Friendly staff. It was extremely cold in the cabin. I've asked a crew member if they could increase the temperature but there was no change.

Friendly staff. It was extremely cold in the cabin. I've asked a crew member if they could increase the temperature but there was no change.

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!!

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

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

You should not have to pay for WiFi in business class

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.

one of my bags was drenched with fish smelling water and all my new clothes bought at dublin and the 23kg checked in bag were all gone waste with very pungent fish smell and also having stains

We were not allowed to carry a bottle of water onto the 8 hour flight.

Check in -- in business took over 30 mins as there was only one attendant. Boarding was also a mess. The seat was too narrow and was not working properly. Food was very bad and the entertainment very poor. Crew was very polite and helpful, in fairness.

Poor handling of carry on luggage. We had a 8 hour stop in Santiago, are over 70 and, in spite of paying full fare they wanted to send carry on to luggage hold. No empathy. We had to show that several group 4/5 passengers were not sending their carry ons before they finally let Is keep them. Very poor .

reliable, relatively relaxed, with helpful staff in all 8 flights we had on this trip. They are solid even though we did not have special seating or status for the flights.

Airline changed our itinerary several times (3). The second time, we were not aware of it, we landed at 7:24 pm and the flight depart time was 7:40 pm. We were not aware of this change and the flight departed without us, that made us being placed on an even later flight which was also delayed.

The boading process was fine. Had to wait for bus from tarmac to terminal. Had to go through 2 or 3 security checkpoints in Lima to make next connecting flight.

The crew was amazing. The best in the last times. Great group of people.

It’s been some time since I saw the plane and the cabin that old and worn out.

We had 2 delayed LATAM flights in our trip. We were only given one coffee for 5 hours delay. Also when we were boarding the crew wanted to charge us for our allowed carry on luggage. I got a bit angry and they finally didn’t charge anything. Not flying with LATAM again.

The flight from PDX to New York was cancelled, and I got rebooked one day later. Because of this I missed a meeting at my final destination, EZE. I now need to stay longer in Argentina, and was told the tariff difference was $780 plus $150 penalty! I am not using my return ticket, and have purchased a one way ticket EZE-PDX for $606 with another airline. SHAMEFUL

The plane was very old, no power outlets. We also had to wait a long time to board. They kept moving us to different lines before we actually could step foot on the plane. We ended up being delayed an hour but we were never told or informed for any reason. After the meal I asked for a coffee which the flight attendant forgot and I had to ask again. Overall not the worst but not the best experience.

Issues with plane led to multiple gate changes and chaos. Very little communication from the ground crew led to cranky passengers.

It was just okay. They overcharged me for a checked bag because I didn’t know it wasn’t included in the airfare.

i paid accidently for a second bag instead of a golf bag (Eur 40 instead of 50) they would give me credit when i tried to change the second bag from a regular suitcase to a golfbag. The comment was "you made a mistake, your problem"

It was NO entertainment, the screens were not working for anyone. The food was bad in taste, my chicken was hard. The seat in my case didn’t recline. A long and endless flight

Boarding, crew and flight were very smooth and efficient. It was a bit difficult to understand the announcements on board, but it is a minor thing. What was quite bad was the very long time it took to retrieve the luggage at the Frankfurt airport.

Great experience, I just wish airline seats were more comfortable in general.

Onboarding process and crew was excellent and efficient, Information display was great. Keep on the good work and same standard. Nothing to change.

Flights from MADRID to CARACAS and back Seats on the plane were too uncomfortable for a 9 hour trip, especially when the flight was completely full. Crew treated passengers as if we were cattle. Desperate rush to get food served so they could enjoy First class food at the back of the plane... I went twice to the back of the plane (no one answered the flight attendant button) to ask for coffee and was met with a very abrupt response... 'YOU HAVE TO PAY FOR IT'. The only thing staff could think of saying to me was 'la mascarilla senior!'.... In a way I do not blame Air Europa for getting away with this lamentable service, they are one of only two carriers flying between Spain and Venezuela so do not have any competition... I do not think they would dare offer the same service on a flight from London to Los Angeles!

I have loved the flight, very professional and caring staff.

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

Flight was fine - however my husband's checked in case was damaged, and mine still has not arrived

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

I liked the comfort of the plane. It was unexpected from past experiences.

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

Flight was extremely delayed and they didn’t feed us for a 4 hour delay

We had a fantastic crew, super friendly and very helpful but the actual boarding part of it was terrible. You actually felt like we were going to a Third World country to be honest all the way up to the airport and the way it was split up going in all different kinds of directions and no one knew what they were supposed to do was extremely stressful

Very good except my gluten free coeliac meal was not loaded

Crew is always very pleasant. I solely fly one world and always have great experience with BA. Thank you!

I'm flying several times per month in business class. You had the worst food by far from any company I have ever flew with. The Spanish wine was great. I purchased Internet, but it didn't work well for most of the flight.

I liked the crew and boarding, short wait between flight was great. My problem was that the WiFi was not accessible through my phone and on the trip from Britain and Larnaca I didn’t have much entertainment. On my way there I felt that the didn’t give up much food for a 6 hour flight….I didn’t eat much in between flights assuming that they will serve something more substantial than what was served so I was really hungry when I was in Cyprus

Boarding from the SFO lounge is a big improvement. Although the first class dining room inside the lounge is becoming very crowded.

Decent flight, helpful middle seat blocking in business. Boarding staff was polite and helpful. Unfortunately the airport directions to this gate were a mess and the check in staff did not alert us to the confusing signage or any proactive information about the lounge. On board the flight, food and drinks were decent but average. Comparatively, SASs new business catering on this route shines above both in quality and service

we originally had premium economy seats when we booked, but because we were forced to re-book because the first leg of our journey was delayed for several hours, we had to fly economy. Less room, less comfortable.
