The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

The flight was excellent, the crew was super friendly. The only complaint I have is, 3 of my zipper handles were broken and there were 2 massive scratches on the back of my bag

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

Empty seats next to me - wish it had been for a longer flight!!

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

The plane. Airbus A330-200. Comfortable for a 7-hour flight. Seats seemed to have more legroom. I was in row 17. Flight was operated by Delta but was better than expected.

I requested wheel chair assistance , it was confirmed via email that inwoood get it but I didn’t get it . The last leg of my trip to Nigeria was the worst.

One of their staff was so rude with discriminative. Such a reputed airline shouldn't hire such kind of arrogant attendants.

It was a really good experience. Food, snacks, and beverages were good. Flight entertainment was also a good one.

Everything was wonderful, with the exception of boarding a bus to go to our gate. Seems odd, that on both the arrival and departure from Paris we had to drag our bags down stairs, get on a bus to do the next step.

The check-in at the airport was smooth and helpful. There was a delay due to some issue. The good regular but the staff very attentive.

Air France removed our luggage from the plane before it took off, seemingly intentionally, didn't notify us until after we reported it missing at SFO, and is giving us no updates on when, or whether, they will deliver it.

The flight crew was exceptionally friendly and helpful. Also the seats were comfortable and roomier than many other airlines.

The plane's pilots, including the captain himself, thanked me for the flight. I know it's just marketing, but it was really nice to see these people. It's a great idea. Airplane food is never "good," but the entire crew and flight organization were top-notch. I really liked Delta, and I think I've traveled all over the world, and that was something new for me. Maybe even the old planes, the B767, but next time I have a choice, Delta will be my first choice. Thank you, a satisfied passenger :)

The plane was old Only 3 bathrooms available for economy The entertainment was old and the selection was poor

They lost my baggage and I still have not got it back. Disgrace

Food could have been better especially the breakfast. Overall it was a good flight

I have used Air France and KLM many times it will help if they change their menu's feel like it's been the same for years!!!, Especially the breakfast. Overall the flight was good and enjoyable.

Horrible seat at the back. Crew was very kind. Packed plane. Wordy pilot bragging about Iberia being punctual when many of us came from Alicante flight that was delayed an hour and many lost connection and we lost our luggage. Still waiting for it

The boarding procedure got confusing because they wanted to weigh everyone’s carry-on. Apparently mine was 3 1/2 kg over their limit. I didn’t know they had a limit. And at the check-in desk, nothing was said about this. They wanted me to check the carry-on at no charge and that would have been fine except then they told me at my connection in London I would have to go outside to baggage claim retrieve my bag, and then recheck it. In other words, they could not check it to my final destination, only to London. I told him this was unacceptable so after a few minutes of discussion, they came back and said that my bag would be OK to carry on the plane. It seems that if you have a connection then the weight is not as important. Then when I actually went to board the boarding agent said I needed a tag indicating that my bag had been weighed, even though she had just five minutes ago talked to the same person who cleared me. Lots of confusion seems like a very bad process. They need to improve this.

My flight being automatically moved messed up my travel plans, and I had to quickly find an alternative mode of transportation. I couldn’t get a refund from any of the companies involved. Kayak, Ibiza, or Vueling. I am still unsure of how to settle my concern.

I've taken British Airways before and it has been great. On this trip to Spain and Portugal we had two BA flights. On both flights we were taken by bus from the terminal out to the plane on the tarmac. There were many older folks on these flights, and to ask people in their 70s to lug their carry-on and personal items up the long mobile staircase to the plane entrance, is very disturbing. I won't be taking British Airways in the future. Many people on these flights were very unhappy.

The food on the flight was of marginal quality. Small bits of chicken, instant mashed potatoes and some carrots. The rolls were very dry, nearly inedible. The seats were quite small and didn’t allow for any shifting of position during the flight. There was limited leg room.0

Terrible customer service. I booked business class and the counter agent didn’t bother asking me about any choice or preferred seat, basically assigned me that last seat and couldn’t even answer if it was a business class seat. Also iberia lost my suitcase on my flight from JFK to MAD with the layover in BCN. Useless customer service at the counter. Thank goodness I happened to check the baggage claim area of the next flight in…there it was.

It was fortunate that the flight arrived in London in accordance with schedule, and the luggage was promptly transferred to the luggage carousel. However, I find it concerning that even minor issues in economy cabins are prevalent within the industry. American Airlines, in particular, appears to have the least legroom and feels more crowded due to the proximity of neighboring passengers. Additionally, the crew’s adherence to protocol is inconsistent. While they may enforce certain rules set by the FAA on a select few individuals, they often overlook numerous violations, such as failing to reset seat recline during landing.

Easy and organized getting in and out of the flight

Chair is very high. Your feet cannot touch the ground for 8 hours flight. It was a nightmare. Food was bad.

Paid for my seat 4 months ago. Did not pay the extra for specific seat assignment ( never have and never was a problem). Could not electronically check in (found out it was due to overbooking and that unassigned seats get bumped first - never happened to me before). Luckily, did make the flight. Very stressful - would have been extremely disruptive for my travel plans. UK Visa - never notified by Kayak or BA that a visa was required. Had to spend 15 minutes to download and complete app at the flight counter and pay $25, and was told they would let me know in 3 days if I would get it (flight landing in 10 hours from when I completed app). Luckily, visa was approved before landing. Unnecessary stress created here. Food - main meal, curry chicken barely palatable with unrecognizable vegetable. Desert cup, cheesecake, also barely palatable. Salad cup was good. Small water offered only 3 times (before main meal, at main meal, at morning snack) - not nearly enough for long flight.

Boarding was seamless, crew were great. Less disruptions on the night flight would have improved the experience and turning off lights earlier.

Worst customer service I've ever experienced on a flight. They downgraded my seat without giving me any other options, then sat in a seat with an arched back for 10 hours. I was not able to get ahold of any customer service representatives to understand what alternatives I might have, or how they will be handling a refund for the difference in fares between business and premium economy that I was downgraded to.

British airways needs to improve their luggage handling process and communications. The luggage was lost/left in UK. But, this was not communicated to me as a traveler and because of the wait at the carousel in Seattle (we have to go through customs and immigration on arrival to US) I missed the connecting flight and had to be rebooked. No one informed me that the luggage wasn't there, and there was no one there at the carousel to check with or help me get through security faster. I wasn't the only one- there were a lot of people waiting for luggage that didn't arrive.

My bags were lost. I waited in a line for 5 hours after I landed and got no resolution to the issue.

Easily one of the best flights I’ve ever taken. Worth it to upgrade slightly. Crew was phenomenal. Just wish the man sat next to me kept his shoes on. There should be a rule about that. But I wish I could take every flight with BA.

Poor experience at Bengaluru Airport. Slow check-in process. Boarding calls were unclear and by number (no clarification given for priority groups) and were caught in wrong queue with infant based on what was written on ticket. Aircraft seat was not comfortable. Slow initial service for flight at 03:00 where most passengers wanted to sleep - did not seem right to be serving meal after takeoff. Poor quality breakfast in morning, not offered any tea/coffee alongside Only saving grace was that this was a night flight and the plane had free high-speed Starlink wifi.

Great flight, great crew, decent food. Premium Economy was very comfortable. I compare this flight to the one we took on BA from DC to London: Like a different airline. The food was atrocious, the crew aloof, and the cabin not as comfortable. Based on that first flight we said we'd avoid BA, but the return trip changed our minds.

delayed more than an hour with very poor boarding and service

A/C temp. was way too cold during the flight.

I didn't like the food, and it wasn't as good as all other business class that I'm using
