Airline reviews

Pros: "Food fine. Entertainment choices fine. More leg room than American."
Cons: "Departed over an hour late. Preferential treatment given to a family member of flight crew. Also, kind of stingy with water."

Pros: "Yes but when you offer a blanket deliver a blanket :)"
Cons: "When you offer a blanket or to heat up the food follow through :)"

Pros: "Nothing"
Cons: "Direct"

Cons: "I missed my connection because of the late arrival"

Pros: "Cabin crew."
Cons: "Security at Heathrow."

Pros: "I liked that the center seat was empty."
Cons: "My seat back didn’t recline as much as the seat in front of me or the seats beside me."

Cons: "I was seated at the emergency row. The staff has a policy of collecting the pillows and blankets during take-off from these seats. But they never gave them back to us afterward. Later when I wanted to go to sleep, they could not located these items."

Pros: "The best flight that I have had in my life. Never been a very good traveler going on long distances. Peter came it was great. The number of times there were these snacks and meals offered along with coming up and down the isles with extra cups of juice was really nice. I was fortunate enough To have purchased and reserved in advance and emergency exit I’ll seat which gave me the room that I needed because of my length."

Pros: "For the most part the crew was attentive, kind, sweet, and overall wonderful. Food was good. Great options for vegetarians. Loved the ice cream as snack:). Clean sealed blankets. Loved the movie and tv options. For the most part very happy with service, cleanliness, pilot keeping us informed of delays or anything going on with the flight. Leg space on coach was difficult for tall people and my son's tray table tilted to where he had to put blankets underneath to keep it straight and avoid further spillage."
Cons: "Again the crew has to be informed regarding disabilities. This time an attendant did not allow me to leave my one window closed and said it was due to security and asked to wrap a blanket around my head. Really??? Light streaming into my window was blinding, no time to adjust to the surroundings, light just came through everywhere. Headache ensued even shielding my eyes with the blanket. At least my family helped guide me out. Though head injury is not a visible condition it is still a disability which requires consideration and must not be treated lightly. I perform due diligence to address my disability without extra assistance outside of my family....I only asked for my one window to remain closed. There is still light around enough for people to see more than adequately. This incident is the reason for the 3 stars...because of one crew member...instead of the deserved 5 for everyone else."

Pros: "Entertainment and food"
Cons: "Boarding was slow, and disorganized."

Cons: "The food service had problems. When they got to our row they didn't have any more of our dinners left and without asking I was given a meal from first class with an entree I did not care for. My wife seated next to me gave me half of her entree. Then the snack towards the end of the flight I was given a burrito type thing without asking what flavor I wanted. All in all the food was poor and the attention to the passenger was poor also."

Pros: "Texting about lost bag, fast information"
Cons: "There not enough time for right connections if always delayed, bags are not at the destinatiion, no drinking water without ovepriced purchase on the plane from London to Prague,"

Pros: "Good leg room"
Cons: "Movie system frequently had to be rebooted."

Pros: "Comfort but only since I paid extra to upgrade to business class. World Traveler Plus is mediocre at best."
Cons: "Boarding process was chaotic."

Pros: "Professional pilots. Good flight."
Cons: "Unprofessional and rude flight attendant. Not enough food available on an 11 hours flight."

Pros: "nothing"
Cons: "waiting for boarding waiting for the take off waiting for the meal tired staff broken laguagge at the and no promised phone call from the laguagge department"

Cons: "Showed up 3 hours before departure and still missed our flight. The agents were extremely slow and rude. If you have a giant line of people who have missed their flight your system obviously isn’t working. Avoid Heathrow’s British Airways by all means if possible."

Cons: "The food was not that good, the beef was like a brick and the service Poor , I asked for water twice, by the time it arrived I already had finished, same for bread I had to ask for bread, was not offer, if I didn’t asked for the main course in the lunch portion on the flight they were taking away the tray after the salad and fruit, I did not like the salad, I tried mine and my Husbands that was salt restricted and they were Awful. I travelled business class, the flight was packed."

Cons: "The credit/debit card machine didn't work on half the cards. It took about an hour for anyone to get food or a drink. The staff was more preoccupied with selling things than picking up the rubbish. It only takes a minute to walk down the aisle collecting cups and bottles. Some people never did have their items collected before the three hour flight ended."

Pros: "Premium Economy seats LHR-SAN. Comfortable, decent food, nice variety of entertainment. This flight is the best way to get from San Diego to Europe."
Cons: "The TV portion of the entertainment system didn't work, but there were enough movies to keep me occupied for the 11 hours of the flight."

Pros: "see above"
Cons: "see above"

Pros: "In flight entertainment, food and everyone was great!"
Cons: "No issues"

Pros: "Crew was nice. First time ever that a stewardess removed my vegiterian tray early while others are eating so I can move in my seat"
Cons: "I was frustrated that I could not choose my seat on my on line check in. I thought at that point one can choose their seat. This happened to me on my way previous flight on BA and nothing was fixed on the app"

Pros: "The service was great, plane was clean, entertainment was great, food was OK but not great."
Cons: "In economy the seat spacing was very limited. It was worse than many US domestic flights. If the seat in front was reclined, the TV screen was about 12-15 inches from your face."

Pros: "Crew is super hospitable and nice"
Cons: "They lost my luggage after I asked when I checked it in LA and when I boarded in SD"

Pros: "The crew apologized for the late departure"
Cons: "We were left waiting for the technical issue to be fixe for more than an hour"

Pros: "Crew was friendly and polite, food was ok, decent entertainment system. Plane was new and clean."
Cons: "Seat pitch was small and not a lot of legroom. When passenger in front of your folds his seat, the seat back is mere inches from your face. Cabin announcements were too loud in headphones."

Pros: "The flight was pleasant"
Cons: "That my luggage is not here and I have no idea when I will have it"

Pros: "good entertainment"
Cons: "food was worse than typical airline"

Cons: "The service wasn't very good. We had to walk to the galley for drinks mid-flight."

Pros: "If I had another option for a direct flight to London, I'd take that over traveling with BA."
Cons: "They ran out of the meat option for my meal. Understandable but I couldn't eat the veg option either. The flight attendant literally said to me that they had no other food on board - a complete lie of course which I didn't appreciate given the $1500 ticket I paid for the flight."

Pros: "Crew is very nice"
Cons: "Seats are pretty small"

Pros: "The food was decent and the tv's offered a number of movies and options to pass the time this was my first time flying with BA and I would fly with you again. Much improved from AA and United"
Cons: "The crew was fine, but not overly friendly. I flew BA to and from my destination. The other flight, the plane was nicer/newer possibly."

Pros: "The food was good. They asked for people with carry on to check their baggage at the gate. We were the only ones that did and they rewarded us with priority boarding. Nice touch."
Cons: "Non stop London to San Diego, 10.5 hr flight. Like most airlines the fit was so tight that by the end of the flight I never want to fly again."

Pros: "Food and service were first class even in economy seating. British Airways is always my favorite airlines, consistently superior in most areas. The food and beverage on the 24hr flight was very good."
Cons: "The Boeing 747-400 on leg from London to San Diego had the older infotainment system, compared to my first flight. It worked well, however the screen was small, and the in flight flight tracker was dated. Most BA flights have the newer system."

Pros: "Boarding at LHR was so quick. This was my first 747 experience and the boarding process for so many people took less time than other flights I've had with smaller crowds. The entertainment was great, flight staff was very cheery, and there was food being served nearly every two hours..."

Cons: "Seat backs are too thin. You feel every time the person behind you goes into the pocket."

Pros: "BA always has the most pleasant and accommodating flight crew. They go out of their way to make me feel special on any flights I've taken with them. Other airlines should take note. Thanks for a great flight."

Pros: "The treatment and luxury of being a business/first class passenger. I've been told I was (free) upgraded from economi class to business class. Actually there was no business class,- it was first class. Because after arriving and leaving the aircraft, I walked (like everyone) through the First class,-and it looked exactly like the "business class" I was sitting. I had all the luxury and service a first class passenger had,- from the champagne and all other amazing beverages to the high end luxury dining and of course the amazing service of the flight attendants. I would always choose BA again if Ihave the choice. Even if it's still "just" economy class. BA is just an airline that treats all their passengers as first class member. Thank you BA for this experience. Keep it up and please, never change."

Pros: "Courteous service, and good selection of new movies"
Cons: "Turbulence over the mountains, and steward didn't serve food anymore"

Pros: "Service flight crw"
Cons: "Terribly crowded"

Pros: "Everything was excellent, except the entertainment. e."
Cons: "WiFi was a problem. All four flights were delayed. Movie sound was terrible."

Cons: "Seems like the easiest way to make flyers happy is a decent TV with movies on the flight, not this airline. The entertainment consisted of a a 4-6 TV in the back of the seat in front of you that occasionally turned black and white. Time to upgrade that BA!"

Pros: "It was professional ,efficient ,enough service for the 10 hour flight. I would like to see more choices for the music selection."

Cons: "Flights over 10 hours should be on a more comfortable plane with electrical or USB ports. I had an 8 hr flight from jfk to Rome (Finnair/American) was on a very comfortable plane with better entertainment and charging capabilities. however, the 11 hr flight from London to SAN was more cramped, no charging, fewer entertainment selections and all around uncomfortable. I expect more from BA on such long flights."

Pros: "Meals and customer service"
Cons: "Seats. Absolutely no legroom or body room in economy seats. If you are making larger planes, you expect a more comfortable ride. Not the case at all here. In fact in the upright position, you seem captivated"

Pros: "Staff. Ample seat recline."
Cons: "No usb outlets. Dated entertainment. No indiv air flow control. Screw was loose and a metal wire was wrapped around but you couldnn't see it. So, when I reached to turn the broken dial for air the metal wire pierced my finger."

Pros: "It was Mother's Day and also my birthday and we got upgraded to European Travel Plus ( business class). It was great"

Pros: "Food was good, flight attendants on horribly delayed flight still gave good service."
Cons: "Delayed 5.5 hrs, on the way out online check-in wasn't working & got booted out of previously reserved seats into middle of middle 4. Attendants seemed to ignore middle seats. On flight out, entertainment system was down for first 4 hours of 10.5 hour flight. Long international flight & only 1 drink service besides with meal. Prepare against dehydration by bringing your own water. I don't think I will be flying British Airways again in future."

Pros: "Comfortable"

Cons: "Not enough washrooms for # of people. Denied us of from WR. Food carts blocked WR access to most people for long periods of time."

Pros: "Aair Canada rouge seems to ne a plane for cattle. Too tight"
Cons: "Human space between seats"

Pros: "On time."

Pros: "Smooth flight"
Cons: "No entertainment unless purchased. Seats were very tight -no leg room"

Pros: "You got me there without problems. Even the baggage got transferred. Better if seats declined more. I would pay an extra 40 to have a more seat recline."

Pros: "Everything, we were on time and everything was perfect."

Pros: "We got there without crashing."
Cons: "Checking in and luggage drop off was chaos. One useless staff person failed to tell people where to line up to drop bags off until the end. She just stood there and if you asked a question she gave you the wrong answer. In Newerk we had to wait 2 hours for our bags. The man st the AC office had no idea why the bags were not coming and could not get someone to tell him and emotionally dithered and then fell apart. I will avoid travelling on AC again if I can. Worst flight ever. They did not have enough food on board either. At least the pilots were competent."

Pros: "Comfortable aisle seat"
Cons: "Better first class deals"

Pros: "I like that we made it safely."
Cons: "The crew seemed to not like their job and were very short with customers."

Pros: "No water in washroom No coffee , Coffee machine do not work Food is for purchase and the whole menu is not available except one item only crew are not friendly No head phones for entertainment I will NOT fly with Air Canada again unless I am forecd to do so"

Pros: "Boarding was efficient"
Cons: "Flight was cold, movie and tv choices were poor."

Pros: "The plane didn't crash."
Cons: "The trip took about 48 hours. After a cancelled flight I got no hotel discount. Several flights were delayed or cancelled and in the end I ended up just going to a city 3 hours from where I live and renting a car to drive home. My luggage still hasn't arrived. This was the worst, most stressful travel experience of my life."

Pros: "I had wheel chair service for transit"
Cons: "Layover time was not enough. I got 1 hour or so for transit. Ridiculous short"

Pros: "The boarding was smooth. The attendant at the checking was very friendly and courteous, the website information on the luggage weight was incorrectly worded and we had to transfer some of the clothing to a carrying on bag. The wheelchair attendant was very friendly and courteous she made my mother feel relaxed since it was her first time traveling alone as a disabled person."
Cons: "A snack should have been served. Only juices were served. An announcement should have been made for layover passengers to purchase food at the airport if they are unable to purchase on board with a card."

Pros: "Crew was professional."
Cons: "Why not due the security briefing while we are sitting there delayed?"

Pros: "I was not on this flight I flew raleigh to Toronto to Montreal to geneVa but I bet it was a great flight!"

Pros: "I liked that at 3 am I finally got a room"
Cons: "The farthest I got in 2 days was Toronto Canada"

Pros: "The flight crew were wonderful to interact with and really helpful in accommodating my disabilities. Dinner was mediocre but at least some was available, which I didn't expect on an overnight flight starting after dark. ("Breakfast" was a slice of really tasty banana bread but nothing else.) I really appreciated the presence of outlets and USB ports for charging electronic devices, and that the seats had adjustable headrest flaps. These are essential features on long flights!"
Cons: "It's almost impossible to sleep in economy class seats, even with the adjustable headrests. I recognize that economy is supposed to be the "no frills" class of travel but sleep is not a luxury. Sleep is a basic human need, like food and oxygen. I don't actually believe that offering better accommodations for everyday passengers (off whom the bulk of airline profits are made) is financially unfeasible or unreasonable."

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!"

Cons: "Food was purchase only."

Pros: "On time"
Cons: "Not comfortable at all, seats are too crowded, and cabin was way too hot!! Some ppl had to undress their babies..."

Pros: "The flight was perfect. Stress free. I will definitely get it again."

Pros: "Not much"
Cons: "Cramped seating. Bare bones IFE that barely works. Not even a bag of pretzels for free. Gate agents seemed baffled by the boarding process."

Pros: "Short flight"
Cons: "Coming back, the drinks and the declaration cards came too late. We were landing when I got a Cole."

Pros: "Crew"
Cons: "Ridiculously little room on rouge flights. Sad. Choice of movies not great.food on offer mediocre. Everything else ok"

Pros: "Entertainment"
Cons: "Crew was rude and poor communicators."

Pros: "All"
Cons: "None"

Pros: "Airplane features like the comfortable seating, leg room and window dimming capability. Head rest entertainment center and Flight Info graphics were great."
Cons: "Overall the crew seemed bored and tired with their job. On-board announcements sounded disinterested, and crew seemed tight and not overly pleasant."

Pros: "Aircraft was originally booked solid, but a last minute change of aircraft switched us to a larger aircraft so everyone could spread out and get a little more room. Crew was energetic, enthusiastic and pleasant. Overall the flight was above average, mainly due to the friendliness of the crew."
Cons: "Leg room in economy is always an issue (I'm 6'4"). Thankfully this flight was not booked solid and there was no one sitting in that dread middle seat. The food was Mediocre at best. We ordered a pizza for lunch, the toppings apparently shifted in flight and the cheese and pepperoni slid off the crust and was sitting on one side of the box with the crust on the other... (Advice - Stick with sandwiches, crackers and cheese, etc. instead of the hot meals on Air Canada)."

Pros: "On time."
Cons: "Food wasn't that good. No screen on back of seat to see progress of flight."

Pros: "Nice crew. Smooth boarding."
Cons: "No televisions on an international flight. Yes, they have an app with movies but a friend couldn't connect to their wifi so was without entertainment. My seat was more comfortable on my DC-Montreal flight than my international. Warn customers about the difference between Air Canada and Air Rogue. Big difference."

Pros: "Reliable. Easy to board. On time!"

Pros: "the crew members were friendly"
Cons: "that you don't give any snacks for price of ticket. at least peanuts or pretzels. that's ridiculous. southwest reigns."

Pros: "The fare was low."
Cons: "The incoming flight was two hours late, but AC did not notify us to tell us of the delay."

Pros: "I liked all the assistant they gave to make a person comfortable."
Cons: "That we had no choice for the seat on the plane"

Pros: "There was a decent selection of in flight movies"
Cons: "-the aux plug for the headphones wasn't working properly. Resulting in me having to hold the headphones in place the entire flight -the first time the attendant went by with the food selections for purchase she walked right past me and went on to run out of food by the time I finally got her attention. -I had to ask the people behind me several times to please stop their child from kicking the back of my seat. Although the attendant made eye contact me one of the times she made no intervention on my behalf. - my return flight was in short: neglectful and arduous. I probably wouldn't recommend Air Canada after a flight like that."

Pros: "Nothing"
Cons: "Never flying Air Canada again!!!!"

Cons: "Someone else was sitting in our seats and when asked they said they had lost their boarding pass and hence don't know their seat number. I called the flight attendant for help and he checked our boarding passes and asked us to wait at the back of the plane. He stood there for another 10-15 minutes and we were not helped. Finally, another flight crew member came down to the back and asked us to sit in a row almost to the back with barely any legroom. I am 6'2" and was cramped into the seat. It was horrible!!"

Pros: "none"
Cons: "bad service and didnot tell customer some critical information"

Pros: "SAME AS ABOVE."
Cons: "."

Pros: "Loved the leg room. Flight was on time and got our luggages on time, flight attendants were very nice and helpful! overall flight was very comfortable. will fly with Air Canada in the future again :)"

Pros: "Boarding was pretty quick, efficient, on time"
Cons: "Seats had least legroom of any plane I can remember. I'm not that tall and my knees were in the seat pocket the whole 5 hr flight. Also, the seats could stand to be a lot cushier. I felt like I was sitting on a piece of cardboard after the first 2 hours."

Pros: "Crew Only."
Cons: "AC website states for US and Canada allow 120 mins. We arrived to the airport 130 mins inadvance. We had no checkin bags but we almost missed our flight. (Many people did miss our flight). You need to allow at least 2 -3 hrs for US security checks. Because we almost missed our flight, we didn't have time to purchase food preboarding and the selection in the plane was very limited. My partner is 6'1 and the seat was extremely uncomfortable for him and it was not in our budget to upgrade. There was no free entertainment in the plane. You needed to rent a tableT!"

Pros: "The person we sat next to. And the great flying of the pilots."
Cons: "I am handicapped. Requested a wheel chair from the curb . Upon arrival, no wheel chair. we waited and waited. Then my friend went and got a wheel chair for me. we then joined our two friends, who also had wheelchairs. however, they had first class and was taken immediately to the first class lounge. I was waiting forever behind the check-in desk in Vancouver. I then put my bags on my chair and used the chair like a walker! Still no help. When I asked for help I was told that I was early and I could wait. Not the right answer. I was told to be at the airport 2 1/2 hrs. early which I was. Until I got to the woman at the boarding desk at E84, I was treated terribly. Since we travel with our friends we had hoped to at least see them. No way. Air Canada mad sure of that. also Not a peanut unless we spent money!!!"

Pros: "I liked that the head rests bent so I could rest my head on something"
Cons: "There is not a lot of legroom back in the economy section - I'm 5'7" and I kept hitting my knees on the back of the seat in front of me, so if I was any taller that would have been very uncomfortable."

Pros: "The crew were friendly and the food was pretty good."
Cons: "There was no music/entertainment provided by Air Canada. No flights over 4 hours should be without monitors for movies and/or music. Being told in-flight that we could have downloaded the Air Canada app was inexcusable as one couldn't download anything during the flight. I've been on many flights and the only other plane that didn't have entertainment or music options was going from Cape Cod, MA to Nantucket; a 20 minute flight on a Cessna. I was not expecting any music or entertainment on that flight, however. My wife and I were very disappointed in Air Canada from this perspective. We have 4 children and would pay extra on different airlines would never fly it again. We were grateful from Toronto to DFW there was entertainment, though."

Pros: "We liked everything about our flight, except my husband lost his luggage and it is not found, one day later ! ?"
Cons: "Lost luggage"

Cons: "We were three hours late"

Pros: "The plane was thoroughly clean, new interior, and state of the art technology in every seat. The service was prompt, but I was not as impressed with it. I am allergic to nuts and questioned if the food they served contained nuts. The attendant told me she could not guarantee there was not and showed no empathy in the situation. The attendants did not smile as much and had flat affects. Aside from that, the flight was smooth and wonderful. It was the best flight I have ever gone on!"
Cons: "Lack of knowledge and empathy regarding food allergies and what their food contains."
