Airline reviews

Pros: "I had a cheap ticket and expected much less, but food was great, crew was creat, boarding was easy."
Cons: "The boarding was on small plane parked far away from the terminal and we had such a long bus ride I started to think "what is going on"..."

Pros: "Staff were accommodating and considerate, great flight!"

Cons: "Delayed flight meant missed connection and had to stay overnight. Very little communication from the airline about what arrangements were being made. Was also unable to check in online on either leg."

Pros: "They help get passengers to seat and with their luggage"
Cons: "They insist to wake you up if sleeping to ask if you want to eat instead of leaving you alone!"

Cons: "Food"

Pros: "Business class is the best"

Pros: "The purser and the business class cabin attendants were amazing. Great choice of meals. Fantastic experience"
Cons: "Nothing."

Pros: "Crews were excellent. Luggage came out very fast. Flight was very comfortable."

Cons: "maybe they can offer more snacks on the plain"

Pros: "Crew were so good"
Cons: "Everything is good"

Pros: "Nothing"
Cons: "All the food was terrible breakfast lunch and dinner I was sick from eating chicken I started vomiting as soon as I was on my way home , please serve better food , food tastes like factory junk , please offer cold drink and cold water or least ask if you would like ice, all the cups for the beverages was small, seating was very uncomfortable not enough room especially if you sitting next to a large person they kept elbow me and taking up my seating , I was so miserable on a 16 hours flight on Qatar to LAX , very bad experience , please do better, also staff was not friendly"

Pros: "nice crew, great service"

Pros: "Qsuite is the best flight experience I've ever had by a long, long way."

Pros: "Helpful,courteous and efficient"
Cons: "Wifi was hard to connect"

Pros: "Excellent service with attention to detail"
Cons: "lay-flat seats fairly uncomfortable in the lay-flat position (does not compare to the Q Suite used on newer aircraft) Entertainment system a bit dated, but decent selection"

Pros: "New plane and Q suite was excellent"
Cons: "The AVML selection could be better"

Pros: "exellent in everything"

Pros: "Good crew, fair choice of food and drinks and served whenever you want it. Good array of entertainment on offer but our flight was a 'sleeper' so after a fumble with the controls and the limited new releases, I opted to read instead. Not sure we like the Dreamliner configuration and levels of comfort more than the 777 or Airbus offerings but it was fine."
Cons: "A couple on our flight decided it was OK to have their 4-year old run around the cabin shrieking and causing a lot of fuss. Most of us in the cabin complained but these parents were pathetically weak and elected to allow it to continue. No sleep... spoiled experience.. miserable flight in this respect. Terrible Business Lounge 'Aspire' in Gatwick; dirty and poorly equipped - not even Prosecco on offer without paying £5 for a small glass. Qatar should stop using this dreadful place. Crew seemed to have stopped referring to the passengers by name and offer a less-personalised service in Business than we have become accustomed to. The food choices while good, have been paired back as have the selection of wines."

Pros: "The plane was very new and wasn’t crowded."
Cons: "The arrival time was slightly delayed but overall it was okay. The hot food again can be improved as the chicken dish had no vegetables (even though there was a side salad dish). The waiting lounge at Doha airport gate was a bit cramped, and the bus ride from the gate to the aircraft was also a bit long."

Pros: "Qatar beats every US based airline, hands down! The planes are clean and modern with better seats, leg room, technology, food and staff. Everything is included in the cost of a ticket, something that US airlines should learn! I cannot say enough about the experience and wood recommend to anyone traveling to destinations served by this airline."
Cons: "I cannot think of a single thing."

Pros: "We felt home every thing was comfortable from A to Z- unforgettable trip"
Cons: "None"

Cons: "Had an 11hr delay overall, 3.5hrs sitting on the tarmac only to be told to disembark for dinner at the airport. Then told that we won't be getting on until 7am the next day, but only really started boarding at 8:30am. By the time we were told about the reschedule to the next morning, it was too late to get a hotel room (too far away) and was told that I could use a 'Quiet Lounge' at the airport (which wasn't quiet). While waiting to board at 7am the next day, ground staff told us that they had to change the plane so there would be a further delay. On boarding, we discovered that it was the SAME PLANE."

Pros: "Good movie selection, very friendly crew"

Pros: "Everything"
Cons: "None"

Pros: "The food and the crew were excellent. Highly recommend the chicken massals"
Cons: "The seats in economy class were a little too close for comfort"

Pros: "The ease of connection from New York to Nagpur. It was a breeze."
Cons: "My personal headphones (Beats) couldn’t be used in the headphone socket which was a bummer. Also, the only male guy in the crew was trying to solve some meal issues and was trying to tell the hostess how not to tell the passenger!! All of it could be easily conveyed discreetly but he seemed to be least bothered!"

Pros: "Service, attentiveness, food."
Cons: "lack of ability to pay to upgrade even though there was plenty of empty business class. (Almost all seats were available)"

Cons: "they need to do family section"

Cons: "Boarding at JFK very disorganized. Poor system. No vetting of wheel chair users many fakers."

Pros: "The Crew The food"
Cons: "Transiting. Made to stay in the airport for over 8hours after a 9hr 35mins flight. I was not happy about it. I hope that, on the return journey, when transiting time would be over 10hours, i would be lodged in a hotel. Thank you."

Pros: "Comfy, good food, good service"
Cons: "No internet. Limited movie options."

Pros: "Philadelphia-Doha was excellent and noticeably better than Doha-Bangkok. ood, service, condition of aircraft were all better in the PHL-Doha leg. I have done the trip a few times now so it is not a fluke. Odd that the Doha food (and I usually get the local dishes) is very so-so. I usually only take a bite or two. Not appetizing. The Doha-BKK staff was less professional as well. The trays of the main meal were left with the passengers so long, we passengers started to bring our own trays to the galley. The plane out of Doha was very tight so passengers in economy have that sardine experience. The cup holders did not work although they would have been useful."

Pros: "Everything"

Pros: "The friendly hosting of the crew and the clean and tidy of everything the food was delicious hot and cean"
Cons: "The alcoholic drinks on the craft had to be banned for sack of God"

Pros: "Excellent flight , seats, food"

Pros: "Food was great. Attendants were courteous and nice. Airplane very confortable and clean."

Cons: "The crew at the ticket counter was quite rude. Our suitcases were 2kg heavier so, in front of them we opened and removed items and then they still made us go through security all over again"

Cons: "they pot me in another flight"

Cons: "USD 20 wi fi and you only get 200 MB seems a bit antiquated"

Pros: "I like the staff and the way they treat the passengers and foods too i like , was really good"
Cons: "I didn't like the comfortable part at the plane , it's not that good plane , the spoon ,& knife are not good , the chairs are not comfortable that much as the other planes of Qatar airways,"

Cons: "We had to wait for about 5 years, more than 3 hours unscheduled wait. During this time we were provided with a very poor breakfast."

Pros: "My family did not comfortable in English talking and air hostess helped them very good with Hindi language. Increased my mom confidence to travel through Qatar airlines without any problem. Appreciate staff on board and airline service, thanks."

Pros: "Every thing"
Cons: "Nothing"

Cons: "Seats in economy very uncomfortable for long Doha to LAX flight. When person in front of us reclines seat for entire flight, it is almost impossible to get out to stretch legs or go to restroom. At the minimum, crew should ask all passengers to raise seats during meal service as a courtesy to those behind them. This is done on other airlines."

Pros: "Food was great, good selection of entertaiment and movies, seat comfortable (even for economy class). Very friendly flight attendants. This was my first flight with Qatar and I'm now a big fan"

Pros: "Staff were polite and helpful. Flight was smooth and on time. Overall very good considering length of flight and difficulty of accommodating such a large crowd for such a long time."
Cons: "Meal service was very disappointing. 16 hour flight with one meal at the beginning, one meal at end, and a small, rather unappetizing hot pocket like sandwich in between? And snack offerings were ice cream, potato chips, candy bars and a few apples (ran out of apples). Need more healthy options. There needs to be a more full meal/snack offering around the half way mark if you are going to keep people from grumbling."

Pros: "a wonderful experience to travel with Qatar airways, recommended for others as well."

Pros: "The service on this flight was not very good. We almost missed our flight whilst waiting for a wheelchair for mother. She had to finally walk to the boarding gate because the wheelchair we had requested did not come."

Pros: "Food, crew, in flight services and entertainment were amazing. Definitely recommend this airline for trans-atlantic flights."
Cons: "I flew on the Boeing Dreamliner which is pretty loud. I recommend noise cancelling headphones or earplugs."

Pros: "Loved this flight, crew was amazing!"

Pros: "Nothing!"

Cons: "Over 2 hours late, and this flight has been late 6 of the last 7 days"

Pros: "There wasn’t anything to highlight as good. On this trip except LHR was organized and clean. The boarding was a free for all after the elderly and young had been boarded footstep as they should."
Cons: "The ground staff were rude and officious"

Pros: "Lufthansa is always reliable. Flight was fine. The staff were kind and efficient in their jobs."
Cons: "There is no inflight entertainment on these flight but I brought my own."

Cons: "I missed my connecting flight because my flight was late. I had to get to my destination for a wedding."

Cons: "Old plane, old movies, service was mediocre"

Pros: "The crew's efficiency and friendliness"
Cons: "Having to fly to Germany to come to San Diego"

Cons: "Online check-in did not work. When I checked in at the airport, I received only a middle seat."

Pros: "Once again, the in-flight crew was excellent. The flight was good, but no entertainment is provided."
Cons: "Another late take off, probably because the incoming connections were late. So it was good that the airline delayed the connecting flights. However, this leg of the trip was so late that I barely made it to third leg of the trip. A huge problem is that each of these international airports require that you go through the security check again. For that reason, connecting legs of trips through these airports should not be scheduled so close together. Heathrow is the worst, with security staff that, at best, don’t care that you have a close connection to make and just ignore your pleas to speed up the process, and at worst, are just plain rude."

Pros: "Only an hour and a half but perfect service and even a nice meal. Because of the delay there were a lot of questions to the crew but they managed to keep travelers calm and happy."
Cons: "Flight was delayed but that had nothing to with the crew and the service."

Pros: "Comfortable seats, good legroom."
Cons: "Slight delay."

Pros: "Made up most of the time. Latrobe leaving due to queue."
Cons: "That I did not know in advance there was a snack. Would have odered vegan as it was had nothing."

Cons: "They cancelled my flight"

Pros: "Nothing"
Cons: "No body helped me. My first flight got delayed and missed my connecting flight. People were rude and showed that they didn’t care. I had to wait 4 hours for the next flight. I received little compensation"

Pros: "The counter staff in Heathrow was great"

Cons: "The flight"

Pros: "On time and good service"

Cons: "N/a"

Pros: "I upgraded to the premium food package for a small price. It was delicious and filling."
Cons: "The quality of the sound from the earphones was not very good so that made the movies less enjoyable."

Pros: "Food is worse"
Cons: "Too crowded"

Pros: "Easy check-in and helpful staff. I would absolutely fly with Lufthansa again"

Pros: "It was good the checking desk person was polite and done her best to put get me on to British Airways flight to get to my destination on the same day."
Cons: "But we waited tilll 12.30pm still flight took off at 14.00 and arrive in Dubai at 23.50pm instead of 22.30pm person went home who suppose to pick me up. I got to the place I was staying at 01.39am which was very uncomfortable. I will never fly again with Lufthansa Airline it use to like British Airways but definitely they have lost the customer touch."

Cons: "The plane lands a considerable distance from the airport, you walk across the tarmac in the rain to a bus, and then the bus ride is almost 15 minutes. I expect Lufthansa to have a better berth at Frankfurt."

Cons: "Flight was 30 min delayed . When we landed, the jetway was someone mispositioned and it took even longer to get us off the plane - nearly 1 hour late. Missed my dinner appointment as a result and generally bad start to my trip to Munich . Very disappointed ."

Pros: "Awesome"

Pros: "The flight itself was fine."
Cons: "Getting to LHR early for. 6:30 am flight was no use since they don't have any departing flights between 11pm and 6 am. So we were stuck in the lobby for hours until ticket agents arrived at 4 am. There was one open coffee shop however. Then we waited for security to arrive at about 4:30 am to get through and it was quite a slow shake down. One through there were no restaurants open until 5-5:30 am. The flight itself was fine. Facilities at Frankfurt were minimal with toilets offering only one stall each. While standing in the long queue a lady and her young daughter were rudely ushered out by the male custodian for cleaning, and then it could not be used for another 10-15 minutes."

Pros: "Was informed that boarding would be delayed but began within minutes. Arriva time was spot on"

Pros: "Horrible customer service through the strike. Rebooking took four hours."

Cons: "Most cramped seat I've ever sat in. Couldn't even sit because my knees hit the seat in front, before my but was in the chair."

Pros: "Even on such a short flight I got a sandwich. It was a salmon sandwich which I never had on any other flights. They usually serve cheese or ham or chicken in the Middle East. It was nice to have something different and nutritious."

Pros: "Priority boarding with small kids"
Cons: "In London I was required to ask fro this priority boarding with kids if not asked I would be queuing with small kids for 15 minutes.. (whilst In Frankfurt we have been invited to be boarded as first ones without asking for it.)"

Pros: "The price for a direct flight was reasonable"

Pros: "Staff was friendly. They fixed my flight from Frankfurt to Denver and got me an aisle seat."
Cons: "Leaving late from BOTH legs on the way to England. :-( Being told in email that I was going to have an aisle seat on the flight from Frankfurt to Denver, but then on the day I was told I wouldn't."

Pros: "Heathrow had a lot to offer between flights. Our gate was in the middle of everything."

Pros: "On time, nice and professional personnel, kids-friendly, tasty & free food & drinks. Great airlines every time!"

Pros: "I loved how friendly the airline attendants were."
Cons: "I didn't like how in the Munich airport I couldn't find a place to plug my phone in. they should make those more accessible"

Cons: "I was nauseous during the plane ride walked to back of plane and was told I wasn't allowed to be back there. When that is where the bathrooms were. I asked for an extra pillow when there were 10 free seats the crew never honored my request. Not once did they ask if I was ok. The food was inedible. And I was completely uncomfortable the entire flight."

Pros: "The whole flight was very comfortable"

Pros: "The crew was professional & friendly"
Cons: "Food was terrible honestly, entertainment system didn't work on 1st flight."

Pros: "the crew was wonderful, we got a nice Wrap and water, wine or coffee for free, not all airlines serve it anymore, we were on time and I got whatsapp message with updates of the flight"

Cons: "Flight got cancelled"

Cons: "I was seated next to the restroom, which is not a pleasant experience for an international flight."

Pros: "Crew was great and helpful despite oversight in my special meal."
Cons: "Special meal request was overlook. I did not mind so much as eating less does some good! It is human to err!"

Pros: "Just as I expected. And I made my last connection easily."

Pros: "Crew great, boarding at Nice very organised, boarding in Amsterdam not so organised!"
Cons: "A queuing system would be better-it was a bit disorganised at Amsterdam!"

Pros: "Travel on Crostian Airlines did not pappen. KLM flight to Munich was cancelled and I was rescheduled on Air Setbia to Belgrade, the Split."
Cons: "That it didn’t happen."

Cons: "Nothing good to say about this flight. The plane was old with no entertainment. The sits where very compact and not comfortable at all. The food was a sweet bread and water. The flight attendants were rushing and will take a while if you needed anything. I felt like I was taking a bus with graffiti all over the place."

Cons: "Unaccompanied minor flying to Lisbon overnight. Bag was lost. No real effort to assist. Bags of unaccompanied minor should be treated with priority."

Pros: "The staff was very helpful and professional. Promp response to calling for attention."
Cons: "Wish there was better lumbar support for the seats. The food could be a bit more exciting with simple addition of lime pickles. Overall can not complain for economy standard!"

Cons: "Flight was delayed by 2 hours. Could have gone to Amsterdam and come back in that time"

Pros: "In flight food was enjoyable"

Cons: "It was announced I can choose between fish and chicken meal but when I requested for fish meal, I was told it’s finished. My seat was 21, and it surprised me. If something can be changed about that then your services would be much appreciated. Thank you."

Pros: "Good multi media access and content"

Pros: "I was pleasantly surprised they had a snack service on such a short flight. The flight attendants were very friendly"
Cons: "Amsterdam customs is the most disorganized I have ever seen. With the number of tourists entering the country you would think they would have done something about it. There were only 2 customs agents!! One for all passports and 1 for all passports. We were in the customs hall longer than we were in flight!"

Pros: "Priority boarding was appreciated and the flights were on time. Service was fine. Schipol was good."

Cons: "Not only was there free food but they tried to sell you a bunch of stuff. Not a moments piece."

Cons: "They didn’t let us board the plane. Allegedly the plane was changed and make us travel by train!! They offered us a compensation but we haven’t heard from them yet. Not good experience at all."

Cons: "The entertainment was quite dated and didn't have new movies etc"

Pros: "captain was great."

Pros: "A nice short flight"
Cons: "We had booked business on our flight to Milan, and it was extremely disappointing that on this sector they put us on the last seat in the back of the plane. There were plent of seats on this flight that had extended legroom. A bit of a mystery, why Westjet elected to put usin the last seats on the plane?"

Cons: "Lost bags"

Cons: "I was not expecting to get on a full 8 hour flight with no meal unless I pay for it. Although the mistake on purchasing a flight without meal may come from my end, this logic of having to pay for a meal is not ideal whatsoever, this should never happen, especially when going on a 8 hour flight, meals should always be included regardless! never heard of this ever in my life of using westjet for 7 years , very disappointed."

Pros: "Excellent airplane, the Dreamliner is amazing with great leg room (I'm 6' 1") comfortable seats and head rest, great lighting and an extensive entertainment system! Crew was efficient."
Cons: "The food was terrible. Cardboard packages that contained tasteless meals."

Pros: "The crew was doing best for the circumstances of old aircraft and greedy airline."
Cons: "Westjet planes operating on the London-Vancouver route have no screens at the back of the seats. The entertainment system provided over wifi is impossible to connect (spent almost 2 hours trying until giving up) and internet is not free too. There is only paid food on this flight (~ $15 / meal)."

Pros: "Price was excellent"
Cons: "Long delay in Calgary for omward flight. Mass confusion at boarding gates."

Pros: "The crew was fine and we were very comfortable. This is because we were in Premium seats. The experience is entirely different in economy, which we did while flying the other direction."
Cons: "The Westjet employees working on the ground as we disembarked in Calgary we’re not good. It took forever to get out stroller off the plane, and one employee was being really rude to all the people waiting for their strollers."

Pros: "Member of the crew was not too helpful. Despite my malfunction"
Cons: "Customer service. Understanding customer needs and provide best possible travel experience."

Pros: "Crew was great! Seats were decently comfortable. On the way there the travel time was shorter than expected. s"

Pros: "Crew was awesome, very friendly"
Cons: "10 hour flight, and you pay for gross food."

Pros: "The flight staff were excellent. Very pleasant to deal with and very accommodating. They really let you feel that they were there to help and if they could they did."
Cons: "The only real irritation was the check in process. I have no issue whatsoever with the 23kg allowance per bag but the process for checking your bag, especially if you were over the limit and what the consequences may be were not obvious. My wife and I had two bags, mine was 4kg under the allowance and my wife's was 2kg over. If I had known this was going to be a potential GBP45 charge we would have shuffled things about to balance the bags. It needs to be made clear to people that they can actually weigh their bags first to find this out. My bag was already tagged and gone when we went through a lot of hassle to reduce my wifes bag weight. Anyway, this is a suggestion so that future passengers do not encounter the same frustration."

Pros: "I didn't!"
Cons: "Late, late, late! I was a prisoner in my seat."

Pros: "From checking in to my arrival I enjoyed the service. The crew even on ground were helpful at the checking in. The light refreshments were okay. I am impressed. I had no on board entertainment so can’t comment on that."
Cons: "Nothing in my whole experience with WestJet on my trip."

Cons: "Leaving Gatwick 30 minutes late had us miss our planned Halifax to Toronto. The next flight was 4.5 hours later. After a trans Atlantic, that is horrid."

Pros: "Most of the crew were nice. Captain very informative."
Cons: "It was freezing! The headphones they rented me didn’t work, or maybe it was the tablet—could barely hear the movie."

Pros: "Boarding etc was organized and efficient."
Cons: "Did not find the crew helpful or friendly."

Pros: "I like the head rests that move and the GF options. The flight attendants were fabulous."
Cons: "No meal for a long trip. 9 hours is too long with out offering food no matter the ticket cost. Also, having entertainment at every seat would be more welcoming"

Pros: "Enough space for long legs."
Cons: "Need more variety in snacks on the longer trips."

Pros: "The crew. Very friendly and helpful"
Cons: "The food. Pizza was bad."

Cons: "Unable to hear updates from the crew. Sounded garbled"

Cons: "As it was a budget flight, all food had to be purchased and the cost was high for the quality received"

Pros: "I liked the fact that boarding was a good experience"
Cons: "The fact that the plane was supposed to land at 3.35pm and we actually landed at 4:40 and for some reason we waited to get off the plane with no apology from anyone. The service was not satisfactory and they broke our stroller."

Cons: "No free food was offered on a 8 hour flight. I won't choose Westjet again."

Pros: "The basics were all up to standard, the flight was very full and because it's such a long flight it is expected to have a few discomforts from time to time..."
Cons: "TURN DOWN THE VOLUME on the announcements, it was so loud I could feel the book I was holding in my hands literally vibrating. I had to plug my ears to tolerate the blasts over the PA. I requested the volume be turned down repeatedly but it was never changed... from London to Calgary. More frequent offers for food/beverage would be appreciated, there were only two rounds made for the entire flight of almost 9hrs. It's just nice to have a bit more flexibility..."

Cons: "The complimentary in flight movie would not run on my android device. It ran for 5 minutes then froze."

Pros: "Very fast today"
Cons: "Man these flights are boring"

Cons: "Food charges + hours to wait for a hot drink (tea)"

Pros: "The friendly company of stranded passengers before and after boarding and crew who did their best not to get rattled."
Cons: "It took so long to get home and it is a long trip anyway."

Pros: "Piot gave clear and timely announcements as flight was delayed do to weather,. In-flight crew were friendly and providing a relaxing environment. The include meal was very good."
Cons: "Plane is showing its age. Bathroom was in terrible condition."

Pros: "Crew was great cabin service was good, entertainment was good"
Cons: "Start loading at 10 takeoff at 11:45 late because of loading luggage. Maybe if we start loading at 11 we would not have to sit ther for so long"

Pros: "The economy class seats were surprisingly comfortable."
Cons: "It's a personal taste thing, but I don't like flights where it is necessary to separately purchase all the normal things that other airlines provide on international flights (blankets, wine, food, etc). I'm sure others appreciate that level of economy, however."

Pros: "Cancelled the flight and was utter chaos with no direction what so ever."
Cons: "Staff would not communicate with the passenger's."

Pros: "No Comments."
Cons: "The Female Stewardesses either conveniently did not see me sitting in the middle row seats, or perhaps had other alternative means. I felt totally and absolutely ignored, particularly when Meals and Beverages were being served."

Pros: "Friendly crew"
Cons: "Terrible food options. Sandwiches and croissants vastly overpriced: $8 for a croissant ($1) with a slice of cheese (25cents) and ham (50 cents) is ridiculous. Flight delayed on the ground for 1 1/2 hours."

Pros: "The crew was nice enough, although I did overhear them talking negatively about some other customers out of earshot."
Cons: "The food options were pretty poor for an eight hour flight. I'm happy I brought some food with me because there were few options (snacks - biscotti and party mix, no meals). They also charged customers for checking a bag; most airlines allow the first checked bag to be free for international flights. Not the case here."

Pros: "More leg space than I was used to and pretty spacious bathrooms (I'm 6'5")"
Cons: "The purchased Wi-Fi went down immediately and didn't come back up until 8 hours into the 10 hour flight."

Pros: "Food was great and fresh. Staff was friendly and gave us extra snacks for the kiddos."
Cons: "Took a very long time to serve any food or drinks after being told we could order at anytime, tricky with two little kiddos."

Pros: "The lead crew member was extremely positive and apologetic and at the same time he was very entertaining whenever usually-boring announcements were made to the passengers."
Cons: "It sucks that the crew had to deal with so many angry passengers after we were stuck on the tarmac for 2 hours and in the gate for 1 hour, with a total delay of 3 hours, causing many other passengers to miss their connections. That said, the crew did their best to remain positive and accommodating."

Pros: "Our choice to pay the upgrade to Plus seating was WELL worth the cost. My husband and I had never flown 'first class' before and thought on this almost 9 hour flight we would give it a try. Wow! Seat comfort was fantastic. Service was wonderful. Food was great. We were made to feel like royalty."

Cons: "The toilets were very dirty"

Pros: "The crew were nice"
Cons: "The gate in LGW was one of the farthest in the aiport. The flight ia 8.5 hours and the ticket is not cheap. But you have to pay for everything. Even onvboard entertainment. The only free thing is the soft drinks and that is even rationed. I flew with worst airline and for long flight they at least give a free meal."

Pros: "The return flight was acceptable. seats were comfortable. Would recommend on spending the extra $$ on get extra legroom seats."
Cons: "Flying out on December 24, the airline kept us at the airport for 6 (including 2 hours on the plane) hours before cancelling the flight because they could not get water pressure to the washrooms. We were supposed to leave for London (LHR) at 8:35pm and were notified of the cancellation at approx 2am on December 25. The only other flight that would be available would be on December 25 at the same time the 24th flight was supposed to leave. The service desk was not taking any requests for finding or re-booking flights, we were supposed to call their support number at 7am on the following day. We were offered cab fare accommodation from and back to the airport. They offered hotel stay which I passed on. They provided $60 of airport food that could only be used at certain restaurants, not compatible to purchase chips or drinks (non-alcoholic) from other stores. The coupons as compared to Air Canada, which are valid for a year were only valid for 24 hours. In the end the only "monetary" compensation I got from WestJet was 250 westjet dollars that expire in 12 months."

Cons: "My flight was delayed for 23 hours. It was scheduled to leave at 8:30pm on December 24th. I spent Christmas Day in the airport and in a hotel. Consequently I have no desire to fly with WestJet again."

Pros: "The staff was friendly. The food was great."

Pros: "crew is friendly"
Cons: "more space i am somtired of being cramed in i cant use westjet again due to lack of leg room dont charge for baggage dont charge for food"

Pros: "Ended up getting quite the deal on the flight back and forth between Toronto and London. The flight did leave a few minutes later but nothing unexpected. The crew was very nice and very friendly. The food was decent, they came around for drinks 3 times and twice for snacks (you have an option of pretzel sticks or biscuits and they're both pretty good - I'm partial to the biscuits. Not gonna lie, I was able to ask them for both a couple times, and they obliged."
Cons: "There are no onboard entertainment systems, you must bring your own device and even then their WestJet app has bugs - so the app kept crashing on my Nexus 5X whenever I tried to play a movie or TV show."

Pros: "Nothing"
Cons: "no food, no comfort, no entertainment stuff"

Pros: "Friendly crew (mostly). Entertaining and witty announcements! Like that food is an optional extra, not in with the flight price."
Cons: "Was flying alone with my 8-month baby. At five hours in he needed a break from sitting on my lap. After standing for a while (in the least in-the-way spot we could find) a flight attendant began to get huffy each time she passed and finally asked pointedly if she could get something for us. I offered to go back to my seat which she said would be helpful. In hindsight I think she could have given us a little more grace given the age of the baby and length of flight, or at least have explained the situation more politely!"

Pros: "Both flights to and from Gatwick had major scheduling problems that brought me a lot of stress considering I have a lot of meetings plans right after both arrivals."

Pros: "Nothing. WestJet charges astronomical prices for poor service which cannot even compare with budget airlines."
Cons: "I paid $15 for a meal on this flight seeing as it is transcontinental, and I would be hungry at some point. I chose a vegetarian option. The stewardess dropped off the meal, which was pasta with a side of pasta salad (no vegetables in the vegetarian option..), while I was sleeping. My girlfriend asked for wine to go with our meals, which we were charged for at an additional cost. The wine arrived an hour and a half after our meals arrived. Later in the flight, a stewardess dropped off a Turkey croissant sandwich on my tray table, waking me up for the second time that trip. I called the stewardess back and explained that I hadn't ordered a Turkey sandwich. She explained that a sandwich came as part of the meal I ordered. I stated that I would be happy to receive a sandwich, but that the Turkey did not correspond to the vegetarian option I had specified. She proceeded to take the sandwich away, and did not return for the remainder of the flight. I have issues every time I fly with WestJet; poor performance, service, and customer relations. I've travelled on 7 different air carriers in the last 28 days, and WestJet is by far the worst. I paid €19 for a flight from Munich to Brussels from a WestJet competitor, received excellent customer service from smiling stewardesses, complimentary Beer and Wine, and even chocolate and a snack. I paid over €500 to fly with WestJet, and received nothing but a resurgent sour taste in my mouth. I've given second, third, and fourth chances with WestJet but I believe they have lost my business forever at this point. Truly disappointing to say the least."

Pros: "Normal flight"
Cons: "Normal flight"

Pros: "inbound crew very friendly - nice plane on outbound flight . service throughout inbound flight"
Cons: "Food was not good at all on outbound flight, limited vegetarian options inbound and was not able to select preference prior to flight. staff on outbound flight were unfriendly and service stopped after meal."

Cons: "Whoever designed and built this airplane should literally be INDICTED - AND I AM NOT KIDDING! We were in disbelief the moment we boarded and saw the airplane. 10 people across jammed into the row??!! - and on an long international flight?? - are you kidding??!! Further, these were the SMALLEST seats I have EVER been forced to sit in. Neither I, or my friend came close to fitting. We literally had to alternate getting up and standing because we were literally overlapping each other when we sat! (His shoulder and arm were literally on top of me!!). It was so bad that when the stewardess came rolling down the aisle with her cart, I had to be aware and see her in advance so I could literally TURN MY BODY OVER TO THE LEFT HALF ON TOP OF THE PERSON SITTING NEXT TO ME SO SHE WOULDN'T TAKE OFF MY ARM AND SHOULDER. ULTIMATELY, SOMEONE, OR MORE THAN ONE PERSON, IS GOING TO GET SERIOUSLY HURT BY THIS RECKLESS, GREED-DRIVEN DESIGN!! The OVERT GREED by the airline (American) clearly reflected by this in trying to JAM as many human beings into a flight as possible like Sardines is DISGUSTING!!! You simply DO NOT TREAT HUMAN BEINGS THIS WAY!! It is also clear evidence that there needs to be tighter standards, regulations and penalties by the FAA and what is allowed by airlines. AND I AM SENDING A LETTER TO THE FAA!!!"

Pros: "The crew did an excellent job definitely went beyond good service, I enjoyed the food and they came often offering drinks. It was probabky my first long flight I wasn't thirsty at all. Overall I was very happy with my trip hope thank you!"
Cons: "I got slightly cold at one point and wished the lights were I little lower but I understand why the weren't."

Pros: "This flight was co-shared by British airways. After our horrible flight from San Diego to London, we decided to upgrade our returning flight from London to San Diego to a economy plus premier. This time the plane seems newer and recently refurbished. The seat can recline more, with lump bar support and nice foot/leg rest. It has a bit more legroom. The cabin is nice and new with large view touchscreen TV for each seat. Gluten free meal was good, I'm just glad they finally boarded the plane with my GF meal (after repeated unsuccessful attempts). The service was great, our BA attendants were polite and attentive."

Pros: "Bulkhead seat Good choice of movies"
Cons: "Seat recline broken. Sarcastic male steward. Terrible food. Contracted Norovirus from the plane. Need to better disinfect between flights."

Pros: "The flight to and from Los Angeles was operated by British Airways and was on one of their Airbus fleet. Boarding was completed efficiently and with ease. I sat on the upper deck and was very comfortable in comparison to other major airlines previously used for this particular flight. The plane was very clean and the crew were outstanding. Nothing appeared to be too much trouble for crew, and they were ready with beverages, including tea and coffee, and snacks throughout the flight. In flight entertainment was good. All in all very pleasant flight to and from the U K."

Pros: "Good customer service, top notch on all aspects. Very attentive staff.."
Cons: "2 hours late to leave but part of wing flap needed to be repaired before flight"

Pros: "the crew were very friendly, well organized. movie selection was great. meals were surprisingly good and plentyful"
Cons: "not enough leg room. and i have to point out that I am a petite 110 lbs, 5'2" woman. as soon as the person in front of me reclined their seat to either sleep or lounge, I had my food tray on my chest and the small tv screen 8 inches away from my nose. Thankfully Im small but the man sitting next to me was rather tall and had to turn into a human pretzel to fit in that seat and space allotted."

Pros: "Courtesy of staff was top notch"
Cons: "Older plane. Entertainment system very dated poor screen quality."

Cons: "No TSA pre check"

Pros: "The service were very good. Just wish the food better selection."
Cons: "The leg room were tight."

Pros: "AA fly to/from Charlotte and if you are lucky you'll get a local NC crew, southern drawl included. The A330's are nice, even without Prem Economy the seating space is decent on the former USAir metal."
Cons: "The USB charge points do not work. Plus, the touch screens for the IFE require a lot of hard tapping on the screen, annoying for the people in the seat on which back the screen is placed."

Pros: "Great flight and nice people"
Cons: "Because the flight was through british airways, extra baggage was $90 much more expensive than Finnair's prices. After paying that before departure to London I recieved an email from British Airways that stated an extra bag for both my flight to London and return flight to San Francisco had been fully paid for. At the airport I was told by British Airways employees that I would have to pay another $90 regardless of what my email said because their official prices are $90 each way not both. I showed them the confirmation I had recieved and all they could say was "that is confusing". There was very little empathy or attempt to help. As a result I was forced to leave the suitcase behind with my acquaintance in London and do an in airport shuffle of all of my belongings. The flight was great but beware emails that may not match up with online info."

Pros: "We ended up being on a BA flight which was fine. Ok service, check in from London much better than USA. In flight entertainment good."
Cons: "Nonchalant crew on the way back, I asked if they had any snacks half way into the flight as I didn't eat dinner, I went to the galley and the head of customer service heard my request, looked at me and just carried on reading his paper leaving a flight attendant to offer me a small bag of pretzels , which she had to search for. Very poor"

Pros: "It was a British Airways flight, plane was large, and felt more roomy than what I'm used to. The service was impeccable."

Cons: "The movies did not play on my screen. I tried to use the screen on the seat next to me and the movies quit in the middle. It was very annoying."

Cons: "I booked this through Finnair and it was a British Airways code share .I was unable to get the record locator for BA and could not check in prior to getting to the airport ."

Pros: "Good service...."

Pros: "Crew were friendly, helpful and efficient Entertainment was very good, especially on outgoing flight"
Cons: "Broken a/c on one flight, sweating buckets No leg room at all on outgoing 747 Disgusting smelly BO passenger on return flight"

Pros: "Crew staff pleasant although did not particularly take the initiative to help customers."
Cons: "Boarding process at Heathrow was chaotic. Could not hear announcements and the response was a large crowd pushing towards an unclear entrance point. The seats are quite small and recline a minimal amount My biggest complaint is that four of us traveling together could not be seated in close proximity to each other, despite making that request over four months before the flight. Extremely frustrating to deal with check-in process as well--because we booked on Finnair, we could not use online system. This was an aggravation considering we were traveling. And--one of our bags was left behind in London. \"

Pros: "The new 777 airplanes were exceptional as well as the splendid airline crew!"

Pros: "I was very pleased with the overall experience on the flight from London to Charlotte. The flight itself was very pleasant, the crew very accommodating, & the food, snacks & beverages very good. The entertainment provided was certainly suitable for my tastes & kept me occupied for the majority of the trip. There was also blackout time provided for sleeping. The seats were a little cramped, but overall I rate my experience as very good."

Pros: "crew were great!"
Cons: "movies offered were poor. a dinosaur (great for kids), and a movie about love (horrible for all). food was yuck."

Cons: "15 hours before the flight, I was locked out from the website to check in and secure seats. I then called British airways to do so and after 15 min of the agent trying to get seats, she told me that there was a shutdown and no passengers were able to do so and everyone had to book seats at airport. When I got to Heathrow, the agent told me that was not true and everyone was able to book online.. Misleading!"

Pros: "The inflight movie selection."
Cons: "The uncomfortable chair."

Pros: "Very relaxing, enjoyable flight. Entertainment was great with many different options to choose from (music, tv, movie, games). The plane was not full and I had the entire row to myself, making the flight that much more comfortable. Awesome crew that was attentive and friendly. Probably one of the best flights I've ever been on. Thanks!"

Pros: "Crew was (as usual on BA flights) friendly, attentive, and personable."
Cons: "Boarding was a bit chaotic. Everyone was all bunched up and you could not get through when your rows were called. Also, when they "boarded by rows" the called rows 23-50+ all at once so that people were all bunched up in the isles of the plane. It really did not help"

Pros: "Traveled BA and it was lovely, as usual."
Cons: "The flight staff on this particular BA flight was not as accommodating and friendly as I am so accustomed to on BA. Perhaps the flight attendant in charge of our seats was having a bad day. Also, the food on our BA flights to and from NYC was not up to scratch and rather bland and ordinary, compared to their usual. that was a huge disappointment."

Cons: "In-flight entertainment was not working. Made and 11hr flight seem light 20 hrs."

Pros: "Friendly flight crew made me feel very welcome . Food and drinks service was excellent, nice choices. Movie selection was vast."

Pros: "Friendly crew"
Cons: "Miserable, ancient entertainment system that had to be restarted 3 times"

Pros: "it was fine"

Pros: "Flight operated by BA; food was excellent, wine was free, crew were friendly."
Cons: "Legroom so cramped its dangerous; worse than on my CRJ connecting flight."

Pros: "The pilot was briefing us about everything There werent much passengers so we were seated in a way where we had space. Great entertainment choices Great food"
Cons: "Notting i can think of"

Cons: "My Finnair flight from London to New York was cancelled due to weather conditions in New York. I understand that. What made me very frustrated and angry is that when I contacted Finnair to reschedule the flight I was told the flight was managed by British Airways and I would have to contact them When I contacted British Airways they said it was a Finnair flight and I had to contact them. I finally had no recourse but to buy another ticket through another airline. I feel that I should be reimbursed for my Finnair ticket from London to New York! I paid for a flight I never took. (The Finnair flight from New York to London was fine.)"

Cons: "First of all, though this was booked as a Finnair flight, Finnair was never part of the process after the booking. We rec'd an email from Kayak saying we could check in 36 hrs early - not so. Even at the 24 hr mark, we were unable to check in via Finnair - had to go to British Airways. Finnair was not represented at either airport - British Airways. On the return, British Airways canceled our flight (2 hrs before takeoff), and we could not get a non-stop flight home. This meant that we had to change terminals, retrieve our bags at the layover, recheck, etc. which of course, added 3 hrs to the original length of the trip. Where's our compensation? We paid for a round trip non-stop flight."

Pros: "Crew politeness"
Cons: "Food is only average and not enough good movies to watch"

Pros: "I made it home safe"
Cons: "Little legroom for such a long flight. Too crowded."

Cons: "Boarding was chaotic. Pre boading not enforced, all passengers boarding at the same."

Pros: "I cannot say enough about how kind, caring and paitent the flight crew was with not only me but others I saw around me. Kudos!!!"

Pros: "Although I booked this as Finnair, it was actually a British Airways flight, as I knew it would be. And it was fine--I don't think Finnair gets much credit, but whatever. I'd actually have liked to travel with someone more exotic!"

Pros: "Staff efficient and kind. Main meals good. Snacks/lunch not as inspired. Entertainment options were varied."
Cons: "Boarding was a bit of a free for all. Seats cramped."

Cons: "experience was awful. Helen Rowena Boysen"

Pros: "The crew was amazing. It was a long flight and they kept bringing us drinks and snacks for 10+ hours."

Cons: "Was not able to check in online on either leg."

Pros: "Arrived on time. Smooth flight."
Cons: "Nothing really."

Pros: "British Airway's Entertainment is better than FinnAir. Smooth flight."
Cons: "Nothing really."

Pros: "Great crew. Lots of refreshments."

Pros: "Services, food, smooth landing."

Pros: "The food and entertainment were good."
Cons: "This flight was operated by British Airways. The flight attendants on this flight were very rude and the plane was not as comfortable as the they Finnair plane."
