight."

Pros: "Service was poor. Attitude was less than enthusiastic."

Pros: "Nothing"
Cons: "Customer service flight rebooking"

Pros: "Leg room adequite."
Cons: "Only beverages served, there wasn't the usual snack."

Cons: "No monitoring of travel route"

Pros: "Seat availability (lots of empty seats) Entertainment system had lots of movies & music Friendly flight attendants"
Cons: "Flight attendants could be more aware of his/her surroundings. For example, I was either stepped on (as a result, being woken up) or my backpack was stepped on several times when an attendant was walking down the aisle, and neither of those things were sticking out into the aisle. This has rarely happened to me on trans-Pacific flights (more crowded, longer flights) so I can only attribute it to the carelessness of the attendants and/or the aisle width but since I think aisle width follows international standards it's more likely the former."

Pros: "Not refunds, no voucher, no credits .... But still s stupid fee of U.S 200 to pay on my Next flight using same booking Code . RIDICULOUS !! Guess other airlines want my business and my friends' too.."

Cons: "Movies and audio lacked currency, simply old and little variety."

Cons: "No good movies or music"

Pros: "I arrived early and was able to change my flight to an earlier one."
Cons: "The air hostess/stewardess was surly...and looked like she hadn't slept.."

Pros: "An Air Canada rep over the phone"
Cons: "Gate agent, zero entertainment (and no warning that we should download an app inside airport), poor food, flight attendant wouldn't bring coffee to us (made us go to the back)"

Pros: "Leg room was great."
Cons: "The pilot wasn't that good. It wasn't a smooth landing at all."

Pros: "Upgrade to premium economy with more legroom. Free movies. Good movie selection. Free checked luggage!"
Cons: "Check-in process at Denver counter rather slow. Gate information at Denver very confusing due to changes and lateness in displaying/announcing information."

Pros: "I enjoyed the entertainment option."
Cons: "Wish there were more choices for new movies."

Pros: "nothing"
Cons: "i booked a flight through kayak going from denver to milan. i showed up at the airport in denver to fly out yeserday only to find out that i was going to frankfurt germany. i am now in munich germany and never made it to milan. i was one of many people i met on the flight that also booked with air canada thinking they were headed to milan. air canada kept trying to put the blame off to my booking company. i don't know who to be ticked off at. please advise."

Pros: "Great crew. Nice airline."
Cons: "Both flights were over 30 minutes late. Otherwise they were just fine."

Pros: "We left and arrived early, the seat was surprisingly comfortable (it helped that there were lots of empty seats, including next to me), my full-size carry-on fit easily in the overhead bin, despite it being a small plane, the in-flight entertainment was always on and pretty good... everything went well."
Cons: "Only the things I've grown to expect on any domestic service (e.g., no food)."

Pros: "Better plane than previous"
Cons: "Had to be rerouted to Calgary because I missed my connection"

Pros: "Nothing."
Cons: "The flight attendants on this flight did NOT do their job. If they are there to ensure a safe environment for the people on board, they completely missed the boat. I was in row 45. Two families were on board with their 4 very young children. For the entire 8 hour flight, 3 of these children disrupted the entire section of the plane. They continuously played in the aisles, stood in the seats, kept their seat belts unbuckled, threw objects, and one blasted his iPad at maximum volume. When I asked one flight attendant to ask the family to get the child to lower the volume on his iPad (it was 4am; people were either using their ear buds, or had their screens turned off), they complied with the request for 30 minutes, then resumed at full throttle. I can honestly say, it was one of the worst flights I have ever experienced in 57 years."

Pros: "There was entertainment on board although it was very limited. All of the crew were very helpful and professional."

Pros: "crew"
Cons: "delayed due to computer malfunction, food awful, missed my connection, had to wait for 6 hours"

Pros: "Flight was underbooked so I took an option to change my seating for more space."
Cons: "I requested a vegetarian meal and was given the exact same mediocre meal for both lunch and breakfast."

Pros: "Space and meals"
Cons: "Entainment"

Pros: "The fact that I was rebooked immediately to my new flight AC-DC 705 at 8:50 am by two wonderful ladies at La guardia airport who comforted then boarded me unto a flight due to the fact that I missed my original flight. This occured due to the Airport being Unorganized! As I had checked in well before 3 hours and was on time for my original flight at 8:30 am."
Cons: "The airport was extremely packed, Unorganized and not well staffed. What I hated is that when I arrived at my original gate A7 the gentleman who boarded my original flight was unprofessional, rude, basically ignored me and said "You missed your flight !" Not even taking the time to listen to my situation or guide me in my next steps of acquiring a new flight to go to my classes and home in Toronto!"

Pros: "Comfortable and large plane with tvs"

Pros: "Everything but the size of the in-flight seats"
Cons: "Seats way too small and uncomfortable."

Pros: "On the plus side, the service was great."
Cons: "There is just not enough space in the seats! I am not a tiny person and my trip was not helped by the fact that the seats are too narrow to comfortably seat people larger than a size 10!"

Pros: "The plane was fairly modern and the seating had more leg room than many other economy flights I have taken. The flight attendants were friendly and courteous. All-in-all a very good flight. I was especially appreciative of the concessions made for skiers when it came to luggage. Also, the luggage fees were very reasonable."
Cons: "I was a bit surprised that no snacks were offered free of charge. I can understand that meals are not included in economy, but nuts, cookies or some pretzels would be nice."

Pros: "AC changed to a different plane for our flight at the last minute, so seat assignments were messed up, and we had paid extra to choose seats. So why pay extra for seating when the airline can put you wherever they want at their discretion. In addition there was a minor delay in take off while the flight deck crew had to re-programmed the avionics to our scheduled route. But we made up the time en route and were only a few minutes late. On the whole, not a bad flight experience, just the usual frustration in the process. I long for the days when flying was a pure pleasure."

Pros: "Hourly flights in a Boing 676. Comfy economy class seats with leather headrest (cleaner than fabric). Ample overhead space for carry ons. Individual TV monitors with entertainment (I prefer leaving it on flight itinerary status while reading a book). Good bretzels & tomato juice served by a multilingual flight staff. Boarding, departure & arrival on time to the second. Can't ask for more."

Pros: "Flight attendant very caring and friendly."
Cons: "Gate attendant very rude - made my daughter cry Her seat was way at the back. Baggage handlers lost a luggage strap - sturdy one 7 boarding pass The gate was changed to one at the end farthest from original gate It was supposed to be two flights - she ended up with 7 boarding passes in the end. Second really unpleasant flight with Air Canada in less than a year. Will avoid Air Canada from here on."

Cons: "Salty pretzels!"

Pros: "flight was on time"
Cons: "not even a little snack served with the drinks and the amount of legroom was minimal and I'm not tall"

Pros: "The crew actually enforced the zones when boarding, which often isn't the case and tends to slow things down."
Cons: "This connecting flight was worse, as we sat on the tarmac for well over an hour and were not provided with so much as a single beverage the entire time we were waiting or flying. Apart from the great in-flight entertainment system, the whole experience was brutal."

Cons: "Ticketed for Air Canada, but it was a code share flight with United Airlines. The check in at United took over 15 minutes because my reservation was not recognized by the United online system. Luckily a United agent was able to work through my paperwork and get me checked in, with luggage, via Ottawa to London, Heathrow. However, at the boarding gate for my flight to Ottawa, my boarding pass was deemed invalid and it took another 15 minutes to issue a new boarding pass - with seating at the back of the bus. Was a frustrating/annoying process. Luckily I encountered two capable United employees who worked to resolve the issues."

Pros: "The staff were efficient and friendly. The entertainment system is great."
Cons: "More room - but the flight was short and the price was right, so that's not a deal breaker."

Pros: "Gate assignment was only 44 minutes before take off and with the size of LHR got there after boarding had started. Confusion as right beside it was an AC direct flight to Toronto also boarding so lines were mixing. A hot meal provided which was good except for a stale roll and awful "salad". A hot wrap provided later in flight that was awful, should have used pizza pockets. Good crew and good flight. Always carry active noise cancelling ear buds or headphones."

Pros: "Lucky as this was not a full flight so I had the seat next to me empty and lots of legroom with a bulkhead seat. The attendants were very nice and the onboard entertainment had a good selection."
Cons: "The food is just not good. Air canada needs to get a new provider."

Pros: "Flight was comfortable despite long distance"
Cons: "Food service could have been better timed as we had breakfast around noon local time"

Pros: "I LOVED that they got me on the next flight without any issues. Wait time was just an hour longer"
Cons: "No ear buds for sale or offered. No charger plug ins in the seat"

Pros: "The flight attendant was super awesome. She was personable and had a great attitude. I didnt get her name, but she was by far the best! Blonde lady, smelled wonderful, very refreshing and funny conversation...(Ua1412 to LaGuardia) yeah yeah! Amazing!"
Cons: "I wanted the salami and cheese crackers but the flight wasn’t given any, so I chose the veggie smash/pita bread/quinoa/almond thing. Not too bad, but definitely no match for salami and cheese crackers. You know?"

Pros: "I want $254 visa gift card as a refund!!!!!"
Cons: "Please see above"

Pros: "Nothing"
Cons: "Our flight was delayed which caused us to miss our international connection. Flight attendants did not care, did not attempt to get us out faster, or put on a different flight. Asked for an announcement to be made on board or to be moved to seats closer to the front so we could get off the plane quicker, did not happen. Offboarded and sprinted across the airport for our international connection and was notified by gate attendents that the gate closed five minutes ago and that they could not let us on the plane. Meanwhile, the plane sat there for an additional 30 minutes while it fueled and waited for release from air traffic control. There were six travelers total stuck there in San Fran at that gate, all of us begging to be let on the plane to Beijing, the last one for over 24 hours. Zero compassion from staff at the the airline gate. They did not care about us and did not care about leaving their travelers stranded. Our total travel was Denver to Bangkok, 26 hours of travel including layovers in San Fran and Beijing. In San Fran (after missing the gate connection), United rerouted us through Haiwaii and the customer service agent that did this reroute did not finish the reroute to our final destination. We got to Haiwaii and were stranded again, at the United service desk for four hours having to once again provide documentation of our initial travel plans to Bangkok, having them build a new itinerary to our final destination. Overall, 20 additional travel hours have been added to our itinerary, almost double our initial travel time. We have had to call and cancel pre-arranged bookings in Thailand as we are now missing two full days off our trip. I am absolutely disappointed and heart broken as I write this still stuck in the Beijing airport waiting another six hours to connect to Bangkok. My fiancé and I were traveling to Thailand to get married and have received no compassion from anyone at this airline to try and get us there. I fly United for work quite frequently and have never experienced such horrendous service and lack of basic human compassion. I am flat out disgusted by United and will not be using them again, for personal travel or work related trips, because of this horrendous experience."

Pros: "The layover in Denver worked out perfectly - no long wait. The United entertainment availability. Friendliness of crew. On-time flight."
Cons: "The leg room. Small size of complimentary snacks. No screens for United entertainment so you had to use cell phone, but this eats battery and no power in our zone"

Cons: "2-1/2 hour delay due to poor maintenance"

Cons: "Seats in economy were cramped! Chair barely leaned back at all. Woke up with a sore neck. Cabin was freezing!"

Pros: "The flight attendant was trying to be accommodating. I and other passsengers bumped our heads when getting into seats. Can we say SMALL plane?"

Pros: "The crew"
Cons: "The seats r too small"

Cons: "No food no entertainment. It's a sad change from how United used to be"

Pros: "On-time departure and courteous crew. Smooth flying on this leg of our trip."
Cons: "I don't have any major complaints about this flight."

Pros: "Nothing"
Cons: "That my flight got delayed in Denver over an hour and I missed my flight from LA to BJX because of that. I was suppose to land in BJX At 6am on Friday April 28th for a family emergency and now my next flight isn't till 1pm! This is the worst flight experience I have ever had in my life. Never in my life will I ever fly with united again. My plans got ruined, I was forced to sleep on the cold dirty floor of LAX. This cost me a lot of time and money, and I am upset about it. I will tell all my peers about this horrible experience and encourage them to never fly with united ever again. I do expect some sort of compensation over this horrible experience."

Pros: "Phone charger at every seat"
Cons: "Earphones for movie did not work"

Cons: "Very late."

Cons: "Boarding by zones causes passengers to have to stand longer while waiting to board, inconveniences them by having passengers seated in window and middle seats often arrive after the passenger in the aisle seat, and slows down the entire process because passengers settling into the front part of the plane frequently board and stow luggage while those seated in the back queue up behind them. Compared to boarding by row, the entire process is now one lengthy mess."

Cons: "My flight was ten hours late and no accommodations were provided. 40% off tickets to hotels and no way to get to them."

Cons: "Very bumpy ride....but I realize that can't be helped"

Pros: "Amazing plane with great features! Incredible staff!"
Cons: "Bathrooms should be bigger"

Cons: "Delayed and got downgraded"

Pros: "nice flight attendancts"

Pros: "Good crew, smooth flying, on-time"
Cons: "Crowded"

Pros: "There was a lot of space and a quick departure."
Cons: "When we got to LA event though we were early we had to wait. I know its not the airlines fault but it sucked."

Pros: "The crew was very kind to everyone and it was a very pleasant flight!"

Pros: "Crew was great"
Cons: "Aircraft interior is dated."

Pros: "Hard working efficient crew. On time; a pleasant flight. Excellent flight attendant who covered all requests on her own."
Cons: "No problems"

Cons: "The plane temperature was ice cold and I was miserable the entire flight home"

Cons: "Nothing"

Pros: "The kindness of the staff."
Cons: "Having to go back to Denver because of a storm-in Omaha."

Pros: "I"
Cons: "I think United is improving constently"

Pros: "Friendly flight attendants, helpful staff at the ticket counter."
Cons: "Unable to check into both legs of my flight even though Air Canada used United for the first leg."

Cons: "Seats are not comfortable and no leg room"

Cons: "Crew was not particularly friendly. One man was brusque when I asked for water to fill my small bottle. Rare since most crew members I've experienced have been very pleasant. Snacks were pretty paltry. Ned to serve some biscotti."

Pros: "Everything went smoothly, and that's really all that matters. The crew was great."
Cons: "Don't know why we have to pay for entertainment. It used to be free."

Pros: "I liked the flight attendants that they were courteous and helpful"
Cons: "I am a fearful flyer and that is putting it mildly. I didn't like that the pilot didn't introduce himself and talk to us about the flight."

Pros: "I liked nothing"
Cons: "I didn't like everything. All my United flight were delayed, the international was cancelled after waiting for 7 hours of delays."

Pros: "Crew nice and friendly."
Cons: "Free in-flight entertainment should be offered on all flights of 2+ hours through the United app. Had a family with young kids next to me who would have benefited from it (I saw the father trying to connect to it through the app), and overall it would make the flight a much more pleasant experience. After boarding a full hour later than what was originally said, it would have been nice to kick back with a movie for the flight."

Pros: "I know it's some sort of miracle. But there was only 40 people on an airbus. We all had about 3 seats each and we made full beds for ourselves."

Cons: "Boarded and left late for many to miss connections. No real help to get to new connection both on plane and off."

Cons: "Delays! Numerous delays! No assistance to help with changing missed connections or getting a hotel while stuck in Chicago."

Cons: "Great employees!"

Pros: "A everything was fine other than..."

Cons: "Horrible flight delayed an hour and the. Waiting an hour for my bag to learn it didn't make flight even tho I was at ther airport 2 hours before flight left. They said couldn't deliver it until the next day so had to go back to the airport to get my bag! Horrible experience !"

Pros: "People at desk in Chicago very helpful"
Cons: "Terrible communication about flight info caused us to miss a flight. Limited desk hours made it a painful experience. I will never fly with Aer Lingus again!"

Cons: "On April 15 we flew from Sacramento to Basel, via Los Angeles and Munich. We did exactly what we were told re reserving seats. We were told to call 23 hrs. in advance to reserve seats. When we tried to follow directions, we were not able to check in. Without checking in, we could not reserve seats. After numerous phone calls, to various numbers, we were not able to check in or reserve seats. By continuing to ask questions, to try and understand, we were told we were "under airport control". This was an "at random" situation and online check in was not available. Only 5 minutes earlier, we were still being instructed to check in online! We had never heard of this. I contacted a neighbor, who flies often internationally and within the U.S. He said it had happened to him once. He agreed that driving to the airport in Sacramento was a wise decision. This is not what we wanted to be doing 1 day before departure. At Sacramento we found a kind gentleman who saw our dilemma and checked us in as a favor. We saw assigned seats. He suggested we request to improve our seats the following travel day. It was a very challenging morning. As I tried to improve our seating the following day I was told, by airport staff, that this happened because we booked through Kayak? Rather with an attitude that we should have booked differently. This was a vacation we had looked forward to for years. I worked hard at not letting this difficult start damage my trip. Upon arrival in Amsterdam, I tried to learn more, to prevent a similar situation on the way home."

Pros: "Love the free tv/movies with the United App. That was great!"

Pros: "I liked how the flight attendants treat people in this flight. Thank you all."
Cons: "N/A"

Pros: "As above"
Cons: "As above"

Pros: "Good flight attendants"
Cons: "Small seats"

Cons: "Delayed 3 times. United is known for delays, everyone jokes about United delays!"
