Pros: "Everything OK"

Pros: "The flight AMS to MEX was smooth, very helpful personnel on board, we enjoyed a bit more space and the seat seemed a bit more comfortable."
Cons: "Besides the seat relative comfort, it did not recline much at all, i wondered what the extra money (at least $5 or $600) got us. The food, wine/ beer service was same as regular economy, the boarding took place at same time as economy, no drink before take-off if only sparkling water. And the plane was old generation 747 and the entertainment was same vintage: screen was not very bright and the selection of films was poor. No plug to charge electronics. We were disappointed with KLM when comparing with other airline companies offerings when you book in Premium Economy."

Cons: "Flight was delayed, landing at vce took an additional 10 minutes due to no one at the jet way. Luggage service was very slow"

Cons: "Services was pretty weird .. Perse or crew Leader was ok But the assistent Young one was Really bad.. aptitud and not friendly at all."

Pros: "Nice flight ...was comfortable travel ...good food.Thanks"
Cons: "No such things"

Cons: "KLM staff in the Prague airport were some of the rudest humans I have ever met. So incredibly uncaring and outright mean."

Pros: "Friendly in-flight personell"
Cons: "Approx. 1 hour delay, which was not the airline's fault (construction on runways)"

Cons: "Our two hour connection in Paris became 30 minutes because Air France was late in leaving Washington. So our luggage didn't make to to KLM to Amsterdam. My poor rating was because the luggage handling was really poor. Lots of flights from Paris to Amsterdam (almost hourly), but my bag showed up 12 hours later. My wife's bag took 36 hours. And yes, we checked in together. There were lots of confusing messages"

Pros: "The crew were hardworking, responsive, conscientious and friendly"
Cons: "Really poor entertainment choices esp compared to my inbound AirFrance flight. Boarding was pretty disorganized and late."

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

Pros: "Booked extra room seat which gave me good room for seating"

Cons: "The 767 is configured oddly and th business class seats are so narrow it feel like you are sleeping in a coffin"

Pros: "The flight crew was nice. Plane departed/arrived on time."
Cons: "I paid €60 extra to sit in the emergency door seat to get more leg room but once.i was in the plane learned for more leg room I accepted a smaller seat next to a bathroom and no entertainment. I could not store my belongings near me. No power outlet to charge my devices for my own entertainment on a 7 hour flight. Dealing with constant traffic for the bathroom. I sat in the middle seat between two hours other men. It was a constant struggle arm space. After 7hours in the air I could not wait to get off the plane. If I didn't actually pay an extra €60 for the seat I may not feel bad but I feel like I might have been better off without paying for the "upgrade""

Cons: "Headset jack only worked if the headset plug was in EXACTLY the right spot."

Cons: "Bag was lost"

Pros: "The crew came to get me from the arrival gate to get to the departure gate since our plane was delayed. It helped to know that the airline was checking to make sure we made the flight."
Cons: "I did not get my luggage in Nairobi. The delayed flight that was the most likely reason it did not get to the connecting flight to Nairobi."

Pros: "My bagage broke"
Cons: "I paid extra fee for extra bagage which was tv and i paid insurance my tv broke and no one responces for it"

Pros: "The last two times we connected in Amsterdam to Humberside our luggage was delayed. This time it wasn’t. The simple things give the greatest satisfaction"

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

Pros: "The flight attendants could not do enough for you."
Cons: "Business class was pretty empty but again I was not allowed to change my seat selection online. Pathetic check-in."

Pros: "Ground staff at Manchester very helpful"
Cons: "Information on KLM website and flight status said 50 minutes delay and was never updated with the true status. 3 hours before we took off. KLM blamed the fog at Manchester but to be honest most other flights seemed unaffected. Put up in an IBIS hotel and fed substandard food and shitty hotel room with an Aircon unit that clunks into action every 30 seconds keeping me awake. It's external so I can't switch it off. Being given a 10 Euro voucher for food at the airport when most food and a drink will cost you 12 to 15 euros."

Cons: "Flight way delayed 3 hours. Staff gave no information and wouldn't help rebook us onto other flights. They gave us food vouchers 2 minutes before we finally boarded, so we couldn't use them. The food on the plane had spoiled so we were all starving on the flight, and we all missed our connections. Horrible experience and wouldn't fly with KLM again."

Pros: "Professional, welcoming and very friendly crew, well-maintained aircraft, comfortable seat and good food. Keep up the good work, KLM."
Cons: "Not much to comment on here."

Pros: "The crew service is impeccable. Ground services very friendly and professional."
Cons: "The seats are very uncomfortable. The individual screens are simply outdated like you basically will damage your eyes looking at them. No chargers for phones."

Pros: "It was so easy to board and I had no inconvenience. It took 4 minutes from when I said goodbye to my family till when I was at the front of the gate."
Cons: "Nothing! It was all great!"

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."

Cons: "Departure 40 mins late. I took this flight 2 weeks ago and it was also delayed."

Cons: "Toilets are not good"

Cons: "Wheel chair assistance at Heathrow was very very slow it took 2 hours to change gates in Terminal 5"

Cons: "The TV was not working"

Pros: "Professional, nice and pleasant staff, food, timeliness"
Cons: "Small leg room, thinness of Sears such that any small movement from person behind was like a kick to the waste/back, old small entertainment screen, no eye masks"

Pros: "nothing"
Cons: "food / leg room / in-flight entertainment / no wifi / no plugs for electronics - everything was missing and horrible."

Cons: "The flight was late and the info was not shared. The attendants were not helpful and were unkind. The food was served in a strange timing."

Cons: "Small poor pixel quality screen, small movie selection, very avg food."

Pros: "Flight attendants"

Pros: "Boarding, crew and meals were good. Bedding was very nice."
Cons: "Cabin was a tad warm and biz seat was broken. Flight crew was sympathetic."

Pros: "Received a lower than expected upgrade fare for Club World. The new Club World amenities are a big improvement over the older option."
Cons: "BA still needs to improve its Club World seat and update it. It is significantly behind the competition. The seat lacks meaningful storage options and if you don't have a window seat, there is absolutely no privacy."

Pros: "Free movies Comfy seats Good food Attentative and friendly staff As a USA citizen - I would love to put us up as the pennacle, but British Airways puts United and American Airlines to shame."
Cons: "N/A"

Cons: "A one hour connection in london heathrow is near to impossible. I lost my connection i was suppose to be in madrid at 11am and it was suppose to be a 10-11 hours of travel. I wont make it to madrid until 6pm incremeting my travel time to a total of 24 hours for this reason it was and is a POOR and mediocre flight!"

Pros: "it wasn't british airways once i got there - it was aer lingus. this was confusing."

Cons: "Extremely uncomfortable flight with unending turbulence. Seats horrible. Entertainment poor. Crew did not offer enough refreshments. Not a great flight..."

Pros: "Crews were very polite and helpful when I had trouble with my carry on luggage. Cheerful despite the overnight flight. Unfailingly polite when asking people to do things that had already been asked or explained several times."
Cons: "Seat was uncomfortable--something about the contour of the back. Pasta with vegetables was mushy. Not enough movie choices."

Pros: "Seated at front window seat where one can be overlooked, friendly attention and service by attendant was assured and most appreciated. Please thank her!"
Cons: "Seated at front window seat where one can be overlooked, a few times I was overlooked by same other attendant. No kudos for him."

Cons: "There was no rhyme or reason to boarding, except for first class passengers. It was just a free for all. Plane was packed and seats were uncomfortable."

Cons: "Food was awful! In a 7:30 hour flight just one small meal and one bar for breakfast! They ran out of tomato juice the first round and there was only one round of drinks in the whole flight!!"

Cons: "Old plane, no tv screens, seats were god awful"

Pros: "The people were nice."

Pros: "Overall the experience was excellent. However, there was a delay that caused me to miss my connecting flight. Upon asking the crew about my connection, they reassured me that I would be put on the next available flight."

Pros: "Clean plane"
Cons: "Nothing was offered for free to during or even a simple snack what about a sandwich, Huge disappointment"

Pros: "ALL OK."

Pros: "Selection of movies"
Cons: "Time of flight"

Pros: "The crew was polite and helpful."
Cons: "The temperature was extremely warm and the food was terrible."

Pros: "Movies selections were great!"
Cons: "One stewardess in particular was rude to people asking her questions about deplaning. Food options were crappy. Flight was delayed by two hours. They didn't call to notify prior to departure. Thankfully, I noticed early enough and was able to change time of my connection from London to Edinburgh. Otherwise, would have missed it!"

Pros: "Crew, service"
Cons: "Seating was bad, broken springs and uncorfortable back support"

Pros: "The seats are small but otherwise a fine flight."

Cons: "Having paid for a seat 3 months ago, I arrived at the airport to find that I was a standby passenger."

Pros: "Pleasant staff, quiet A380 plane"
Cons: "These seats are so close together you could not even adopt the brace position if they told you to. The seat in front of me was less than one foot away from my face. Not an exaggeration. I measured."

Pros: "Cleanliness, staff, food, staff"
Cons: "@ 6'4" leg room was tight. Please would airlines load from the back to be more efficient?"

Cons: "Very cramped seats; terrible food; was put on Air Lingus instead of BA; missed our connection and Air Lingus was very difficult to work with"

Cons: "Breakfast was pathetic"

Pros: "Nothing went wrong, everything on time"
Cons: "Mediocre service, not what you expect from a premier carrier, I have not flown BA in many years and my how the stands have slipped. Economy was sub par with little to no room, not comfortable for a 7 hour flight."

Pros: "Crew was nice"
Cons: "The arrival, planning and hosting at Heathrow was probably worst I have experienced in 30 years. We had a tight connection, no attempt was made by anyone to prioritize those with less than 45 minute connections. We had one immigration officer for 2 lanes including the fast lane, what is the point of it. After immigration the automatic system did not let us in the boarding area. We were redirected by staff to leave the secure area without any clear explanation of what to do next. When we arrive in the ticketing area, we, several of us, went to try to go through security. That is when we were told we missed the connection. Then we were told to go to B1, after waiting in line we were told to go to zone E for reticketing. At which point I went in standby, only passenger from the group following to Edinburgh, did not make the 2nd flight either. Waited 6 hours at Heathrow..,"

Pros: "Movies. And friendly staff"
Cons: "Decided eating flight delayed. Boarding was bad. This missed connecting flight. Rebooked for flight several hours later and wasted entire day instead of enjoying half a day in Madrid"

Pros: "The flight,from take off to landing & crew was very good."
Cons: "The food served from Washington to London was very good. However,food served from London-Lagos though good but i was surprised that when the cabin crew who served our compartment told me that my choice of lunch was no more available in the plane to served me. Simply, they ran out of chicken and rice when it got to my turn. I had to demand to speak with the manager who came to speak with me & had to go to business class wing to get me a meal to eat. The manager was very understanding & nice.She took good care of me & fulfilled my desire.She made me happy. In conclusion,every flight should always have more than enough food to go round every parssenger in every flight in the future."

Pros: "I've boarded flight half this size in twice the amount of time it took to board this Airbus A388. I enjoyed sitting on the upper deck. It was a night flight to London from DC, so I closed my eyes straight away, and didn't partake in any of the meal or entertainment options available. Flight crew was very nice and personable."

Pros: "Kind and helpful staff, clean plane, generous food and drink service"
Cons: "Very cramped and thin seats, and rather hot temp in the cabin"

Cons: "na"

Pros: "Seats were good, movie selection good. Everyone very nice."
Cons: "No breakfast!! Just grapes or banana and granola bar??"

Pros: "I liked that there was no one in the seat next to me. The seats were large enough. I am 5'9" so that is always important for me."
Cons: "The kid sitting behind me intermittently kicking my chair. I was awoken with 3hrs left to go with a hard kick. But kids what are you gonna do."

Pros: "The pilot communjcated very well and was able to keep passengers calm during the heavy turbulence."
Cons: "I was only allowed ONE free bag for an international flight??? Totally unheard of. This was my first time flying BA and it will certainly be my last. For a 12hr flight, we were only fed ONCE! There was also an hr + delay without prior notification sent via email."

Pros: "Smooth flight, friendly staff, blankets provided!!!"
Cons: "Nothing"

Pros: "Great staff making the best of the economy class conditions"
Cons: "I guess it's nice that seats recline and give a few extra inches, but the rows are way too close, so when seats are reclined, nobody's getting out, nobody's getting up to stretch, and nobody's using the tray table."

Pros: "the seats,leg space"
Cons: "crew should be more involved"

Pros: "Pros..Communication was excellent, we knew our flight was delayed hours in advance so we could prepare, they rerouted our connection so we didn't have to worry about that on arrival, and the onboard crew was excellent and caring. They helped a family to sit together by asking for volunteers to move, and they helped me locate my daughter who had been delayed by a problem with gate check in. The flight was smooth and we all arrived safely."
Cons: "The seats in economy were extremely cramped, there was no legroom and I don't know how tall people could fit in there. There is no way a person could get out of his or her seat to go to the bathroom without making the others in the row stand up and get in the aisle and that's pretty uncomfortable to do on an overnight flight when people are sleeping."

Cons: "Felt cramped in the seats."

Pros: "First time on the huge Airbus. It was fantastic. Romy and comfortable"
Cons: "Reclining of seat back became a bit uncomfortable"

Pros: "The addition of headrests are very good."
Cons: "the seat size, like all other airlines, is small and uncomfortable for 7 hours flight."
