Cons: "Although Ontario only has a few gates for Alaska I still found it strange that they didn't post which gate we would be boarding at until 5 minutes past the scheduled boarding time. Not a big deal but for someone who's not familiar with the airport it could be confusing."

Pros: "The trip was smooth and worry free"
Cons: "Everything was great. As a matter of fact, I shared in a couple of recent conversations how much I like Alaska."

Pros: "Loved the early arrival, the seamless process."

Pros: "Sat in Premium. Early board because of wheel chair. Lots of room. Smooth flight. Arrived early in Seattle. Ta very nice. Took all way to car in parking lot. Cleanliness."
Cons: "TA forgot one of my bags at security..but I didn't miss until almost to departure gate. Had to check my medicine bottle of cough syrup. What a pain. Put into separate basket. Open & swab.

Pros: "Very friendly staff."

Pros: "The short flight was made especially nice with one flight attendant offering to give a free drink for showing Seattle seahawk pride! Either wearing a jersey or showing a picture with seahawk pride. Very friendly and fun! The views were very beautiful also! Love Alaska airlines and LOVE the seahawks!!"

Cons: "The flight was canceled but I received NO notification WHATSOEVER and was not aware until I got to the airport- which was a 2 hour drive away."

Pros: "The flight home from Ontario CA was better than the flight there. The seating was pretty cramped . We got pretzels which was great. Service at this airport was extremely kind and cheerful. It made traveling with a disabled mother much less stressful. Thank you!!"
Cons: "Paying to check our bags when others got theirs checked for free by taking them to the gate wasn't fair. Having my disabled mother have to walk from the ticket counter to some wheelchair waiting area rather than bringing the chair to her started it trip off with stress we didn't need. I even asked if they could bring it to her and they said just go over to the station and wait."

Pros: "Prompt, fast, efficient, and courteous."

Pros: "Nothing g"
Cons: "Plane was delayed....which is fine... but when we finally landed, we parked on the tarmac in the rain after 1230am . Had to walk to the airport in the rain and wind. Older people were having trouble walking the distance, I actually went ahead to get a wheelchair for an older lady that I didn't know because there was no one on the tarmac to assist. Very horrible experience and I fly Alaska often. Never have I ever exited the plane on the tarmac in pdx and when I complained to an Alaska worker, she told me it was normal. I fly to PDX once a month and have never exited directly on the tarmac. I will definitely look for any other airline to fly instead of Alaska from now on. I will even fly spirit airlines....that is how much I will never fly Alaska again."

Pros: "The flight itself excellent. Great service The only problem was when we landed there was a traffic jam and could not get to the gate for 20 minutes."

Pros: "Great crew"
Cons: "Food ok"

Pros: "Great customer service very professional look forward to their services in the future"

Pros: "Easy Access"
Cons: "The All of the business in the Ontario airport were closed at 3pm."

Cons: "Bad: The plane from ONT to SEA was very cold and pretty cramped (compared to economy on JetBlue (PDX to LGB)). I think it was on this plane that the seats tilted back about 2 inches. Sleep was impossible."

"Great service during the pandemic."

"Our favorite flights. Straight shots, with as much comfort as one would expect."

Pros: "Crew was nice"
Cons: "Nothing really"

Pros: "Crew was great!"

Pros: "Check in at the airport- Delta is so friendly and helpful!! Flight crew was wonderful"

Cons: "3 1/2 hr delay"

Pros: "Dinner was great"

Pros: "Crew and service was amazing"
Cons: "Paid $28 for internet and it didn’t work"

Pros: "Cabin crew and entire experience was phenomenal. Cannot recommend Delta more!"
Cons: "Nothing"

Pros: "Crew was amazing"
Cons: "Food could have been better, seat was uncomfortable."

Pros: "Crew, food, flight."
Cons: "Could always use a wider seat. I just hate having my hips touching a stranger for the whole trip."

Cons: "Plane was late taking off. Crew did not provide water when requested. They were busy with beverages that they could sell at a cost."

Cons: "Wonderful"

Cons: "Best option across the pond"

Cons: "Seats hardly recline. Very difficult to sleep in this red eye flight."

Pros: "The crew was amazing"
Cons: "Ran over 2 hours late with no explanation"

Pros: "Some of the crew members talked loudly in the galley all night long. Mostly gossiping and complaining. We had the last seats next to the galley, so it was frustrating to not have quiet and be able to sleep. This was a flight run by Delta for Air France."
Cons: "The food was horrible."

Pros: "Great crew."
Cons: "Seats could be better. But the delays in deicing the plane could have been handled better."

Pros: "Crew was helpful and food was good."

Pros: "Lisa @ the Boston Delta check-in counter is AMAZING! She's super helpful and essentially saved our vacation! Her coworkers say she's the best and I couldn't agree more! Delta is very lucky to have someone like Lisa on their team!"
Cons: "Nothing to complain about! If I really head to be picky maybe the in-flight meals were smaller than I expected. But again, nothing that bothered me"

Cons: "Noise in cabin unable to sleep"

Pros: "Great service. Smooth flight. Funny flight attendants. No issues boarding or deplaning."
Cons: "Food wasn’t great. What’s new?"

Pros: "Got to London on-time (early, actually) and safely. The in flight meal was okay. The leg room in comfort plus was great, the mobile app was awesome, and the staff (check-in, gate, cabin and flight deck) were professional and friendly all around."
Cons: "The leg room was great, but as a broad-shouldered guy, the width of the seat was miserable. Unfortunately, the Delta 767 doesn't offer any upgrade for a wider seat beyond Delta One, and my employer won't spring for that. Too bad there isn't a premium economy option. Also, the entertainment unit in the seat next to mine malfunctioned, which you wouldn't think would impact me that much except that because it was "seeing" touches randomly throughout the flight, the screen would turn on, off, brighter, dimmer, play random stuff, and just generally be as annoying as possible to everyone nearby throughout an overnight flight."

Pros: "The plane left on time if not a bit early."
Cons: "With the exception of 1 really nice flight attendant all the others were extremely moody and not helpful. I didn’t see one of them smile through the whole flight like they were just going through the motions. I’ve worked in jobs where you have to deal with the general public but you have a job to do and must smile and do your best to be helpful. I felt intimidated to even ask for anything like I was wasting their time. I love flying Delta and this was my worst experience yet."

Pros: "The staff"
Cons: "Nothing"

Pros: "Great service throughout. Friendly attendants and easy boarding/deboarding processes. Would fly international with them again in a heart beat."

Pros: "Staff. Beautiful excellent"
Cons: "Need more food"

Pros: "Quick and easy boarding. Quick flight"
Cons: "Audio entertainment quite limited"

Pros: "Staff are nice, and helpful"
Cons: "Take far too long, efficiency is extremely poor, missed flight due to luggages being lost, requested vegetarian meal, when booking, confirmed at gate but didn't have me on the list for special meal. ECONOMY class has nooo room for a long flight...and no entertainment only 3 choices for western."

Pros: "Food good, wine OK"
Cons: "Discomfort bad"

Pros: "Space looked a bit cramped in business class but I was pleasantly surprised at the length of the flat bed and the additional foot well space once I'd reclined the seat."
Cons: "Need to fix the flickering lights in the JFK club lounge, the opposite of relaxing!"

Cons: "Price to get a little more space"

Pros: "Crew was very helpful."
Cons: "Food was terrible and check in can be more organized."

Pros: "I booked via Kayak using Virgin Atlantic shared out to Delta. Check was confusing as both airlines used different flight numbers. When I went to check in with Virgin Atlantic they told me to go to Delta. When I went to Delta they told me to go back to Virgin Atlantic. I wound up checking in with Virgin Atlantic. Everyone was very polite but check in was confusing. Everything else was wonderful. Cutomer service was great from beginning to end."
Cons: "Check in."

Pros: "More seat room than expected for economy tickets. Good service, on time, polite staff"
Cons: "Duty free purchases not waiting for us at boarding like usual. Audio selection on entertainment was v poor"

Pros: "Boarding was easy, flights on time Wi-Fi available (although I didn't use it)"
Cons: "Seats rather crowded in coach, small plane so it was also a bit noisy"

Pros: "Delta has a pretty good entertainment system. Lots of movies to watch and the system works well."
Cons: "Seats are very tight and uncomfortable. The food was horrible. Tasted like a $1 frozen meal that was microwaved til mushy. It was chicken but I couldn't tell you more. And flight attendant helpfully described it as 'chicken'. Breakfast was a cold roll, a piece of cheese and some awful yogurt. This was the most unbearable 8.5 hours of my life."

Pros: "Crew were good, flight on time, free drinks"
Cons: "Nothing"

Pros: "Crew was the best!"
Cons: "I really dislike the snack boxes. Snacks need to be more like a small sandwich or grapes, cheese and nuts. Not all that packaged stuff."

Pros: "Thomas our steward was excellent."

Pros: "The flight was smooth and the food selection was surprising delicious. The crew was very attentive."
Cons: "The leg room was much less than the last time I flew Virgin (booked via Delta) and made for an uncomfortable trip. Could not sleep as a result. If you're tall like me you'll need to book a higher seating category."

Pros: "Everything that British Airways tried to do to help us when Delta didn't want to take ownership for their screwups!"
Cons: "Not only did we miss our Delta connection but when Delta rebooked us on a British Airways flight they refused to help when British Airways could not access our tickets. they kept saying since it was Virigin Atlantic who we originally booked through that VA woulkd have to fix it, even thought Delta was the actual carrier and the ones that did the rebooking onto the British Airways flight"

Pros: "My Delta flight was a code share with Virgin Atlantic. A pleasant flight overall with my first impression being an airline with current popular music playing in the background and flight attendants cheerful. Since I was traveling alone, I opted to not purchase my seat prior to my flight date, instead I chose my aisle seat within 24 hours for free. I checked in my one bag and found out I had pre-checked so my security check went so smooth at the new terminal 2 at LAX. Looking forward to my flight back on June 15."
Cons: "Had a toddler behind me crying and screaming the last 40 minutes of landing into Heathrow because she couldn't sit on her mother's lap and made it quite unbareable for all of us in the vicinity. Wondering if there was an alternative way to handle the situation."

Pros: "Everything was just right"

Pros: "On my ticket it clearly indicate that I am entitled to 2 check in baggage. Delta completely refused to honor this. They said am only entitled 1 piece, and therefore I have to pay for the other luggage. I was forced to borough money from someone at the airport just so that I could board the flight."
Cons: "I am asking that my money be refunded. And next time delta should honor and respect agreements. And be more professional"

Pros: "The amount of movies to watch"
Cons: "Seating not enough room, couldn't use the overhead lights for 7 1/2 hour flight. Ridiculous."

Cons: "The food was supposed to be hot chicken was served cold"

Pros: "The flight itself was fairly quick."
Cons: "We were late by 4hours and they kept changing the times. I wish they would have set it to one time like the other airlines. The seating is uncomfortable and there was no entertainment."

Pros: "Online check in was very good. Liked the ability​ to select free seats ahead of 24hr window. Liked being air side for the whole trip Detroit airport Terminal A was good. Free WiFi 50mb + awesome. Crew were friendly and efficient Will do this trip again."
Cons: "Seat always seem uncomfortable after 3hrs anywhere! And more leg room would always help. Food was OK liked the choice of 3 meals difficult to do quality food for 200+ but keep trying to improve"

Cons: "It was Delta not Virgin"

"Great flight Will go again!"

Pros: "Nice food"

Pros: "The seats were so comfortable"

Pros: "Yes"
Cons: "Nothing. Flight was amazing"

Pros: "The plane size & comfort was excellent. The staff were very friendly"
Cons: "N/A"

Pros: "Great atmosphere, crew was excellent!"
Cons: "I’m 6’5”, so legroom can always be a complaint, but this wasn’t too bad. The plane appeared to be fairly old and didn’t have WiFi. Entertainment also was on an older screen which was navigated by using an old in-seat phone."

Cons: "Keep the temperature at a more reasonable level. Blankets + two layers of clothing was definitely not enough."

Pros: "Flight arrived on time"
Cons: "No food provided "due to a strike the previous day". Not sure why this would impact on providing a sandwich or snack particularly when champagne was still available for first class passengers."

Pros: "very nice crew"
Cons: "my bagfage was lost"

Pros: "Seats super comfy. Ended up with 3 seats to myself that formed a bed for the lap Uk to NZ. Very nice!"

Pros: "Seat was good"
Cons: "Depart on time (1 hour late), hostess put a laptop in the overhead, which fell out and hit me when the bin was opened"

Cons: "We were allowed to choose our seats from SFO to Amsterdam but not for the return flight. I like to be able to choise my seats when I book the flight. Choosing seats 24 hours before is not convenient when traveling for the return trip."

Cons: "The air conditioners fan was bad and they had to fix it in London which took over 40 minutes off travel time...we arrived much later than expected in Lagos"

Pros: "Nothing!"
Cons: "We were told they were holding our flight, we ran 3 terminals and they’d already left."

Pros: "well mannered and attentive crew - good supply of complimentary food/drink - good over all comfort"
Cons: "boarding was running very far behind - considering this is mainly a hub operations carrier - resulted in several passengers missing their connecting flights -"

Cons: "Larger meals."

Pros: "Smooth and faster than expected trip. I felt free to get up and walk around on this long flight. Food was good. I sat in seat with extra leg room for the first time and it was worth it"

Cons: "I booked tickets via Delta, operated by KLM. They lost both of my check in bags in September, and it happened again today for the same scheduled flights. Had 4 hours of layover and KLM still wasn’t able to manage it."

Pros: "The constant smile conferred by flight attendants through the entire flight."
Cons: "The boarding was a bit disorderly. Lanes for zones 3 and 4 were not clearly indicated."

Pros: "NOTHING"
Cons: "Having to change my seat to accommodate a rude belligerent passenger, who had taken my seat, refused to move until spoken to by steward. She then made my flight a nightmare, until I let her sit in my aisle seat. Even then she was not satisfied, she abused me the whole flight damaged the screen so I could not use it until the steward fixed it. Demanded that I except any and all alcohol to give to her to drink. When I am tea total she then continued to abuse me. I asked the steward to move me he just shrugged his shoulders and said there was nowhere else. This is definitely my the worst flight I have experienced."

Pros: "Shirt flight but well catered, boarding was efficient and quick."
Cons: "Not lots of legroom but adequate for an hour long hop. It was cold on board and also had to board via steps from outside"

Pros: "The flight to Gdansk took off and arrived on-time and the staff were professional."
Cons: "The flight to Amsterdam from Gdansk was late and I had to RUN to the connecting gate. 50 minutes is NOT ENOUGH time to go through passport control."

Pros: "Seats were comfortable and there was enough room for hand baggage. I slept during the flight so do not have opinion on entertainment."
Cons: "Not able to charge my digital devices. When serving beverages and food, the same flight attendant missed me a few times. That was annoying but other attendants were very nice."

Pros: "Everything is top notch for an airline company."
Cons: "Nothing.... I enjoyed every moment of the flight."

Pros: "Left ontime and service was excellent."

Pros: "Norhing"
Cons: "They have mabaged to lost my luggage"

Pros: "Good service onboard, good food. On time."

Pros: "Cabin crew were very professional."
Cons: "Aircraft returned to gate due to fault and was delayed for 45 min."

Pros: "The time keeping was very good. We left on time and arrived early on both occasion. Good organisation. Excellent service."
Cons: "Nothing"

Pros: "Airlines issue"
Cons: "Profiling certain customers"

Cons: "They stole my money"

Pros: "Clean airplane, friendly crew, no rush, nice snacks for a short one hour flight. Just generally a positive experience."

Pros: "Entertainment was good, and crew was very nice and accommodating. Flight was very comfortable and smooth."
Cons: "The food was okay, not that great."

Pros: "quick and relaxed"

Pros: "The sandwiches were simple yet just the right touch, on all four flights."

Pros: "staff was fine"
Cons: "old old plane, very uncomfortable. Tiny bad screen made movies pointless"

Pros: "Very little if any."
Cons: "Aircraft was not very clean,the staff seamed quite harsh at times when speaking to customers. The food was really quite poor but it was a short flight to be honest. Overall not as pleasant as the China Southern flights. I would not like to choose them again unless i had to."

Cons: "KLM can't seem to figure out the order of boarding the plane. Should be business - priority - everyone else. Instead they do priority first, and that's usually two-thirds of the passengers. Also, really tired of the fake business class on these flights..."

Pros: "Great food"
Cons: "Sears we're toooo small"

Pros: "The pilot kept us informed periodically during our journey. I liked that we could choose our seating online. The entertainment was good."
Cons: "The plane was dirty, all seats did not have pillows and blankets. Seating was not very comfortable, particularly as there was a box attached to one of the legs of the seat in front of me, making it necessary to move my legs to an uncomfortable angle."

Cons: "Flight delayed by one hour which meant I missed by train at Southampton by 10 minutes and subsequent bus connect home. Next bus would have been 2 hours later so 45 minute walk home from train station. Didn't bother with food offering, put off by that supplied from Hannover to Schiphol."

Pros: "Jet airways flight till mumbai"
Cons: "Poor legspace in Klm flight till Amsterdam"

Cons: "Pet was left behind at vacation destination as pet's reservation (made and confirmed through KLM) was not found at check in. Waiting for Customer Care to help get pet home and take responsibility for situation and getting no response. Very dissapointed, considering law suit."

Pros: "The flight was delayed by 40 minutes initially then a further 20 making it an hour late. Sitting at the gate there was then suddenly a last call to board the flight and a mad rush for everyone to get on. I appreciate that delays happen but the lack of communication ragardinh altered boarding times didn't make the situation any easier"
Cons: "As above"

Pros: "Staff superb. They even surprised us with an exit row and a gift for my partners birthday! Amazing. Samantha and Dennis also took time to come and personally wish him a happy birthday. A lovely touch. This airline runs like clockwork. They are just great. The sandwich and stoop waffle are nice too."
Cons: "There is a bus to the plane, so that takes a bit of extra time but they are very well organized."

Pros: "Flight was efficient enough and staff were friendly."
Cons: "It was delayed quite a bit and more on-time updates would have been appeciated."

Pros: "Free wee cake."
Cons: "Nothing in particular."

Pros: "Professional, friendly service. Punctual, safe flight. Comfortable, spotless airplane."
Cons: "What is there not to like about KLM? I cannot find anything."

Pros: "Speed, crew, and reliablity."
Cons: "Food wasn't good, no entertainment or accessory plug ins, and seats were worn out! Not comfortable at all. Great leg room though."

Pros: "Short, comfortable flight. Nothing special. Got us where we needed to be without incident."
Cons: "Nothing. This is filler text to meet the min. characters."

Pros: "Everything was nice."
Cons: "Nothing to complain about."

Cons: "Finnair are hellbent on trying to sell goods and continuously interrupt the movies with their confounded announcements every 15 minutes very annoying. If i wanted to buy something its in their mag and as a regional flight it should include some form of nourishment other than juice or coffee one off, tight fisted and not a descent selection of food either"

Pros: "On time"
Cons: "Free bags under Corbin"

Pros: "There wasn’t much to like. One of the crew members stood out by being helpful; his colleagues were bureaucratic and disengaged."
Cons: "This was a BA flight. Food in T3 in toronto was a disgrace, and the whole lounge experience was poor. The sleeping arrangements in business class had no privacy; the food onboard was mediocre. The Air CANADA flight on the same route is far better in every respect."

Pros: "I liked the window seat."
Cons: "They didn’t talk much about the landing card."

Pros: "The crew was great!"

Pros: "Speed boarding process."
Cons: "No entertainment system on a 3 hour flight..."

Pros: "Service, staff, food and beverages all excellent"
Cons: "Seat was just a little hard when lying on my side"

Pros: "Arrived ahead of time Crue"
Cons: "Sales on board"

Pros: "I LOVED my stewardist. This man was so incredibly kind to me and the service he gave me had me questioning if it's usually appropriate to tip them. I wish I knew this mans name so I could rave about him but I unfortunately didn't catch it."
Cons: "Let me start out by saying this was my first transcontinental, longer than 2hour flight...I am extremely upset that I paid the extra money to choose my seat and when booking I chose that I wanted a window seat, well I ended up smack in the middle of the plane with a person on each side of me so I wasn't even able to sleep the entire 7 hour 9p-9am flight. Also when I attempted to check in 24hours prior in order to make sure I got a seat id be happy with it said that it wasn't available for my flight so I couldn't check in and I couldn't chose a seat but regardless I still should've gotten the seat I wanted bc of my preferences at booking. Don't pay the extra to ensure your seat it's a total rip off"

Pros: "The crew were lovely, as were the people checking us in at the airport!"
Cons: "We waited 3 hours to fix a water problem on the tarmack and were seated in the middle of a large group of school kids. Would have been happier without those 2 elements."

Pros: "I like the Airbus A330 model's that AA flies from Charlotte on European destinations. They are the former USAir A330's and they are nice both in business and economy. There are no premium economy seats on this version. And Charlotte is an excellent airport to fly from/to."
Cons: "I wish there was a premium economy offering on this plane. The first row of economy is sold as such but is really nothing like prem economy apart from additional legroom."

Pros: "Pretty quick to get on board, entertainment was great, seat comfort was good., wifi and prices were stupidly over priced and slow.,"
Cons: "American Airlines as usual has overly priced non-working wifi on a 10.5 hour trip.. He food was ok at best.."

Pros: "The crew were trying to help and accommodate the bad situation."
Cons: "Couldn't check in online 24 hours ahead. When called Finnair on the phone, they couldn't check us in, told us we have to check in at counter, by then all good seats were taken and I couldn't sit next to my husband, and this is our honeymoon trip. It's a full flight and All upgrades were booked by then so couldn't even upgrade to business class. Requested a gluten free meal, no crew can figure out it that meal was on board (not in system nor on paper list), so at the end no food for me. I have been dying BA for last five years and this had to be the worst BA flight I have taken, absolute chaos at the check in counter and no organization. One BA counter agent Alexa tried to help but it is just too late. I expected more from BA."

Pros: "Direct from San Diego to Heathrow."
Cons: "The seats are very small--and I am a small woman--so the flight felt cramped. The food was just ordinary airline food--little taste. Coffee served essentially black--no offer of milk or cream. Take it or leave it-- Crew helpful if you could flag someone down. Most irritating: could not check in online for some unexplained reason and required to arrive two hours early. BA does no subscribe to TSA so spent time in a line unnecessarily. AND, then the crew arrived over an hour late so the flight left at least an hour late. The crew explained that their downtown bus did not arrive and they could not arrange one. Given the close proximity to the airport, this should have been a 10 minute cab ride."

Cons: "Experienced very rude cabin crew"

Pros: "Overall a great flight."
Cons: "Breakfast not their best meal. No tea or coffee served, very disappointing."

Pros: "Having read horror stories online about booking with Kayak's partner Justfly, I was prepared for the worst (last-minute cancellations, partial refunds, all-around crummy service). Actually, my Finnair flight was great - it was operated by BA, so it was a nice new double-decker Airbus plane. It was maybe 3/4ths full, so I nearly had a row to myself - shoutout to the jerk who decided he was entitled to the aisle seat. The flight was smooth and easy and best of all, it cost a fraction of what the BA price for a one-way from SFO to LHR cost."
Cons: "The food on BA continues to be meh, but what most people don't realize is that ALL airline food is meh, because your tastebuds don't work properly 30k feet in the air (it's a scientific fact)."

Pros: "Travelled on B A Air Bus. I found it to be comfortable compared to previous flights operated by other airlines. Crew was excellent Overall it was a very good experience."
Cons: "The food - well it's airline food - ok but nothing exceptional."

Pros: "My son and I requested gluten free meals when we reserved our tickets. When the meal was being served the crew had NO record of our meals needing to be gluten free. So we had to get one of the meals that was being offered. This was unfortunate and they made no other attempts to rectify the situation. Also, many TV monitors were malfunctioning, including mine which did not have clear sound. It was jumbled and not even clear enough to make out words in a movie or song on the radio channels. Thank you, Emily Snyder"

Pros: "As always, BA did an excellent job with my evening flight from JFK to LHR. They were prompt, efficient and very helpful and although my flight was quite full, we left on time and had no issues in the air. I was very pleased with their service and especially as I paid such a low fare through Finn Air, I can't complain. This was a great option to utilise, rather than paying BA's more expensive fares. I would definitely go through this way again."

Cons: "When I arrived to board my flight I was highly unsatisfied with the excessive charges I received for my luggage that was overweight (only by 7 pounds). I was not only charged an additional $100 for my second checked bag, but I was also charged $200 for the extra weight. As a college student traveling abroad for 6 months, I did not expect to be bombarded with these fees at the beginning of my journey. Due to this experience, I would like to have been notified ahead of time of the expected charges as it made me uneasy before a long flight."

Cons: "There was a very poor selection of movies to watch:( Last tim ei flew AA, and there was an absolutely huge choice . . . Would love to see that improved . . I think you have to cater for all tastes . . . and that definitely was not the case on my flight"

Cons: "For an international flight I have never seen such small seats, the entertainment was awful. My tv was in black and white. I didn't even want to try the food as looked bad."

Pros: "For once the seats have enough space. Airlines think we are cattle and that they can pack as much as possible every airplane. For once I was glad to have a confortable experience."

Cons: "Our bag was not checked through to our final destination and was delivered a day later."

Pros: "Entertainment choices were good."
Cons: "The flight attendants were noisy, walking back and forth, so it was hard to rest, more like stomping. Was not pleased with flight attendant who served me, was kinda cocky and not friendly, which spoiled the customer service experience. Not enough leg room, cramped. Wish they had decaf tea. Other than that we arrived safely, so I'm very appreciative."

Pros: "Good leg room."
Cons: "I paid an extra $90 to pick this seat. On the website it looked like an exit row seat with lots of room. However I couldn't really move out of my seat without climbing over others. It was a waste of $90."

Pros: "Seats were comfortable with plenty of room."
Cons: "Plane was broken and we had to wait 3 1/2 hours to get a new plane. Crew kept awkwardly mentioning during every announcement that the delay wasn't their fault... My husband's entertainment screen was broken and flickering so much that all shows/films were completely unwatchable. My screen began flickering 1/2way through a film."

Pros: "The entertainment and service was the only plus on this flight."
Cons: "When I booked my ticket a month in advance, British Airways was going to charge me extra for trying to book my seating in advance. They told me it would be free if I called 24hrs before the flight. I called 24hrs before and they told me they could not book my seats because the airport owned the seating. My first flight was with American Airlines, they gave me a boarding pass, however for my leg with British Airways, I had to go get ANOTHER boarding pass to board the flight. This airline was very inconvenient and I felt scammed booking with them. I would not recommend this airline to anyone!"

Cons: "Trying to get through airport security was an unorganized clown show with them herding groups of passengers back and forth between airport terminals resulting in many people almost missing their flights because the lines just weren't moving. Once on the airplane, the international flight had TVs in the ceiling in the row playing one in-flight movie (what is this 1995?). American is such a terrible airline. The old US airways, Lufthansa, and British Airways, are way better international flights every time I've flown with them. Personal entertainment at your seat for each flight (i thought this was standard on all international flights in the past like 10 years) and more food and drinks throughout the flight."

Pros: "Good service"
Cons: "Ancient aircraft."

Pros: "British Airways has greatly improved their customer service, the flight attendants (usually a bit gruff) were instead very kind and helpful to myself and all the passengers I saw them interact with. It really makes the flight experience better."

Pros: "Maybe they should call these flights "Byzantine Airways". Finnair doesn't fly Boston to London, so my Finnair flight was on British Airways, but I did it that way because BA wanted more money that day. As a flight, it was OK. I don't think I have much to say about Finnair."

Pros: "Despite the turbulence the pilot did his best and we had as solid of a ride as possible. Seats were very comfortable and flight was on time, couldn't ask for anything more!"

Cons: "There was a terrible smell; food and drinks were served two hours after the flight started, it was dirty, cold and cramped. The whole experience was traumatising!"

Pros: "The configuration of the seats are really awkward. Seems very interesting at a glance, but not so nice when you have to sit in it for 10 hours. The business class seats are very narrow. I'm pretty petite so it was okay for me, but I think an average or bigger than average person would have a hard time turning at all while the seat is in lie flat position. I had a window seat which gives you more privacy as long as you have the divider up between you and the passenger next to you. You are really arm length away from each other though. And! You can't have the divider down the entire time because they serve your meals by passing it over to you across your neighbor through the divider. The divider is also required to be down during taxi, take off and landing. So, I'd imagine it to be very awkward if you're sitting next to a total stranger. You also have to straddle over someone's legs if you want to get out of your seat to the bathroom if you have window seats."

Cons: "I booked the finnair flight because it was direct and charged $60 for additional bags to check in. For me this was really important since I was moving countries so I needed to check in multiple bags. But since this was in partnership with British Airways, I was charged $90 instead of $30. This was not mentioned or made clear before I made my purchase, if i buy a finnair flight then I should be charged finnair prices on baggage. If not, this should have been made clear before hand so I could have weighed my flight options. I hope you are able to provide a resolution."

Pros: "Nothing."
Cons: "The upgrade to World Traveler Plus was $330.00 and worthless. They assured me Business Class food service. NOT TRUE. You get the usual coach class prison-type food. Non-existent flight crew service (I got one mini can of Coke the entire flight). Cramped seat next to noisy bathroom. Whole experience was bad."

Pros: "Good food - two meals at just the right time."
Cons: "I regularly fly between Chicago and London and dread having to get on AA90. The planes are ridiculously old with barely any legroom and no seat-back entertainment. On this occasion, my friend sitting next to me, who is 5'10" had his knees right up against the seat in front. When the passengers in front reclined it was almost impossible to get comfortable. There is no seat-back entertainment. For some this may not be a big deal, what with iPads and other devices, but it speaks to AA's failure to consider it's customers comfort and ease on long-haul flights."

Cons: "When I got to Phl I missed my connection to London. No one seemed to care that I needed to be in England by the 18th. They kept retorting me to arrive in England on the 19th. I told them multiple times Id be flexible and go to any city in the UK just for them to get me there on the 18th. The First person I talked to said it was impossible. So I called again and talked to another person and all of a sudden it was possible. The worst part was they sent me to Boston after that I didn't get to Boston until 1:50 am and they did not compensate with hotel or anything while my flight to London was not until 8:00 am the next morning. So I spent the night in the airport. Oh and then when I finally got to London, my bag is lost and they told me I'd have it by tomorrow and I still do not have my bag and have called and they said they can't tell me anything."

Pros: "Flight attendants were very helpful and joyful. Food wasn't too bad for airplane food! :-)"
Cons: "I find it appalling that there is a charge for seat selection. Please add 10 cents to the price of a ticket and do away with the seat charge. It would buy you loyality."

Pros: "Crew were friendly and professional."
Cons: "Entertainment system had a few issues."

Pros: "Very friendly and helpful cabin crew. Excellent boarding procedures. The food wasn't awful. Everyone seemed relaxed and upbeat...maybe because the holidays are approaching."
Cons: "The rolls were ice cold, and the butter was not real butter. My husband found the seats cramped, and little foot room. I'm 5'2" and they were ok for me. The child behind me screamed and then projectile vomited for the last half hour of the flight, which can't be laid at BS's door. Many people were still on their cell phones and laptops during the whole takeoff, despite multiple announcements. I would have kicked them off."

Pros: "direct flight"
Cons: "There was a lack of air and no possibility for individual airing your seat, during our flight we had to stand in the back because we were almost passing out of overheating 30 Celsius plus heat in our row. We asked for a cooler temperature and only the last 20 minutes it started cooling but then to ice cold. My audio was not working properly, at max it was still unclear. We have had better flight experiences."

Pros: "Very friendly plenty of room on a 90% full flight."
Cons: "Wished they had offered water during the flight in addition to two times drinks service was offered"

Pros: "The 10 1/2 hour flight ended up only taking less than 9 hours since we had the wind in our favor. I loved all of the free movie selections and the service was wonderful. Great experience."
Cons: "The food."

Pros: "Nothing"
Cons: "Tiny seats. Wouldn't let me pay for an upgrade. Last time I ever use kayak"

Pros: "Great flight"
Cons: "N/A"

Pros: "Nice new plane"
Cons: "Seats too narrow"

"Poor communication from boarding staff, airport staff not a clue. Communication on board was un decipherable and airline lost baggage."

"Could not hear announcements from staff. Luggage in hold was delayed on both legs of trip."

Cons: "There was no amenities pack given in Premium economy. The food was ok. It would have been nice to have been offered another bread roll. Seat comfort was fine, but I kept getting hit by the separating curtain as the flight attendants went back and forth from economy."

Pros: "It was a decent train ride."
Cons: "Stating it’s a train from the beginning and not having to go from one train station to another."

Pros: "Crew were very good."
Cons: "No vegan food available."

Pros: "n/a"
Cons: "The conditions were very cramped. The entertainment system was quite old and had very little selection. My entertainment system actually stopped working all together. I called for assistance from my seat a couple of times, but nobody came."

Pros: "Despite being a short flight, they gave food"
Cons: "Nothing. All ok"

Pros: "Nice and attentive crew."
Cons: "Seats not comfortable in premier economy."

Cons: "They made me check my carryon rolly which is allowed on every other plane in the world, which meant going all the way back into a chaos of hundreds of people to check in. Because I had a connecting flight to New York in London, the check in caused many problems...and everything inside soaking wet"

Cons: "This was one of the worst flights I’ve been on. Both planes were downright filthy. The flight from Dallas to Barcelona had several broken toilets. Flight from Paris to Barcelona boarded and once everyone was on board, they told us that we would be sitting there for 2 hours before leaving."

Cons: "Tell me i would misst the next flight and that my beg will not go to the final airport."

Pros: "Boarding procedures and crew were top. Wines and beverages excellent and even in super economy water was served several times"
Cons: "The food could have been much better, should consider doing everything organic. As it was, the chicken in the meal was awful, the dessert terrible. The rice in the salad hard, almost uncooked. The only good quality food was the bread and the cheese"

Pros: "The whole crew is so kind"
Cons: "Delta made my whole first flying experience the best."

Pros: "I'm not Hindu, but I requested Hindu Vegetarian meal. It was very tasty and enjoyable."
Cons: "Seats were not comfortable, even in Comfort + seating isle."

Pros: "Air. France usual"
Cons: "No lights working on plane. Couldn't read or do work WiFi wasn't working either"

Cons: "There was no entertainment and the food could be better"

Pros: "Flight was delayed 4 hours with no explanation"
Cons: "Asked for wheel chair assistance and was not met in Paris. Had difficulty and barely made my flight. A gentleman who worked at airport assisted me"

Pros: "Crew was very nice. Food was good and tasty."
Cons: "Plane seemed a little worn, which surprised me since it was an A380. Not that old. I had purchased an upgrade to a seat with more legroom, only to find out there was no USB plug for charging my phone. All standard seats have them. Would have been nice to be warned about that."

Pros: "Food was ok."
Cons: "Very little room in economy class. For a 6'1" person, it's impossible to get comfortable."

Pros: "FA kept bumping into my seat waking me up"
Cons: "Return the 777 to 9 across"

Pros: "The crew were polite and friendly"
Cons: "Everything was incredibly poor. Flight was delayed, entertainment was outdated and the airport staff were rude."

Pros: "The entertainment has great selection. The crews were much friendier than the flight from SFO to Paris."
Cons: "The seat padding is rather thin."

Pros: "Just a routine flight but done with perfect execution."
Cons: "Nothing."

Pros: "Staff was so helpful and attentive to our needs.Providing service with a smile."

Pros: "Great service"

Pros: "Flight attendants were very nice"
Cons: "Didn’t have the meal I ordered Got in 30 min early but no gate for us. We waited over 80min on tarmac to deplane I paid extra for an exit seat but there was no indication when I did that there would be walls for armrests and that made it very uncomfortable for me"

Cons: "Plane left more than 40 minutes late with no explanation or apology."

Pros: "The crew and flight was faultless"
Cons: "We were not advised of a flight number change or checking in location change. This could have resulted in us missing our flight."

Pros: "Easy, fast, comfortable, no hassles"

Pros: "The inflight service"
Cons: "The 3 hours delay"

Pros: "Love the flight attendant, loads of food couldn’t take it anymore. Professionalism at its peak."
Cons: "NA"

Pros: "This is what happens when you get roped in by a low price."
Cons: "Disorganization which led to not being able to pre-purchase baggage. Then bad info at airport which led to multiple trips through security trying to make weight on a bag that should have been checked but was told didn't need to. Ended up missing flight, having to rebook at full fare and no one knows where the bag that was checked is. STAY AWAY!"

Pros: "Hospitality of the flight attendants"
Cons: "Toilets could hv been cleaned more often"

Pros: "Flight was only 50% full. Room to spread out."
Cons: "Leg room cramp. Flight arrived late as a result missed connection home."

Pros: "General air of professionalism is reassuring"
Cons: "Food, crew appear rushed"

Cons: "Disappointed to get delayed due to control tower issues at CdG. Landed more than 30 mins late in London"

Pros: "Being able to have my meal at the airport before my flight so that I could sleep in comfort."

Pros: "Premium Economy on AF Boeing 777 on this route is not "a little less than Business", but rather "a little more than Economy". Seats, in a 2-4-2 configuration, are hard but OK, as well as the pitch. Good screens and entertainment."
Cons: "With the main meal, AF serves only "ordinary wine", This looks and tastes cheap. On the same route and class, Vietnam Airlines serves premium wines, a nice touch that would not cost fortunes to AF! Also, the "Asian" choice for the main course did not look and taste like the real thing."

Cons: "The leg-space is very narrow The chair is very tiring No entertainment at all Food was tasteless But most surprising was that we were on stand by for our connecting flight. Though we bought the tickets months ago and we got our luggage checked in all the way to the final destination."

Pros: "Boarding was very efficient"
Cons: "Losing my luggage after checking it at the gate when volunteers were needed."

Pros: "Great food, pleasant crew."
Cons: "Comfort economy okis seats are wide, with good legroom, but did not recline and hard as a rock. Entertainment system hard to use, finding movies very tedious."

Pros: "Crew was great"
Cons: "Not enough food"

Pros: "The flight was good overall. Friendly crew good attention."
Cons: "There was a delay due to technical dificulties in previous flight. This caused a delay in take off and no AC while waiting in the plane for 40 minutes."

Pros: "I like that they still feed you and provide alcohol for free, even on a 40 min flight (unlike BA)."
Cons: "At one point during the flight I took a video out of my window with my camera, a member of the cabin crew barked at me in French. In bewilderment I asked her in English to repeat herself and she sarcastically repeated what she had said, in French, I asked for her to speak in English (which she had done to me previously on this Paris to London flight) yet again she scolded me in French. I was left absolutely none the wiser and it left a bad taste in my mouth."

Pros: "Good food. Although no Cappucino as in AF from Sanfransisco to Paris."
Cons: "No entertainment at al. Specifically, I could not lean my seat b/c of a mom with a baby behind me..."

Pros: "The crew was friendly."
Cons: "One of the engine was smoking just as we took off. This should have been checked beforehand that it was working correctly. The pilot missed the first landing, was going too fast and had to turn around. We circled the London eye 3 times. When we were actually landing it was extremely bumpy and on the way down the plane was tilting back and forth a lot. They were going too fast when we landed as well, I have never been in a plane that has landed so poorly, and I have travelled a lot and used many different airlines. It was worse than any budget airline I've been on. As we were driving back to the terminal, the pilot stopped short for some reason. Things were not explained clearly. I will not be flying with airfrance again and will be sure to spread the word of this awful experience."

Pros: "Boarded 45 minutes late, and then sat in the plane for another two hours before take off due to a problem with the lie computer. Would have been better to spend that time in the terminal and given credits to buy food, etc. My seat was a regular seat (non exit) and the seat did not recline properly, the USB drive was broken, overall the plane felt unmaintained. The crew was friendly and food was good but I felt not enough was done to accommodate the extra hours we had to wait on the plane."

Pros: "Spacious cabin, clean and bright. Attentive crew offering snacks and a drink for an hour flight."
Cons: "Although incoming plane arrived late, flight home arrived 20 minutes early."

Pros: "The plane is roomy and bright"
Cons: "N/A"

Pros: "Boarding and such was straightforward and easy"
Cons: "Everything is uncomfortable"
