Cons: "Boarding"
Pros: "Nothing"
Cons: "Poor customer service, was booked off twice without being informed."
Cons: "Flight late more than 3-4 hours on Frankfurt. So upset. I will never and ever try with Frankfurt again. I bought shortest way ticket to pay more money but unfortunately flight late about 3-4 hours. Money trap. I would love to have another free flight or I will post the tickets on facebook, Twitter and etc... To make a terrible flight reputation."

Pros: "Everything exceeded expectations. Lots of food, space, drinks, and excellent flight crew. Excellent video selection."
Pros: "The crew here was Much, much friendlier! They were smiling, joking, and happy. The stewardess even directed me to a free isle seat so I wouldn't have to sit in the middle where it was a bit more cramped. I wish my first experience with Lufthansa; they could have had a loyal customer since I will ve flying to Bulgaria 2 times a year in the next 6 years."

No babes the entire time I was in Germany. Arrived in Mumbai after paying the $350 US change fee and no bags. Bags finally arrived on Monday at 9AM Without clothes, toiletries and medications for 6 nights. Now I am delayed and will probably have to pay rebuke and fare change to extend my stay here."

Cons: "Boarding process: just a lot of confusion. Inflight crew service poor: the was no time to have any brain reaction when they would pass by with coffee or anything...and when I asked for coffee the answer for a gentlemen of the crew was: coffee already passed by. Really!!?? Make sure that +$1200 are spent well. Rude or inattentive crew members shouldn’t be on flights that are that long...I had to nsist to have a miserable cup of coffee. Movie selection was poor. USB port didn’t work. Shame on you!"

I found out in the plane after i got to my middle seat that they gave a good front seat close to the path to somebody who was stand by..... They also stated that they can not check my nags to Sofia since they DO NOT FLY TO SOFIA..."

Pros: "The crew was very polite!"

Pros: "The crew was friendly and provided constant updates while the flight was delayed multiple times."
Cons: "It is not a good idea to serve dinner at 1am in the evening when people are falling asleep. It would have been a better idea to serve lunch vs dinner"

Pros: "Nice crew"
Cons: "Lack of leg room!!! After my bicycle box was inspected they failed to secure my bike the way I had it in the box. Bike was flipping around in box. Bent rear brake calipers. Bent brake hoods. Rear skewers were uncoupled. No way to treat a $10,000 bike! Very upset!"
Cons: "seats were old and uncofmortable. i asked for coffee which they totally forgot to bring me and the crew was just generally mean and very dismissive. no food at all - could have served a breakfast sandwich or something no entertainment or charging docks. ."
Pros: "Disappointed overall. United Airlines took over here and you could immediately tell the difference."
Cons: "Seats were uncomfortable, no food only snack which is typically crushed pretzels. I typically never fly United because of their service, food etc very poor"
Pros: "I've flown on many different airlines since I was 10 years old and hands down this Lufthansa flight was the best and smoothest flight I have ever experienced. First of all, the plane was very comfortable and had good leg room. The flight staff were all extremely courteous and attentive. There was one point where I was reading in the dark and the crew member asked if I wanted the light turned on to read! Normally I don't sleep on flights, and the same crew member asked if I wanted ice cream since I don't feel like sleeping. The crew seemed to have this magic ability to make the flight more comfortable without the passenger having to even think about it, or try to ask for extra service. All of the crew were just very outstanding and organized throughout the entire flight, they were all generally very helpful and kind. By the time I got off the 14 hour flight, I didn't feel even the slightest bit tired or anxious, I was able to spend time with my friends in Budapest upon landing and stay out till 2 am without having to sleep or rest because the flight was so good."
Cons: "Rude (American) passengers not keeping the "curtain down", when it was time to rest, and being very chatty. Also baby crying, but this is inevitable, it happened to all of us, when we had small babies."
Pros: "Great crew members, service, and flight."
Cons: "Seat (43A) in economy class in Airbus 330 is not great for oversea flight unlike I flew in LH 747-400 in the past, it does not fit 6+ ft tall people. I could not stretch my legs at all. My knee keep hitting next seat at front of me. Hello Lufthansa, are you listening?"
Pros: "The food was very good. The service, the preciseness."
Cons: "I didn't like the entertainment, there should me more options for movies in English and Arabic."
Cons: "They cancelled the flight and did not help at all for rescheduling."

Cons: "Seat comfort was meh."
Pros: "The plane was clean, fresh looking. Flight attendants were helpful and courteous."
Cons: "Check in at Vienna airport was awful! Chaotic, no help! Kiosk software was horrible. Touch screens didn't work. No back button so, if you made a mistake you had to start from the beginning. Passport reader was not working properly. Machines were slow and delayed in responding. Not enough staff available for assistance. Arrival at LAX was even worse. Plane had to taxi for 30 minutes all about the airport runways. Finally got to a gate -almost on the beach! Then had to bus everyone to main terminal. Slow in getting bags to the passenger pickup. It took us 2 hours post touchdown to get out of the airport! Almost missed the airport shuttle,"

Cons: "No entertainment available not even to pay for. Wifi is overpriced"

Pros: "The service was good, everyone from the staff extremely friendly and overall the flight was very quick."
Cons: "It took us 2 tries to get there due to weather and they had us waiting in the airport for 12 hours in the middle of the night. We first flew to Lviv and then they turned the plane around and came back as we were landing. I appreciate that they did this for safety reasons. When we got back however at 2:30am, they did not provide us with a hotel and just gave us blankets and pillows to sleep in the airport. They also offered us only a piece of bread with ham and cheese and a coffee for the next 12 hours until the new flight left. Not a pleasant experience."

Pros: "Nothing extraordinary, just solid positive experience from checking in on my phone thtough disembarking"
Cons: "I like the convenience of the built-in multifunctional screens (like on Alaska flights) that AA are lacking"
Pros: "We didn’t crash and die. That’s the only positive."
Cons: "Before we boarded I listened to a couple described how they always went ahead in line at boarding because no one ever stopped them. They described how they waited until group 3 was called and then went right through. While we were waiting, we watched them do it again. If you need to cram people into tiny spaces to be profitable, then you cannot allow them to make it worse by putting back their seats. I spent 90 minutes with a seat back jammed into my chest. We were ignored when handing out snacks, probably because we were invisible behind the seats pushed in our faces. It was one of the most miserable flights I’ve experienced."
Cons: "You were out of earphones"
Pros: "We were allowed to board early with my father, who is disabled."
Cons: "Denver airport was a nightmare with my disabled father. We were given a “wheelchair” but no escort through a nightmarish security scene. Airport is terribly designed, lacking clear signage and navigation. TSA was a disaster and no one seemed remotely concerned about my father’s comfort or needs."
Cons: "I never made it... I had a trip interruption and got stuck in Chicago and would of had to wait another full 24hrs to take the flight to Denver. tired and nauseated after being all day at the airport that at midnight, i knew that I couldn't hold off till the next evening, took the next flight back."
Pros: "Flight attendants were very good."
Cons: "Pilots need to do a better job of communicating delays. Especially the ones piloting this particular flight."
Cons: "Checked baggage untimely, causing me to miss the train"
Cons: "We are delayed 7.5 hours dues to mechanical issues with our plane and told we would have to wait or book another flight the following day. American Airlines sucks!!!!"
Cons: "Less boarding groups"
Pros: "Good, cheap flight that gets the job done. No issues boarding, seats were fine. Cannot comment on most things as I fell asleep almost immediately."
Cons: "Would've been nice to have had an eye mask / blankets on a red eye flight..."
Pros: "Not much"
Cons: "Seats that worked"
Cons: "I have changed flights. Been delayed 5 times now. And still haven’t left the USA."
Pros: "Boarding was smooth."
Cons: "American needs to recognize that people in Miami are savage animals and don't have manners, which is relevant to getting off the plane. They come running up from the back and clog the aisles instead of letting people off row by row like the rest of the country does."
Pros: "The crew was very friendly and accomodating."
Pros: "There was nothing to like about the way this sudden last minute cancellation was handled."
Cons: "I expected at least an offer of some kind of compensation for the inconvenience. it didn’t and hasn’t happened thus far."
Cons: "The crew was a little late"
Pros: "Crew was nice."
Cons: "Plane was very old (from the 90s?), cabin kept freezing all night. Now my husband's luggage has been lost and we are getting conflicting information on how to retrieve it."
Cons: "90 mins late leaving LA caused us to miss connection from Brisbane to Darwin now delayed additional 12 hrs. LA Qantas rep lied and said every 2 hrs there were flights from Brisbane to Darwin and not to worry. Truth is only one per day."
Pros: "The crew on both legs were attentive, especially in helping people with connections deplane in Dallas. Boarding was easy. Checking one suitcase for free was good."
Cons: "the first leg of the flight was delayed. The information about when it would leave kept changing at the gate. I would have appreciated some extra food due to the delay... I was unable to get food in Dallas, which my scheduled layover time would have allowed."
Pros: "Good movie selection, there’s new titles available to see and it’s perfect for flight time from Denver to Dallas"
Pros: "Crew was nice and friendly. Pilots flew great. We arrived a few mins early as well."
Cons: "On the way to Denver from Miami we were on a nice new AA plane with TV entertainment, movies, power, and comfortable seats. On the way from Denver to Miami we were on an old plane with no entertainment and old uncomfortable seats. If this is going to be the case, charge me less up front as well. My daughter had a terrible time for a 4 hour flight."
Pros: "fairly comfortable, crew was helpful"
Cons: "Having to use my phone for entertainment, with no place to plug it in"
Pros: "Had the fortune to sit with a passenger that had a service dog"
Cons: "Takeoff was delayed Two hours and 17 minutes with NO explanation."
Pros: "Comfortable seats, good legroom."
Cons: "Not enough coffee for breakfast."
Pros: "Boarding moved along well, even though there wasn’t special boarding for families with young children. The plane was really comfortable (new 2x2) and the staff was really friendly."
Pros: "Food and entertainment were great"
Pros: "Loved entertainment system need bring wireless headset however they will handout some later in flight."
Cons: "Seats were leather didn't let back air out."
Pros: "The crew was awesome."
Cons: "You guys lost our luggage!"
Pros: "The America flights were all ON TIME."

Pros: "All good, except poor prep on food"
Cons: "As above"
Pros: "Good connection"
Pros: "I like that American offers free movies thru their app but there was a glitch and I couldn't get it to work!"
Cons: "Couldn't get the entertainment app to work"
Cons: "The flight was delayed 9 hours for mechanical issues and they were not able to do anything. Since booking with Kayak neither Alaska airlines or American Airlines would help in getting us an earlier flight and both airlines said they couldn't help after repeated calls. Won't be booking any American Airlines flights throug Kayak again."
Pros: "Quick and easy boarding"
Cons: "Uncomfortable seats"
Pros: "Flight landed 40 minutes early"
Cons: "Due to early landing, no gate available. We literally rode all over the tarmac making room for other planes to maneuver around...and then did not get to a gate until 15 minutes past ORIGINAL arrival time. Also, I booked a premium seat, but there was no more leg room than any other seat. No meal/snack for purchase was even offered."
Pros: "Boarding and baggage."
Cons: "This was a long non-stop flight from Miami to Denver. Over 4 hours. So I took the plunge and bought first class. I always fly first class on any flight over 2 hours. However, I was disappointed. The food was so-so and insufficient. The drinks were also not enough. The video displays were small and poorly located for the movie. The seats seemed uncomfortable. All and all I have come to expect a better experience from American Airlines in First Class. The ticket was expensive."
Pros: "Getting through security was a lot better than I thought. Also, I had plenty of room and the overall ride was smooth."
Cons: "I just wish that there was a little more room and easier ways to earn miles and entry into the lounge."
Pros: "No complaints. Keep up the good work, American!"
Cons: "I don't like the fact that food has to be purchased. I liked it much better when the food was included in the price, as it still lives in the major international overseas airlines."
Pros: "The Denver airport is beautiful"
Cons: "I will never fly AA again - see below"
Cons: "I had to leaves Denver early due to my granddaughter needing help. To sees switch returns my ticket it would cost me me $200.00 but it could get a retire ticket for that day for $40.00. Why couldn't that dollar amount come of my ticket . That was just crazy"
Cons: "I had a severe back injury in Denver and they were unable to move my flight up a day to get home and see a doctor. A good friend had to buy me a new flight with his airline miles so that I could get home to relive my pain. I'll never fly American again because of this complete lack of compassion and care for their customer."
Pros: "On time. Good crew and nicer flight."
Cons: "Actually no complaints."
Cons: "Food service was pay only on a 3.5 hour flight. This meant there was a good cart blocking the aisle THE ENTIRE FLIGHT! Nobody could get by to use the bathroom or to walk around. There was almost always two people in each direction blocked by the cart. From what I could observe, the cart wasn’t even stocked with the items people were ordering, as a flight attendant was CONSTANTLY running back and forth to the galley to get items that weren’t on the cart! The setup of this food service was HORRIFIC even for me who didn’t order anything. They never even were able to take orders from everyone- never even asked if I wanted anything. I don’t think I will fly British Airways again."
Pros: "Crew was friendly, food was good"
Cons: "Entertainment was broken in one of our seats, the seats were not comfortable"
Pros: "The seats were comfortable"
Cons: "Everything was ok"
Cons: "Took a very long time to empty the plane via staircases. For a 747, I expected a jetway at Heathrow."
Pros: "I really like this airline"
Cons: "The crew were all very nice"
Cons: "I am a 5’8 woman- pretty slim. I had a window seat in the main cabin. I barely fit! But the guy in the isle was bigger and had to wedge himself into his seat. As a result, I couldn’t leave my seat for the entire 9 hour flight. Come on BA! Have some compassion! These long flights need bigger seats."
Pros: "My flight was over four hours delayed and I appreciated that when I got to the airport and found that out, I didn’t have to ask for anything but was immediately greeted with a food voucher. I lost an entire days worth of vacation in Germany, so well I do feel the British Airways should have done better and should’ve compensated me better, the fact that they immediately took steps to make the situation better was greatly appreciated. That level of customer service was beyond any I’ve received with an American-based airline. Also, the crew on the plane was fantastic and a great choice of movies. I flew American on the way home and was shocked at the lack of customer service and rudeness, I will happily fly British Airways again and again."
Cons: "A plane that was over four hours late costing me an entire day in Germany."
Pros: "The departures and arrivals were on time."
Pros: "Easy boarding, on-time departure, clean aircraft, friendly crew, decent food, free drinks."
Pros: "Despite having a delay in Denver, we were able to arrive on time. The crew was very friendly in greeting us as we boarded the plane"
Cons: "The boarding process was hampered by too many people putting too much carry on luggage in the overhead bins. Many put things in the overhead bins that could have been put under the seat. It didn’t seem like the crew was paying too much attention to this. In general the crew was pleasant, but there didn’t appear to be much sincerity in the pleasantries."
Pros: "The crew was very friendly. Lots of movie options. I got a voucher due to the delay."
Cons: "The delay was a bit of a bummer and it would have been nice to be compensated with more than a voucher that couldn't be used in LHR because it was in USD. I also would have liked to been told they were still planning on serving dinner despite the midnight departure; I fell asleep because they turned off the cabin lights and I assumed the meals had shifted, but instead I missed out of my dinner. Lastly, I am quite petite and still struggled with legroom."
Pros: "Crew was friendly and helpful, food was ok."
Cons: "The flight was delayed by roughly 5 hours, causing us to miss our connection and have to wait for the next flight. We missed a half day in Rome and instead spent over 8 hours waiting in airports. The seats were also terribly worn and uncomfortable."
Pros: "Orderly boarding and disembarkation."
Cons: "This airline is one of the worst in Europe, for the simple reason of putting short-term profits ahead of decent treatment of the customer. My flight across the Atlantic was 4 hours late, and BA refused to put me on the next available to Prague, even though the lateness forced me to miss the BA flight I have been booked on. Their reason referred to a technicality in the booking procedure, but actually BA has put in place "policies" aimed at their financial advantage, over and above reasonable treatment of the customer. BA's refusal to rebook me cost me a lot of inconvenience (3 hours on the phone, for one thing) plus about $150 (I am taking another route to Prague); BA was then able to sell both my original seat and an extra seat on the next flight from Heathrow to Prague. I will never fly BA again in my life if I can help it."
Pros: "Food and hospitality and staff"
Cons: "We were late 20 minutes and sat in tarmac another 15 minutes. Didn´t allow us enough time to get train, take bus, we had over 500 people lined up for bus, get through TSA, they pulled my suitcase for inspection, but didn´t look at it for 15 minutes until i called a supervisor as my connecting flight was leaving, and in fact, it had left as TSA does this purposefully and maliciously as it apparently happens all the time per ÇBritish Airways who had to reticket us. We had to return to A section another 20 minutes to be reticketed and luckily got on another flight to <madrid. Terrible experience with TSA. Very rude, angry, abusive staff."
Cons: "Our flight from Denver to London was canceled at the last minute last night. The information from your email and the number given from you notifying me of the cancellation only gave British Airway to contact for redress. It took over an hour on the phone to get another flight which was 2 days later with now 2 days less of our vacation. Not to mention the loss of 2 hotel room payments. Kayak was of no help in this matter. Plus our flight reservation prohibited us from getting our flight on another flight the next day. If I had known that I never would have used Kayak. I am extremely unhappy with how this was handled. I expect to be reimbursed for our lost Hotel room costs and the costs associated with lost tours from you. Please contact me with how you will go about doing this."

Cons: "Food was inedible so I left it. The sound on the movies was tinny making hearing difficult."
Pros: "Excellent food and service."
Pros: "The food was good and there was a great movie selection."
Cons: "I felt like a sardine. The seats are very tiny and there are so many of them."
Pros: "Treated coach like first class."
Cons: "Nothing"
Pros: "Boarding went fast."
Cons: "Too tight, not possible to sleep a little bit."
Pros: "Crew were exceptional in service friendliness and attentiveness."
Pros: "Clean plane"
Pros: "The efficiency of every sing step from booking to boarding"
Cons: "The type of the people flew with me -loud and misbehaving. Crew couldn't do anything."
Pros: "Entertainment, blanket"
Cons: "Not enough leg room, chocolate dessert"
Pros: "Seats were comfortable and staff was very attentive as well as respectful of us when I was sleeping"
Cons: "There was condensation leaking from the ceiling of the cabin. A crew member said this was normal, would have been nice to know this ahead of time to reassure me that for a first-time overseas flier that this is normal."
Pros: "food was good"
Cons: "IFE was not good the equipment is very old and selection is limited"
Pros: "Service, food, safety video"
Cons: "Delayed flight"
Pros: "Fligth attendants of British, Iberia provided excellent and friendly service. Some of London British Airways desk and gates officcers, gave me really poor service."
Cons: "My flight to London was pretty good,. Service was excellent.. But not my transfer to Madrid , I lost my conecttion. On London airport, I was sent back for the gate because I showed up early and they ask me to take care of the screen and wait for the gate #, when they showed the # , I went to the gate and was told my flight had left an hour ago and sent me back walking . I was wearing an orthopedic shoe, due to a toe fracture and i had to walk again all this long distance back to the terminal.!! British airway gave another flight and had to pay $279 dlls for a ticket to Madrid.2 hrs later. My flight was by Iberia and the service. was excelent. I wonder if the insurance , I bought initially will cover something of the $ 279 dlls ticket ? Fligth back to EUA was by AA and service was excellent"
Pros: "Crew was very nice."
Cons: "There are no air vents on these planes! 4 of the 4 international flights of 10+ hours each did not have individual air vents. The heat was unbearable. We were sweating the entire time. There are individual computers in each row taking up some of the seat B (middle seat) legroom. These blow hot air and heat up the plane even more. I have never been on a flight where there weren't vents and it is the #1 reason why I won't be flying British Airways again. The TV screens are also outdated. The selection is alright but the screens are blurry and have a grid burned in on them."
Pros: "Very courteous attendants"
Cons: "All good"
Pros: "Very little."
Cons: "Flight was delayed. The seats are uncomfortable and too small for even normal size male. Food was disgusting. Staff were very nice and helpful if asked. I think all the space and comfort were in buisiness and first class. Economy class is still paying for a ticket, make up most of the passengers and deserves better. Getting into a seat was like getting into a straight jacket."
Cons: "food was not good."
Pros: "Absolutely nothing"
Cons: "Flight was delayed by 2 hours. Then they bumped us out of the seats we had reserved. Made it just in time for our connection. Then they bumped us from that flight. Others were given generous compensation for that bump. However we were given nothing. At least they us we could rest in the BA lounge because I am elderly and disabled and we would have a 9 hour wait. Got to the lounge and we were not listed in the system. So we were denied entrance. We will have have spent 2 nights on a plane and 36 hours instead of one night and 16 hours. Rotten way to depend your 50th anniversary."
Pros: "not much"
Cons: "5.5 hours delay"
Pros: "Just so comfortable and friendly. I'll fly them again next time!"
Cons: "Nothing."
Pros: "legroom"
Cons: "Boarding started 10-15 minutes before the announced boarding time and I did not hear an announcement for that. Seats are very uncomfortable, they have no lumbar support and my lower back still hurts from the three hours on the plane. 2 toilets for all economy class passengers are not enough - there was a line most of the time. Water for purchase???Are you kidding me? That was the worst surprise! What a shame, British Airways! Now you are one of the inhumane airlines! I will tell THE WORLD about that ridiculous fact! And not even extra small packages of snacks?! Now my favorite airline becomes Delta. There was no entertainment of any kind. There were no air vents above our seats (row 20 in that Airbus) and it got really hot before we were airborne."
Pros: "Nothing"
Cons: "Old plane, flight attendants boardering in rude, very poor food (!), de-plane via steps to the tarmac and at least 7 coaches at Heathrow (an aged 747, so it took nearly an hour!)"
Pros: "Everyone was awesome"
Cons: "The staff was awesome"
Pros: "The food was elevated and we were fed twice on our 9 hour flight! The beverage service was also provided often with a good assortment. I loved that there were new release movies available for free. The staff was friendly and available. If I were to do another long flight like that, I would seek out British Airways."
Cons: "Nothing."
Pros: "No turbulence!!!"
Pros: "For economy class it was good seats (bulkhead), the crew were nice, and the food was good."
Cons: "The tiny screens for movies were awful. Worst of all, the horribly loud voices that nearly break eardrums when the crew comes on during the flight was both painful and annoying."
Pros: "The flight was not very full, so we could spread out. Normally I really like British Airways, but the lack of AC was difficult."
Cons: "The air conditioning did not work and it was very warm, 77 degrees at least, the whole flight. It made it very uncomfortable. They said something was broken."
Pros: "Easy and quick boarding. Dinner tasty, but it is hard to cut a fillet steak without hitting the next passenger in the elbow"
Cons: "Only one check-in agent running all desks including bag drop - long wait. 19 year-old 747 had narrow seats in premium economy, uncomfortable and too much body contact with adjacent passengers. Outbound to SFO in an Airbus 380 had sparkling wine pre-take off, hot towels twice, this DEN-LHR flight only had juice or water on offer (crew said "don't serve that on this route") no hot towels, crew's objective seemed to be get around cabin in one go and leave Pax to it Breakfast was abysmal, soft-pretzel roll, no juice or water served, just indifferent coffee"
Pros: "We didn't crash."
Cons: "Seat was exactly the same as coach. My vegan meal consisted of 2 tiny plates of fruit and a soggy, egg-free omelet with unflavored tofu and no salt. Disgusting. Staff was snobbish and full of it. No on-board entertainment, no wifi, no reading material except the magazine. Oh they did try to sell me duty free. AVOID."
Pros: "Usual fantastic standard of service"
Cons: "Shabby baggage reclaim service at LHR with staff ignoring priority baggage"
Pros: "It all went smoothly and was on time"
Pros: "ALL the cabin crew were excellent! Polite and helpful and cared for the comfort of all their passengers."

The flight attendants were knowledgeable and informative. Our incoming flight was delayed due to snow and ice. Once we were aboard the flight from Denver to Detroit, the pilot informed us that we needed to go to de-icing prior to lift off. He led us to believe that it would only delay our trip by 10-15 minutes. We sat on tarmac for one hour prior to lift off. I definitely appreciate the safety process of de-icing but I wish the pilot had given a more realistic estimate of time of departure.

Cons: "I have no complain it was good for the most part for, more food lol"
Pros: "Good seat in preferred section (paid for at reservation)"
Cons: "There were delays (3 times)"
Pros: "Good legroom,"
Cons: "Older aircraft, tray tables not level, rear washrooms no water, delayed departure"
Cons: "Food had little taste. Movies were not that current and selection was sparse"
Pros: "Crew was great!"
Pros: "No leg room"
Pros: "Cabin crew were terrific!"
Cons: "The unfortunate delay of our flight. And the entertainment systems seems to be getting old. What I mean is that it is by todays standard very very slow to switch between menus etc. And in some cases did not display all the menu content."
Pros: "very nice crew"
Cons: "plane was too small and there was 1.5 hour delay departing"
Cons: "Ended up missing this connecting flight to Calgary . Our plane left 45 minutes late from Phoenix because of a gas spill so when we got to Vancouver from Phoenix, we had to go through customs which took extra time. When we first landed in Vancouver and before we even got off the plane, we had 5 minutes to board onto our next flight which obviously was not going to happen. We rushed through customs and still might have been able to board our flight at the last possible minute except the staff at the airport led us to somehow get out of the secure area and have to go through security again before going to our gate. That took so much extra time. This never should have happened. When you get off the plane and have a connecting flight, there is always a way to get to the gate to board without having to go through security again. When we finally made it to our gate for our connecting flight, our plane had left and we were told to go to the air canada service desk. There was about 10 to 15 of us that had missed our connecting flight because of this so the 2 staff at the desk were trying to help us all but had to wait for their manager to come and confirm they could give us another flight which took quite a bit longer than I thought. We ended up getting booked on standby on a flight straight from Vancouver to Saskatoon in 2 hours which was our final destination, but never was told that because of all this headache, we should have grabbed our luggage. We thought our luggage was going to go on without us on the flight we missed but apparently if you do not get on your flight they don’t send your bags which makes sense. We also had thought for a second that maybe our luggage didn’t go on the flight from Vancouver to Calgary but if it didn’t then someone would most likely put it on the flight to Saskatoon. We should have asked about it but they should also have mentioned it when we were in a panic. And I understand you can’t put extra people on a flight that is booked, but what if the plane we were on standby for was full and we had to wait even longer .. could have taken us a day to get home when this wasn’t our fault we missed our flight, but was air Canada’s."
Pros: "Not much. Crew was good but that is about it."
Cons: "Tight spaces packed in like sardines. FAA seriously needs to look at how these airlines pack us into these seats. Can barely sit in the set, no room to stretch legs, tray table hits my stomach, and I don't even have a big belly. When the guy in front reclines, cannot even get out of my seat. Chaotic boarding process without any order or instructions or announcements, poor food and entertainment."
Pros: "The full experience"
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: "I can't take the flight and I can't get my money back. It is horrible"
Pros: "The flight crew were helpful and friendly"
Cons: "I was forced to miss my second flight because the first airplane malfunctioned"
Pros: "This was a long flight so we opted for premium economy, which upgrade was very reasonably priced. Almost everything about the flight was wonderful; friendly, efficient crew, comfortable seat and temperature, tasty food and generous drinks and on-time departure and arrival."
Cons: "The entertainment app which we downloaded to our iPads prior to the flight, is a bit flaky in that it would get in a loop of advertising and made watching a movie frustrating"
Cons: "Rather than notify the passengers that our flight would be delayed prior to our arrival at the airport, we waited at the gate for several hours."
Cons: "Our direct flight to Montreal was canceled due to mechanical issues. The rebooking process was discombobulating and we ended up arriving at our destination after the rerouting that was stressful and ensured that we lost a whole day of our vacation time. Our flight back the entertainment system in our seats did not function."
Pros: "put us up in decent hotels gave food vouchers the crew didn't do anything to make it horrible Large selection of movies/tv on board comfiest seats out of all the major airlines I've flown"
Cons: "The flight kept getting delayed bc of mechanical problems, and then eventually cancelled. They rebooked everyone on new flights, but it took an extra stop in Toronto before getting us to Montreal. Once it was rebooked for the morning, it took off a little late. Plus the pretzels they gave us were stale. This was the first of two flights I took this trip that had mechanical issues, so they obviously need to fix their planes better or get new ones, because two Air Canada flights in one day that have mechanical problems leaves me worried that the planes aren't in optimal condition. It took me over 24 hours to get from Tucson, AZ to Montreal, Canada when normal travel takes less than 8 hours including layovers."
Pros: "I had room!"
Pros: "I had an aisle seat"
Cons: "The plane sat on the runway in Denver for over an hour because they couldn't figure out their furling situation. Many people nearly missed connections because of this. The crew never let us get up to go to the bathroom on an international flight because of some small turbulence."
Pros: "Nothing! Unpleasant unhelpful crew at gate, no better onboard, absolutely moist cramped seating ever! Disorganized and late- boarding, departing, waited to disembark at arrival, 25 min before first bag off baggage......dreadful no one cares"
Cons: "Thank you for choosing Air Canada- smiles and goodbyes- where's all that Before you leave? They treat you like problem cattle to be dealt with, you're anonymous and valueless until you leave then they look at you and thank you?! Missing sincerity And service!"
Pros: "Onboard attendants were pleasant"
Cons: "No apology for lateness, flight boarded late, took off 40 min late, arrived 35 minutes late but we sat at gate waiting for someone to open it ?!, then another 15 min before bags started to unload Ridiculous but indicative of airlines You are not their valued guest or even their customer, you are a problem that needs to be solved and are consequently met with preloaded annoyance and a readiness to dismiss, placate at the best of times but definitely not please, impress, sympathize or satisfy. There is no evidence that it's even in their lexicon- not a part of their recruitment or selection process or training, ever! They're main focus and only positivity is saved for themselves. There may be a long line of concerned and anxious travelers but their priority is getting coffees for the battle ahead! They break their focused indifference only for each other and enthusiastically leave their post to satisfy each other's needs and attention. This has got to change! Why do we put up with such awful service for which we are the paying customer? Why are we, their customers, not valued? This airline makes record profits, provides less, charges for everything and increasingly delivers bad service, sometimes offensively bad! It doesn't cost more to hire a customer centric pleasant person, or incorporate guest experience into training or at the very least be friendly and smile! What if an airline just did that?! They'd differentiate themselves and develop a positive customer centered culture. Don't we deserve that, at the very least?!"
Cons: "Crew wasn't helpful and attentive, boarding staff in Toronto were blatantly rude to me, I watched as my luggage got handled aggressively, the plane was dirty with old food crumbs and such, my flight to Windsor got cancelled and accomadations were not met sufficiently."
Pros: "Staff were courteous. No problem there."
Cons: "The plane was old and there was little leg room. Should retire it."
Pros: "Flight was on time. Personal entertainment is very good and crew was great."
Cons: "Boarding is always a bit chaotic with the carry on bags. I am tall, so economy seats are always uncomfortable."
Pros: "The flight was perfect. Stress free. I will definitely get it again."
Pros: "Low price with big value. The food was great and service felt like first class. The staff was friendly, courteous, professional and accommodating! Definitely recommend and will fly with Air Canada again!"
Cons: "The long layover, 14 hours"
Pros: "Comfortable aircraft - 767"
Cons: "What food? Salt pretzels are not even truly safely edible!"
Pros: "On time Courteous Good service Decent business class seats"
Cons: "Bit of vibration on the front wheels on take off rough landing, similar vibrations Mediocre lounge (by United in Las Vegas airport)"
Pros: "I like that Air Canada provides entertainment and its flight attendants are really good."
Cons: "I rarely fly these partner airlines without experiencing major delays, and the delays are always announced after I have cleared security, forcing me to spend hours at the airport. The claims of "weather" are specious: they don't fly enough planes and they don't properly maintain the planes they do fly."
Pros: "Online booking,boardong pass, alerts"
Pros: "Crew service in the plane was very nice, plane was cold and clean as it should,"
Cons: "Lost a flight because they closed the door 20 min before departure, no calls where made to passengers ... I was delayed by airport security and by the time I made it to the gate it was already dispatched, flight closed doors 10 min after it was scheduled to board, very efficient boarding crew that left 6 passengers on the ground !! Since it was a short flight between Toronto and Montreal they gabe me a seat in the next flight which had a delay in boarding (30 min) and then delayed departure too another 30 min ... All in all i spent almost 5 hours in the airport for a 1h flight"
Pros: "Crew was nice"
Cons: "Couldn't use in flight entertainment, only half a soda was given"
Pros: "Nothing"
Cons: "Customer service flight rebooking"
Pros: "Food on international flight was horrible, they lost my luggage, last flight was an hour late with no explanation. Still don't have my luggage."
Cons: "No monitoring of travel route"
Pros: "On time boarding and on time landing"
Cons: "Shaking moves just before landing, very scary"
Cons: "Flight was delayed nearly two hours. Gate signs were never updated. 7 gate attendants spent 1.5 hrs standing at the gate talking laughing and joking amoungst themselves. They appeared annoyed when anyone asked for an update. They finally announced they were waiting for a wheelchair to unload a passenger from the previous flight. They announced they were ready to board zone 1 and 2 and then did nothing for another 25 minutes. Funny when we finally boarded nobody ever saw a wheelchair go on or off the plane. Understand that flights are delayed but no updates or explanations and a gate crew that seemed annoyed that the passengers were disrupting their social time was unacceptable."
Pros: "Nothing!"
Cons: "Nothing, everything was bad. Flight were late and service was really bad. I will never fly Air Canada again!"
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: "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: "Better plane than previous"
Cons: "Had to be rerouted to Calgary because I missed my connection"
Pros: "Nothing"
Cons: "Poor food choice and quality , comfort of seats"
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."
