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.

First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.

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

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

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

Entertainment system did not function. USB ports did not function. Wi-Fi did not function. Terrible trifecta…

It was very good. The flight was delayed and people that were boarded needed to get off again but overall it was very good.

I will NEVER fly into our out of Charlotte NC again!! My arriving flight there was delayed over 25 minutes sitting on the ground waiting for a plan to leave our gate. This caused me to miss my connecting flight to Chattanooga. When I did get on my connecting flight there was yes another ground crew issue resulting in a 30 minute delay in leaving the airport. Not to mention just 3 people checking passports for incoming flights.. That airport is not worthy of being an international airport and show the US in a VERY poor way.

Flying since the 1970's and this flight had the most enjoyable food not the take it of leave it chicken or pasta selection. A380 superb

One checkin and gate attendant was very nice. Another was just making everyone check their bags and slowing down the boarding too. This was an A310 so good over bin space. Seats kind of weird, cushion sticking up in the back pushing forward

The food on my AA flights was horrible, it wasn't filling either. Additionally, my bag was delayed and was damaged when delivered. However, the airline made it impossible for me to file a complaint. Had a stressful travel as multiple flights were delayed, causing unnecessary stress due to fear of missing connecting flights. Awful experience. Experience with British Airways was better than American.

I wouldn’t like to have been told what gate I would connect at ahead of time. It was rather stressful, considering the fact that I only had an hour turnaround time between flights

Luggage did not make it onto my plane. Business seats were economy with empty row seat. Just horrible experience. Why would the company allow for transfers that don’t give employees enough time to transfer luggages??

For an long range economy flight I feel more space and more meal options need to be offered for flights over 5 hours

The check in agents in PHL and gate agents had to have been the rudest women that I have ever encountered; the agent weighing the bags at check in screamed continuously at all of the guests as did the woman at the gate.I have Executive Platinum status with AA and fly a lot with AA but these ladies were the absolute worst I had the displeasure to encounter!

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.

My bag stayed in London - it didn't arrive in JFK and I was informed it would arrive at my address next day. I'm still waiting for my bag and it has not been delivered. I have an air tag, my bag arrived at JFK airport around 12pm and it has been moving between terminals since then. Now they said it may arrive 1 am or tomorrow. I'm jet lagged from my flight from India, without my suitcase and may need to miss a work day (Monday) because my suitcase was not delivered at the time it was promised (today, in the afternoon). The suitcase delivery service is not reliable and I'm not happy waiting around the entire Sunday to hear that it may or may not arrive today.

The worst experience with British airways that left me with a delayed flight until the next day and no hotel accommodations available or food voucher. I still have had anyone follow up on this matter

Always the same, boarding starts before the plane is ready so we were all standing in the sun and 36 degree heat on the tarmac. Once in London, packed like sardines in busses to the terminal. BA have a way of making you feel like they dont want you as a customer.

We boarded late, sat on the plane for 45 minutes, I was sweating on the plane and there was a child that screamed and kicked my seat almost the entire flight. The parent nor the crew would do anything about it. Food was very good.

The crew member of my cabin was excellent. The flight was delayed due to air traffic in London. I worried about my connection. The flight attendant eased my worry with prompt updates on the current flight status, as well as helping me log on to BA.com to find out the exact gate info for the next flight. Truly appreciated his help.

Meh. Lived the seat. The entertainment unit did not work and had to be reset 3 times. Service was SLOW taking over 90 min to be served. Crew forgot about my meal. Chicken was dry and almost inedible.

Disastrous. Creeping delays and cancelations. A routine 2-1/2 hour flight turned into a 12 hour nightmare and getting dumped at London Southend at 11pm instead of at London City. This required a £150 Uber ride to East London at 1am. We lost an entire day.

There was an older steward, he is top notch. He is very attentive at the passengers. I do not know his name. Thank you to him.

Good was great. Some of the older crew were grumpy and not customer friendly.

Everything about the flight is better,just to work on the food Everything about the food is very poor
