Cons: "I just wish they used newer planes on this route but everything else was perfect!"

Pros: "My seat was very comfortable. The inflight entertainment was great. I always love the food on Turkish Airline flights. Check in was easy."
Cons: "The flight was 2 hours late. The attendants were a bit cranky....usually they are great on this flight."

Cons: "Maby beter orhanisarion to printimg thicket fot baggess"

Pros: "It was 8 hours late!!!! There was hundreds of people stranded at the Dhaka airport; elderly kids!!! The airline or the airport had no information on why there was this horrendous delay. No announcement- Nothing. I’ll never take Turkish Airlines again in my life."
Cons: "Some kind of announcement would’ve been helpful. There customer service: hire some people who at least knows and acknowledges that there is a delay."

Pros: "They were more or less running on time and the crew were polite and helpful."
Cons: "Change up the menu every year."

Pros: "The in-flight experience was fine."
Cons: "The crew at check-in & at boarding checked me in to fly to Tel-Aviv (transiting at Istanbul) without any comment on visa or passport at Washington D.C. In Istanbul, I was not allowed to board on the flight to Tel-Aviv. I was not allowed to stay in Istanbul. Crew (Erin Uler) who stopped me from boarding the flight said he would help, but disappeared. Othes kept sending me back and forth between transfer desk and sales desk with inconsistent advice every time. I had no way out, so decided I will fly to the closest European country. This was after I had been back and forth for 7 hours. I had to pay full for flight to Greece. I asked to be sent back to D.C. they could not even work that out. I have a return ticket to fly back to Washington D.C. with Turkish Airline on 1 Jan and they said they will need to re-ticket my paid return flight as well. Turkish airline crew did not would not help me fix my return flight back to D.C. They have asked me to contact the agent ( Kayak). Now I am stuck in Athens, a country I have never visited nor planned to. My tours & accommodation, all paid for in Israel, I have lost. I had a tour fully paid in Israel. I have no ticket to return back to D.C. even though I paid for ticket with cancellation insurance when I bought the ticket. The advice between Turkish crew who checked my passport (official) while I was flying out of D.C. vs the Turkish crew who stopped me from boarding was inconsistent. If I had been stopped in D.C. I wouldn't have had to face the events that followed. Now I have lost my tours, hotel in Israel. I had to pay extra for flight to Athens and I am paying for hotel and sundry in Athens while waiting for flight out. Turkish crew at Istanbul were not only unhelpful but rude and inconsistent. While I was waiting for 8 hours for a firm information, shouting matches between Turkish crew and customers went on at least a dozen times. Inconsistent information from Turkish staff has led me to be currently stuck in Athens. I am waiting for a way back to D.C. There should be a rule that fines an airline if they board people without accurate visa papers and they fail to check it. There should also be a fine to the airline if they stop people from boarding at a transit airport leaving passanger stranded with nowhere to go or return."

Pros: "The service was excellent, staff helpful and understanding."
Cons: "No business class priority boarding, no assistance available with transfer."

Pros: "Leg room was OK"

Pros: "It was all good"

Pros: "Flight itself is very nice. Good service and media selection."
Cons: "Trip from ZAG to IAH Business Class. At ZAG they told me it was fine to take my skateboard onboard. At the Istanbul layover they forced me to pay $160 or else my items wouldn't make it on board. With a business class I still had to pay extra for a carry-on they said it was okay but then they changed their tune. I get it's in a different location but the same company is telling me two different things that ended up costing $160. On top of that, when I finally arrived at IAH they didn't have my skateboards... so I paid $160 for them to lose my boards."

Pros: "Comfortable seats, good food and in flight entertainmen"
Cons: "None"

Pros: "The flight itself was very nice quality again. Crew was very friendly, priority boarding for international business. pod seating was super comfortable."
Cons: "No alcohol beverage service before take off. One of the only airlines that does this. Also flight was delayed again in Istanbul. We were delayed on our layover in, and out of Istanbul. Both times stuck on the tarmac. I see this as a common problem"

Pros: "Flight was on time, relatively clean and the food was quite nice"
Cons: "For a flight leaving at almost 1 am, it's quite annoying to be force fed dinner and prevented to sleep for the first two hours of the flight. Dim the lights and do "on demand" dinner please."

Pros: "Entertainment"
Cons: "Crew are rude. They look always hurry, don't care what passengers need. Food is terrible, there is a menu, but when we ask for food on menu, they said no more, only this one left, so i skipped meal."

Pros: "Great food, comfortable seats. I didn’t go business class, but tbh I think flyin business class this route is a waste."
Cons: "Having to stop over in Bishkek and deplane before going on to Mongolia. Why do we have to go through security again when we’re getting onto the same plane with the same items?"

Pros: "Polite and efficient crew"
Cons: "Crowded conditions. Passengers with too many carry-on items. Passengers removing shoes AND SOCKS for entire flight (unsanitary!). Dirty restrooms."

Cons: "Customer service"

Pros: "Service, updates, smooth flight"
Cons: "Very tight seating in enconomy."

Pros: "Everything. Pleasant crew, great food, clean plane, many entertainment options, movies, music etc. (individual screens)."
Cons: "N/A"

Pros: "Turkish Airlines is a wonderful airline. The service was excellent and the food was delicious and plentiful. They are organized and helpful. On time and smooth flying and landing."
Cons: "Seats are very tight (for those of us who always have to fly economy). Wish there was more legroom."

Pros: "It was great. I told everyone about it."

Pros: "crew, food, entertainment was great. Seats were terrible"
Cons: "seats"

Pros: "Start from online checking, baggage dropped and boarding flight is a hidden tradition of high class hospitality experience. My first time ever to use Turkish airlines succeeded my expectations. food is great, the onboard seat is comfortable and the crews they're wonderful."
Cons: "Quietness and simplicity looks of high quality of crews presentation is a high class professional experience."

Pros: "seats, entertainment"
Cons: "food. only one non-veg option"

Cons: "They was late for boarding The food is bad It's was my bad experience this travel"

Pros: "It was so hot. A nightmare ! I Asked again and to turn it on. They did for few minutes at a time. Very upsetting"
Cons: "It was so hot. A nightmare ! I Asked again and to turn it on. They did for few minutes at a time. Very upsetting"

Pros: "NOTHING"
Cons: "Absolute chaotic experience. Seized all electronic equipment which I anticipated ahead of time and left my iPad home - but they took my camera - which is NOT on the list or a digital device. They had ONE person handling what had to be well over a thousand iPads and laptops. Flight left hours late. NO legroom, Food was horrible and inedible. The entertainment system draped out and locked up 4 hours into a ten hour flight. The WORST flight experience I have had in a very long tie and I have flown all over the world. Will NEVER fly Turkish Air again. STAY AWAY from this airline."

Pros: "Courteous"
Cons: "Nice people"

Pros: "I always enjoy flying with Turkish airlines it is a breeze from check in all the way destination from food to entertainment it all runs so smooth I will fly with u any day so far that is the best"

Pros: "Everyting is good and smooth with no problems at all"
Cons: "Nothing was bad"

Cons: "Na"

Pros: "on time, good boarding"
Cons: "Small space in new planes, water not freely available, limited movie selection, ear plugs are bad"

Pros: "Wonderful food and service and movies."
Cons: "Nothing"

Pros: "Newer plane"
Cons: "Boarding process was very unorganized and slow. People were allowed to act like cattle rushing the gate."

Pros: "I have flown with all big airlines including Lufthansa, BA, Delta, American and others. This flight was by far the best experience I had. They have lovely serving crew so no one actually hesitates to ask or want something. They have helped me and my two toddlers along with 3 other similar families of an incredible amount to make sure they are all comfortable. No wonder that received the best airline of europe award for several years in a row...There was only a 20 minutes delay during take-off and we still arrived home a bit early... Very smooth flight, one that I still cant believe I had with my 2 toddlers. Strongly recommended."

Pros: "Great flight/airline, but boarding was a hot mess!"
Cons: "Overall, we had a great flight and will probably fly with the Turkish Airlines again. But boarding was an absolute mess: the "secure" gate area was tiny and way too small to accommodate all the people on the flight, and the temperature in that area of the terminal was blistering hot. Combined with an organization that was messy, let's just say that all of us were REAL happy when we finally boarded the plane."

Pros: "My mother's luggage was lost and arrived to us ripped the next day and i emailed them yet no compensation has been made and no one has replied to the email."

Pros: "The cabin crew were super friendly, attentive, and accommodating on our flight. Upon boarding the flight, pillows, blankets, and earbuds were awaiting us on our seats. During the flight, the crew handed out Turkish delights, lemon-scented hot towels, and sleep-care bag full of goodies (like ear plugs, slippers, etc.). The entertainment system had quite a selection of music, TV shows, movies, and games! Though it's always uncomfortable sitting on a plane for an international flight, I felt our Economy seats had a little more legroom than most, and there was definitely a lot of stuff to do on the plane if you didn't want to sleep."
Cons: "The second meal I had, eggplant pasta, tasted terrible along with the beans. The only redeeming factor was the yogurt! In addition, the A/C was surprisingly on low, and for the first time, I became hot on the flight - not that I really minded. It was just a different experience. We also took off an hour after we boarded, which I thought was strange."

Cons: "Canceled the outgoing flight"

Pros: "The crew was much nicer and attentive."
Cons: "Food"

Pros: "The attendant at check in was anything but attentive. We asked if the flight was full and she replied with a face gesture that indicated 'no' (it was a 1.50am flight) so we asked if possible to upgrade with points and she totally ignored, spoke in Turkish to 2 other check in colleagues, printed the boarding passes and almost threw them down on the counter without responding on upgrade. We felt too intimidated to ask any more. Also our mileage points for this sector of our travel were not booked to our KrisFlyer accounts so wondering if she did not capture at check in."
Cons: "The cabin was quite warm and unable to adjust any air flow to the seat. Because the flight wasn't full my husband was able to move to a vacant group of seats and lie down so eventually cooled down and got some sleep. Otherwise excellent flight"

Pros: "Service"
Cons: "No applicable"

Pros: "Crew was very attentive, complete punctuality, everything of high quality."
Cons: "no information o.n frequent flier program"

Pros: "Best movie selection, best food. They even came around with pieces of Turkish delight right after we took off. Turkish Air makes it worth flying through Istanbul to get to western Europe!!"

Pros: "service was very good.the seats were very comfortable to sit and sleep.The crew was great."
Cons: "We had ordered Hindu vegetarian meal but food seemed to have been Turkish modification of hindu meal that was not that good"

Pros: "Nothing whatsoever."
Cons: "Worst customer expireince ever. I was making a short trip to visit my very sick mother. Turkish Airline changed my connection time without notifying me such that I had 5 min left for my cooection in stambul. They gave me no other option and blamed this on Kayak and kayak blamed it on the Airline leaving me with no options. I had to stay in Birlin at my own expense. Complaint filed with Turkish airline resulted in nothing. I made several calls for update and only repose I got was we will send an email to the complaint dept. and you will here in 24 hours. This has been going on for over 5 days with no contect, update or resolution. Once back in the US, I plane to file a formal complaint with FAA and more. DO NOT take this airline. They are worst airline I have ever used and will never use it again."

Pros: "Service and food was excellent"
Cons: "Cabin pressure was awful last 30 mins. My ears and teethical were killing me."

Pros: "The crew was fun, informed, and very helpful."
Cons: "The seat, the entertainment, the headphone jack, the food."

Cons: "Flight late more than 3-4 hours on Frankfurt. So upset. I will never and ever try with Frankfurt again. I bought shortest way ticket to pay more money but unfortunately flight late about 3-4 hours. Money trap. I would love to have another free flight or I will post the tickets on facebook, Twitter and etc... To make a terrible flight reputation."

Pros: "Seat was comfortable, food was good."
Cons: "The woman seated next to me was the mother of one of the flight attendants. She had terrible body odor that nearly brought me to vomiting—and this was a 10 hour flight. She was also brought all kinds of amenities from the attendants from the 1st class cabin—not really appropriate."

Pros: "Great service. everything was on time, or early. overall pleasant experience."

Pros: "Great service!"
Cons: "Breakfast and movie selection could have been better"

Pros: "Visa for India was not checked in Denver. Landed in Frankfurt and discovered that the visa was expired. Stuck in Frankfurt for 3 nights until new visa was issued. No babes the entire time I was in Germany. Arrived in Mumbai after paying the $350 US change fee and no bags. Bags finally arrived on Monday at 9AM Without clothes, toiletries and medications for 6 nights. Now I am delayed and will probably have to pay rebuke and fare change to extend my stay here."

Cons: "Worst food ever, and zero entertainment"

Cons: "Limited choice of types of meal - no vegetarian option."

Pros: "The crew was very friendly and polite. The airplane was clean. The boarding was quick and easy. The entertainment was varied and enjoyable."
Cons: "It wasn't an issue on my flight since there were empty seats in my row, but I don't enjoy the spacing provided for personal items on the floor under the seat in front you. For four seats there are three sections; so, you can hope that someone doesn't need any space or else you have to decide how to awkwardly split it up."

Pros: "very professional cabin crew"
Cons: "The overhead bins are way too small, and they ran out of the vegetarian dinner option. There are no longer air controls for each seat, and the plane was quite cold."

Pros: "See above"
Cons: "See above"

Pros: "The best in-flight service I have ever had on the Lufthansa flight from Denver to Munic!"

Cons: "We were charged a rebooking fee by Lufthansa when customs searched luggage causing us to miss connecting flight"

Pros: "Crew worked very hard to accommodate us."
Cons: "Was seated in a section with many noisy infants. I could not sleep or even hear the entertainment system sometimes. Not the airline's fault. People should know better than to travel with infants. I felt sorry for the crew."

Pros: "Lufthansa certainly stands out above ALL American carriers"

Cons: "The crew we had was very impatient and irritated quickly. The flighy attendent name was Jorge. Starting at the beggining of the flight before we took of I asked him about the head phones. One child had one on tye chair and I asked him if its suppose to be on the seat or given later on. He said it will be passed later and then with a patronizing manner he gave another head phone set and said: "I guess we havw an emergency". On the flight, every time he with the food and drinks he just stood there next to me talking over my head with the passenger begind me. Very uncomfortable, especially when it happens 6 or 7 times. When asking what drink we wanted ( the first time), i replied apple and orange juicewith no ice. He replied, with a patronizing manner "this it European company, not American company. Here we don't put ive if you do not ask for it".The incident that bother me the most is one that involved my kids also. My daughter (3 years old) was a bit scared of the flight, tired and did not want to sit on her chair. We tried to keek her on the chair buy she started crying laying down on the floor infront of our seats. Jorge the flight attendant saw her and told me to put her on the seat. Not in a manner I expect out of soneone in the service industry. I told him we are working on it and we will have her on the chair as soon as we can. When I said that he got irritated and a bit aggressive. For no reason the situation became hostile. The flight attendent on the other side (do not know his name). Can over and asked us what we needed amd if we need help. I told the other flight attendant we need 5 minutes and he said OK. After a few minutes she calmed down. Anotger passenger asked Jorge what beer it is and he replied, with contempt, " its German beer, its good"."

Pros: "Pleasant crew."

Pros: "seats were uncomfortable and why dont the armrests go fully up? it made sleeping difficult"

Pros: "Crew, plane was very comfortable, meals good and generous, luggage easy, on time. Overall, outstanding"

Cons: "Before we boarded this plane we arrived at Aer Lingus for a 2 hour layover. The airport only had a snack bar open and an express bar with only drinks. There was cafes upstairs but that was closed off to hundreds of people with a layover between flights. When asked they said it was closed off by escalater and elevator to all of us. They blocked the escalator with a giant gate sign. People waited in line at a snack for over 20 mins for a bite to eat that was express food or a choice of 5 sandwiches that came hot that actually sucked not worth the money at all. People were pissed! I was looking forward to a nice meal for my layover but that definitely did not happen! They only came around once with drinks on a 6 hour flight, then twice for coffe and tea. When I asked for a sprite they said they ran out of things completely"

Pros: "We paid extra for the seats ... it's a good value to get on and off more easily. I liked the way they gave food (for free) and beverage every couple of hours. The pilot communicated well."
Cons: "The entertainment was not that great -- I had trouble filling the time of our overseas flight with movies; which I like to do going east to west to keep up with the time differential. The bathrooms ran out of water in the toilet about 2 hours before we landed so I didn't want to use it. Again, it was an old plane."

Pros: "Overall, the airline is nice with decent entertainment and food"
Cons: "Every time I book with orbitz, even months in advance, I get seated in the last seat of the plane so I am in the toilet"

Pros: "Nothing"
Cons: "Everything. 'Nuff said."

Pros: "The fly from London to new work was very good Very comfortable , there were many empty seats since the Hamburg airport on Sunday had a mayor outage And we were forced to change our fly and stay one more day , the representative on the phone were very helpful! When we contact them to check out fly"
Cons: "We lost a day since we supposed to return on Monday but because the outage we were forced to stay one more day in our hotel at our own expense We had pay for insurance but not sure if was cover at that moment we were tired and frustrated since they block the entry to the airport and we were force to turn around and go back to our hotel witch was hrs away , couldn’t Get nothing near by everything was bucked and all airports around as well The return was very stressful but we enjoy our stay in Germany"

Pros: "Great selection of entertainment."
Cons: "No complimentary free alcoholic drink with your meal on the Aer Lingus Flight."

Pros: "Never made the flight"

Pros: "Great choice of movies and TV shows."
Cons: "The underseat area for storing carryon is SMALLER than on my last trip in Aer Lingus. My simple backpack which has always fit under would not this time."

Pros: "Great seats plenty of leg room"
Cons: "The food... Yikes"

Cons: "The plane interior needed maintenance. The seat pocket in front of me was falling off, and things were tattered"

Cons: "Our flight from LA to Dublin was cancelled day of and the airline put us on another flight. We came to find out that they did not place my fiancee and myself together. We tried talking to the crew but they seemed apathetic and uninterested in helping us. The said the flight was full and everyone checked in but after boarding we found many open seats.. while on the plane I requested help trying to relocate seats so we could sit together and not a single steward would help us. In the end, we finally found seats on our own... Very unhappy throughout the entire journey the quality of service. Never flown with such rude and unaccomadating service personal."

Cons: "Passengers line up to board instead of waiting for their number rows to be called. I ended up boarding later than most and the overhead lockers of the front rows (where I was sitting) were completely full. I had to place my baggage very far back and wait for almost everyone to leave the plane so I could collect it."

Cons: "No free alcohol on an international flight?!?!"

Cons: "Safety briefing crew member & pilot impossible to understand. Very poor diction."

Pros: "On time, newish plane. A very short flight so"
Cons: ". Couldn’t change seat at checkin so couldn’t sit next to husband who was on a separate reservation Boarding is not by seat number, you have to queue up in a long line ."

Pros: "Used the self check-in and an agent offered to help. She was fantastic!"
Cons: "Cattle call boarding.... No system. We prepaid 80 Euro for two carry-on size bags because they were slightly over the 10 kilo limit and then they announced at the gate that if carton bags were over size or weight, they would check the free. Really!!!!"

Pros: "Quick Boarding"
Cons: "Flight was delayed for an hour"

Pros: "Quick flight and made it to Milan early."
Cons: "Only one small beverage (plastic cup's worth) offered, no additional drink even though there was time."

Cons: "Food & not enough water served. The seats had very little leg room on flight from Dublin to Lisbon and people had to maneuver their bodies to get into the seats."

Cons: "Need Fruits, vegetables, salads, fresh fish,"

Cons: "Poor gate service, insufficient information on flight, which was flown by Aer Lingus."

Cons: "Lack of leg room, I know it's the safe in economy on all airlines, but it's tough!"

Cons: "Bags got delayed by a day."

Cons: "Cramped seating. No food or beverage provided without charge."

Cons: "Flight did not include a snack: even a tea cost $3."

Pros: "Most attendants were good, good choices on entertainment"
Cons: "Our attendant was less that helpfully, refused to provide a blanket suggesting that my wife get her own. Locked the lavatorys and had we to ask the good attendant to open for line of folks next to our seats. Never smiled once, maybe her new braces hurt but no excuse. Sorry sound guaility on movies was also poor"

Pros: "Nice, punctual, quick flight!"

Pros: "okay, nothing special"
Cons: "Munich airport had poor signage to find airline to check bags and get boarding passes as we did not have access to print them prior to the flight. Aer Lingus attendant was annoyed that we did not have printed boarding passes and would only give us the one for the first leg with incorrect instructions for getting the second leg boarding pass in Dublin. With the delay finding the counter we almost missed getting through passport control and needed the airport staffer to get us ahead in the line to make the flight. A tense start......."

Cons: "Plane is Dirty. Trash around seat floor and crumbs where remote is. No charging station on seats."

Pros: "had to purchase tea and snacks"

Pros: "Service, flight on time, arrived 30 minutes early"
Cons: "Pram was not waiting at the plane"

Cons: "We didn't like the charge to select seats together"

Pros: "TRANSITION IN BOARDING INTO DUBLIN TO USA LITTLE CONFUSION WORRY ABOUT BOARDING ON TIME"

Cons: "Service on board"

Pros: "Airline cancelled flight at last minute No explanation Stranded us at a subpar hotel for 3 days We got sick there Had to cut short our vacation and return prematurely to the US"
Cons: "Everything See above"

Pros: "I wish more companies would run like Aer Lingus. Flying is usually very unpleasant. Aer Lingus was Great!!"

Pros: "The plane was comfortable, the seats had a decent amount of room, the crew was friendly."
Cons: "The plane was sitting at the gate for at least three hours before we boarded, and then they found a problem to fix. We took off almost an hour late. There wasn't enough barbecue chicken for everyone so they ran out halfway through the flight, so I had no choice but to eat the other option which was really unappealing. When we landed we couldn't go anywhere because it took 20 minutes to get a paramedic on board for another traveler."

Pros: "Friendly staff, food"
Cons: "Nothing"

Pros: "Crew was friendly, food was good"
Cons: "Entertainment was broken in one of our seats, the seats were not comfortable"

Pros: "The seats were comfortable"
Cons: "Everything was ok"

Pros: "Nothing, total stress making us re-check our baggage"
Cons: "British AIrways could have checked our bags through from Denver to Paris....after all it was British Airways to British Airways, but they made us check only to London, retrieve bags carry them to another terminal recheck them for what Simon the BA ticket writer was nothing but pure error by British"

Pros: "The departures and arrivals were on time."

Cons: "Our flight was delayed causing us to take a red eye, missing our connection,long layover, missed our hotel for the night, thripled our time in transit. The worst travel experience I have had."

Pros: "Easy boarding, on-time departure, clean aircraft, friendly crew, decent food, free drinks."

Pros: "Despite having a delay in Denver, we were able to arrive on time. The crew was very friendly in greeting us as we boarded the plane"
Cons: "The boarding process was hampered by too many people putting too much carry on luggage in the overhead bins. Many put things in the overhead bins that could have been put under the seat. It didn’t seem like the crew was paying too much attention to this. In general the crew was pleasant, but there didn’t appear to be much sincerity in the pleasantries."

Pros: "The crew was very friendly. Lots of movie options. I got a voucher due to the delay."
Cons: "The delay was a bit of a bummer and it would have been nice to be compensated with more than a voucher that couldn't be used in LHR because it was in USD. I also would have liked to been told they were still planning on serving dinner despite the midnight departure; I fell asleep because they turned off the cabin lights and I assumed the meals had shifted, but instead I missed out of my dinner. Lastly, I am quite petite and still struggled with legroom."

Pros: "Crew was friendly and helpful, food was ok."
Cons: "The flight was delayed by roughly 5 hours, causing us to miss our connection and have to wait for the next flight. We missed a half day in Rome and instead spent over 8 hours waiting in airports. The seats were also terribly worn and uncomfortable."

Pros: "Orderly boarding and disembarkation."
Cons: "This airline is one of the worst in Europe, for the simple reason of putting short-term profits ahead of decent treatment of the customer. My flight across the Atlantic was 4 hours late, and BA refused to put me on the next available to Prague, even though the lateness forced me to miss the BA flight I have been booked on. Their reason referred to a technicality in the booking procedure, but actually BA has put in place "policies" aimed at their financial advantage, over and above reasonable treatment of the customer. BA's refusal to rebook me cost me a lot of inconvenience (3 hours on the phone, for one thing) plus about $150 (I am taking another route to Prague); BA was then able to sell both my original seat and an extra seat on the next flight from Heathrow to Prague. I will never fly BA again in my life if I can help it."

Pros: "Food and hospitality and staff"
Cons: "We were late 20 minutes and sat in tarmac another 15 minutes. Didn´t allow us enough time to get train, take bus, we had over 500 people lined up for bus, get through TSA, they pulled my suitcase for inspection, but didn´t look at it for 15 minutes until i called a supervisor as my connecting flight was leaving, and in fact, it had left as TSA does this purposefully and maliciously as it apparently happens all the time per ÇBritish Airways who had to reticket us. We had to return to A section another 20 minutes to be reticketed and luckily got on another flight to

Pros: "On board service and amenities"
Cons: "Kayak customer service"

Pros: "I like to fly BA because the crews ( and I assume the maintenance) are top notch"
Cons: "Tired old 747. Needs an upgrade. Packed in like sardines on an old plane that shows it age. Should have flown Norwegian. Major delay caused me to miss my connections though the BA staff were all over it."

Pros: "I arrived safe and sound"
Cons: "Even though I purchased an exit row seat we were packed in like sardines. I know airlines have to make money but that flight was ridiculous. also, the plane was way too warm for much of the flight. Not sure if there was a problem with the air but for these prices...fix it please."

Pros: "They were extremely accommodating."
Cons: "N/A"

Pros: "it was very clean on a board."
Cons: "even water for money"

Pros: "The seat was comfortable and featured the good headrests."
Cons: "Food was inedible so I left it. The sound on the movies was tinny making hearing difficult."

Pros: "The plane wasn't full, so there was an empty seat in-between my aisle and their window, as well as open spots throughout the plane."
Cons: "Plane was delayed several times. Website wasn't clear about what time to show up to the airport. Food was served late and was mediocre."

Pros: "Excellent food and service."

Cons: "Tight seating altho many open at rear so was able to move there"

Pros: "Treated coach like first class."
Cons: "Nothing"

Pros: "Boarding went fast."
Cons: "Too tight, not possible to sleep a little bit."

Pros: "Nothing"
Cons: "I didn’t like that I paid for first and received terrible service in the air and on the ground"

Pros: "Crew were exceptional in service friendliness and attentiveness."

Pros: "Food was delicious and out flight attendant was very helpful. Plane was quiet and the movie options were good."
Cons: "Plane was honestly very dirty. There was a ton of crumbs and gross stuff in th seat back pocket. Which I did not even use because I didn't want any of my things to touch. The overhead lights were covered in dust. So make sure you have some some type of cleaning wipes with you!! I do understand that I was flying economy, but that doesn't mean nothing should be cleaned."

Pros: "Clean plane"

Pros: "Seats were comfortable and staff was very attentive as well as respectful of us when I was sleeping"
Cons: "There was condensation leaking from the ceiling of the cabin. A crew member said this was normal, would have been nice to know this ahead of time to reassure me that for a first-time overseas flier that this is normal."

Pros: "food was good"
Cons: "IFE was not good the equipment is very old and selection is limited"

Pros: "Cabin crew was friendly and accommodating. Flight was on time and landing was excellent."
Cons: "No complaints"

Pros: " Cons: "I was disappointed in the food. On my second flight that day my ticket said I would get a meal but I didn´t."

Pros: "Service, food, safety video"
Cons: "Delayed flight"

Pros: "Fligth attendants of British, Iberia provided excellent and friendly service. Some of London British Airways desk and gates officcers, gave me really poor service."
Cons: "My flight to London was pretty good,. Service was excellent.. But not my transfer to Madrid , I lost my conecttion. On London airport, I was sent back for the gate because I showed up early and they ask me to take care of the screen and wait for the gate #, when they showed the # , I went to the gate and was told my flight had left an hour ago and sent me back walking . I was wearing an orthopedic shoe, due to a toe fracture and i had to walk again all this long distance back to the terminal.!! British airway gave another flight and had to pay $279 dlls for a ticket to Madrid.2 hrs later. My flight was by Iberia and the service. was excelent. I wonder if the insurance , I bought initially will cover something of the $ 279 dlls ticket ? Fligth back to EUA was by AA and service was excellent"

Pros: "Pilot friendly chat at gate"
Cons: "2 hours to offer food through the plane Slow inefficient payment process Bacon roll served with cold Centre - inadequately cooked after 2 attempts"

Cons: "The seats on these flights are poor. As well as being narrow, there are bars on either side that dig in to your sides. My ongoing one hour domestic flight had more comfortable seats. Fod choice poor. Chicken Curry or Cheese/Tomato Lasagna. If I want a vegetarian meal I'll order one beforehand. Give me two meat options. This isn't the first time I've noticed this. Is it cost cutting? Seems like it to me. Not impressed."

Pros: "Very courteous attendants"
Cons: "All good"

Pros: "Very little."
Cons: "Flight was delayed. The seats are uncomfortable and too small for even normal size male. Food was disgusting. Staff were very nice and helpful if asked. I think all the space and comfort were in buisiness and first class. Economy class is still paying for a ticket, make up most of the passengers and deserves better. Getting into a seat was like getting into a straight jacket."

Pros: "The food was better than expected and the crew did everything they could to keep us comfortable"
Cons: "That plane was so gross. The upholstery was stained and frayed. It was also insanely small. Holy cow!"

Cons: "food was not good."

Pros: "Absolutely nothing"
Cons: "Flight was delayed by 2 hours. Then they bumped us out of the seats we had reserved. Made it just in time for our connection. Then they bumped us from that flight. Others were given generous compensation for that bump. However we were given nothing. At least they us we could rest in the BA lounge because I am elderly and disabled and we would have a 9 hour wait. Got to the lounge and we were not listed in the system. So we were denied entrance. We will have have spent 2 nights on a plane and 36 hours instead of one night and 16 hours. Rotten way to depend your 50th anniversary."

Pros: "not much"
Cons: "5.5 hours delay"

Pros: "Just so comfortable and friendly. I'll fly them again next time!"
Cons: "Nothing."

Pros: "I loved the legroom in the emergency seat I had and the service was top notch. The food and food choices was also really nice and the wine served with dinner was great."
Cons: "Overall loved my emergency row seat the only negative for my particular seat was once the rest of my row was filled in and the 2 seats in front of me it made it impossible to get out of the seat and stand up unless I could had the person sitting in front of me get out of his seat."

Pros: "Nothing"
Cons: "Old plane, flight attendants boardering in rude, very poor food (!), de-plane via steps to the tarmac and at least 7 coaches at Heathrow (an aged 747, so it took nearly an hour!)"

Pros: "Everyone was awesome"
Cons: "The staff was awesome"

Pros: "The food was elevated and we were fed twice on our 9 hour flight! The beverage service was also provided often with a good assortment. I loved that there were new release movies available for free. The staff was friendly and available. If I were to do another long flight like that, I would seek out British Airways."
Cons: "Nothing."

Pros: "Wine with dinner."
Cons: "No tv for 9hr flight. Breakfast was awful."

Cons: "We purchased upgrades to an exit row seat because my knee locks up when cooped up for that long. They changed the plane and I understand that happens but they denied our refund request with 7 days deadline to re-request. So now we have to spend valuable vacation time dealing with their incompetency"

Pros: "No turbulence!!!"

Pros: "For economy class it was good seats (bulkhead), the crew were nice, and the food was good."
Cons: "The tiny screens for movies were awful. Worst of all, the horribly loud voices that nearly break eardrums when the crew comes on during the flight was both painful and annoying."

Pros: "Easy and quick boarding. Dinner tasty, but it is hard to cut a fillet steak without hitting the next passenger in the elbow"
Cons: "Only one check-in agent running all desks including bag drop - long wait. 19 year-old 747 had narrow seats in premium economy, uncomfortable and too much body contact with adjacent passengers. Outbound to SFO in an Airbus 380 had sparkling wine pre-take off, hot towels twice, this DEN-LHR flight only had juice or water on offer (crew said "don't serve that on this route") no hot towels, crew's objective seemed to be get around cabin in one go and leave Pax to it Breakfast was abysmal, soft-pretzel roll, no juice or water served, just indifferent coffee"

Cons: "Check in took a very long time. Food was not great. Bathrooms were not cleaned during flight and quite disgusting."

Pros: "The crew were helpful and efficient - it was a short flight so they had very little time to prepare the meal, distribute the meal and prepare the aircraft for landing - but they did."
Cons: "The English announcements by the cabin crew (not the pre-recorded announcements) were difficult to understand at times due to the accent."

Pros: "Flight arrived safely and on time."
Cons: "Luggage was terrible. Forced me to check my 1 small laptop bag despite letting others board with duffel bags, then lost 1 of our actual checked bags in the airport for an hour after our other bag was delivered."

Cons: "Flight was bit chilly, though that’s better than being stuffy"

Pros: "Quick boarding, take off, landing"
Cons: "The announcements were a bit loud and startling"

Cons: "The check in process is terrible and very inefficient."

Pros: "Everything was fine and smooth"

Pros: "The flight went as expected. there were no surprises."
Cons: "?"

Pros: "We almost lost the flight because of long lines at customs and the crew waited for us and let us board the airplane."

Cons: "Ibéria offers a terrible service to its customers"

Cons: "The crew is not nice and rude. The checkin counter didnt allow me to have overweight of 300 grams. Ridiculous. At some areas of the plan the air conditioning doesn't work well"

Cons: "The crew is not nice and rude. The checkin counter didnt allow me to have overweight of 300 grams. Ridiculous. At some areas of the plan the air conditioning doesn't work well"

Pros: "The people"
Cons: "Trafic"

Pros: "Got In ahead of schedule"
Cons: "The boarding process"

Pros: "helpful crew, fast boarding"
Cons: "nothing"

Pros: "Nothing"
Cons: "Delays an chaos"

Cons: "At the checking counter they couldnt find my tickets reservation. Took forever to check in."

Pros: "Price"
Cons: "A cup of water given anywhere else for free was not provided. There was no entertainment. The plane was old and seats very uncomfortable"

Pros: "Everything good litle big later but always is like this..."
Cons: "The latter"

Pros: "Same as the first flight. Great luggage transfer."
Cons: "Middle seat"

Cons: "The food was bad."

Cons: "We have to spend almost one hour because of delay"

Pros: "Hola todos estuvo ecelente"

Pros: "On time, polite, comfortable"

Pros: "Our seats were very comfirtabke"
Cons: "Nothing, it was all great!"

Pros: "Easy boarding On time Very organized"

Cons: "crew... food was awful..."

Pros: "Nothing in particular. Very standard."
Cons: "Before boarding, crew member had each of us throw our carry on luggage through a hole in the wall (no, they didn't help), down a chute (yeah, a slide... not a motorized belt or anything), watching our luggage hit the ones below. No one was below to catch them, and we saw them slamming into each other, some falling on the ground. Highly disturbing!"

Pros: "The boarding process was excellent and efficient. I liked it."
Cons: "There was no free food and no entertainment. That was very disappointing."

Pros: "The flight itself was fine"
Cons: "The agents at check in were rude and unhelpful despite the fact that I was traveling business class. One even tried to tell me what it is like to fly in the US, that it is worse than in Spain."

Cons: "The plane was an Airbus 330. I'm 6'2" and was uncomfortable in the seat for 7 1/2 hours. My knees hit the seat in front, and later the person there reclined to make things even worse. Since I couldn't slouch, my head was far above the seat back. I realize airlines are squeezing space and this trend will continue. It's become an accessibility problem for me."

Cons: "Seats too close together for any kind of comfort level"

Pros: "Nothing"
Cons: "The flight crew only cared about their first class passengers."

Pros: "Landing was perfect"
Cons: "Everything was fine"

Pros: "The flying crew was OK."
Cons: "The company is not good on following schedules, jeopardizing people's duties and responsibilities. Definitely not recommending this company to anyone!"

Pros: "the boarding with 2 kids was super easy."
Cons: "we were not able to get a seat by the bulk head and so could no take advantage of the basinet."

Pros: "great service and nice flight. great pilots and safe trip."

Cons: "Every thing"

Pros: "I like the food and the fact that you provide us with a pillow and blanket"
Cons: "Everyone who was traveling with someone was separated and the Customes right before the bus were extremely rude."

Cons: "arrival and departure times, overall service"

Pros: "Boarding on time."
Cons: "Entertainment- not a good selection of movies. In one of the flights there was no entertainment at all. Food and drinks in that flight was served late. I thought they should serve drinks more frequently."

Pros: "Direct flight. Great service."

Pros: "Upon boarding the flight attendant looked at my seat # and directed to to the correct side of the aircraft. I found this to be very helpful, since on the trip over I was in the wrong side had to bother people to move so I could get to the correct side of the aircraft. Travel can be very stressful, this made boarding quicker and easier."

Pros: "The attendants/crew were kind and efficient"
Cons: "worst seat on the plane. Off center from the isle. Off center tv. drop down table not available due to interference with service carts. Bumped into often by everyone that passes. Next to the bathrooms. 8+ hours of extraordinarily uncomfortable travel. I am 5'4 110 and fit easily in small spaces"

Pros: "The aircraft was clean"

Cons: "I got fever after I boarded the flight. After the lunch/dinner , probably 30 mins after it I asked for Hot water or some hot tea as I was feeling cold. Both the flight attendants told me the service is closed. If this is your hospitality, ba**s to you from next time."

Pros: "My family (four of us) flew FinnAir (Iberia) to Madrid and back and found the service outstanding. The flight crews were top notch, the takeoff and landings were smooth and even, as were both flights, the food was fine, the entertainment was great, and the seats were roomy and comfortable. Overall, a superior experience to any U.S. airline I have ever flown. I would fly them again any time. Five stars."
Cons: "On the return flight from Madrid, we ended up having to board the plane from the tarmac, which was interesting. I can remember decades ago when that was done, but it was a first for us. We checked our luggage, so it was no problem for us, but some passengers had to lug big carry-on suitcases up those staircases. I'm not sure what passengers with disabilities had to do to board. I don't think it was the airline's fault, but it was a little out-of-the ordinary."

Pros: "Got to my destination"
Cons: "Many passengers luggage and mine did not arrive. Had to wait over 8 hours to recieve it."

Pros: "Iberia flight to Madrid"
Cons: "No instructions on how to make connecting flight."

Pros: "Also very nice crew and comfortable plane"
Cons: "We flew Iberia to Madrid, changed planes and continued with Iberia to Boston. While the plane and crew were great, between Madrid andBoston we were severely bitten by bugs - probably a kind of gnat. I was bitten on the face and arms and my wife was bitten on the face and neck. We are still covered. This has caused us much discomfort (including welts) well as cost to ensure these bugs did not come home with us."
