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 lead, Katherine, took care of me in business class and provided exceptional service. She was warm, welcoming, bubbly and proactively accommodating as well as confident, professional, competent and clearly respected by the pilots. Just what I needed on my 17th and final hour of flight time traveling home from a business trip to India.

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

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.

Seats actually fit a human! Snack options were a bit lame but that’s ok

Honestly first time flying with delta and it was pretty good. All the process very smooth and crew was always nice and attentive.

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 .

I couldn't travel, now I can't get a refund and to change the date I have to pay an absurd fine.

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.

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.

Really good other than the seat assignment, stuck in the last rows with a tight connection

British airways was horrible. Our flights were affected by the wildfires and British airways told us they would be able to change our flights but it would cost us 1700$ to switch. We ended up finding a regional carrier to fly us out for 500 total. I was not impressed.

No frills flight poor leg room and plane was 30 min late

Comfort in premium economy is worth it for long hauls especially on the 787-9P Dreamliner with the modern updates. The food was okay. All 4 of us selected the same meal, 2 of us had very dry hard to cut chicken, the other 2 were tender and good. The sides/salad/dessert all very good as far as airline food goes. Crew were very attentive. Will be hard to ever go back to regular economy!

Getting to Scotland with no luggage (no medicine, no clothes and no club) on golf trip very disappointed

Poor... food was horrible, boarding very slow, service on board mediocre

Crew was rude, almost 6 hour flight after horrific customs re entry line and near flight miss (unable to bug airport food) without food offerings.

The service could have been better and the food was bad

Muy puntual para la salida y la llegada, personal abordo correcto, la comida regular sobre todo el desayuno triste

This was a very good flight. The seats on the Dreamliner were comfortable and all the outlets were functional. The crew was friendly and helpful. Boarding was fairly efficient, although it was delayed by a baffling search of all the hand luggage for liquids. The timing of this flight, leaving at 10:30 PM, was excellent. It was a good time to arrive at DFW also, as there was almost no delay in going through customs and immigration. I'd fly this route, at this time, on this airline again without complaint.

No WiFi on the plane. Crew was insensitive to my medical supplies and medicine in my carry on. If the crew was monitoring passengers putting 2 bags in overhead bins there would be room. We sat for 2 hours extra. Iberojet is horrible never again.

Great staff, just very far from the main terminal, had to run to connect my flight. I had 90 minutes to spare. But my flight from Chicago was delayed also.

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.

12 hours flight. Only one meal, not enough food. At the galley only water during the flight. Lavatories not clean. Headsets at extra cost.

All flights with Air Europa you arrive late to the connections of other flights, I missed my train, I had to pay for my train again, the crew are antisocial, you are paying for a service, it is not free, thanks to the travelers they are there, it is the last time I fly with them,

Very BAD crew service They ignore at all any call for service . Very rude from the check in process to all the tripularion members in the fight .

Impossible to check in via the App. Kept on getting emails offering upgrade. When followed through not available. Wasn't any food anyway.

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.

After landing in Paris every one in the plane had to get on a bus which was packed and every Covid protocol was violated. There was no social distancing. It was disappointing. There was an empty bus right behind us. A few passengers asked to get on it to keep some distance between people but the driver refused. Probably you do not care.

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.

Staff and Pre boarding good. Boarding also good. Seats cramped no leg room Understand having to stay on board during change at Rio but being arranged to stay in seats for 2 hrs is unreasonable. No drinks or refreshments offered during this period - not even water, to rub it in - trays of drink passing us by on the way to economy plus and business class. On the second leg of flight was six hours before being offered drink/water.
