KLM is my favourite airline. Never ever let us down.Staff are first 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.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

The food from Lagos to Amsterdam was was very poor compared to AMS-YYZ

The flight was delayed for 2 hrs. Because they didn’t have a crew to fly. And it is not a first time for klm to do that. Last time they cancelled my filght and rebooked me 3 days later. Not reliable airline

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

I thought KLM was the best airline but the Lima - Amsterdam was 1 hours late, the Brussels - Amsterdam was 2.30 hours late and the Amsterdam - Lima was 30 minutes late

no issues at all... Kudos to the food. This time was really really good

The food was ok. The crew seemed like they were cranky. I had one guy get mad at me for passing in between the storage area to get to the other toilet. I can understand if it's not allowed but reprimanding me like I'm a student saying "This is the last time!" was not appropriate. During my meal time, there was a French family around me. No problems there but when we usually have meals, they are supposed to put their chair in the upright position. These people did not do it and the steward did not tell them to raise their seat in the upright position. However, I was told to do so! So, me and another person next to me had to eat with the monitor almost touching our faces. Furthermore, a lady in front of me was putting her feet up and preventing another elder passenger from putting her seat back. To make it worse, she was continuously hitting her back into her seat, shaking my monitor while I was watching a movie. A crew member did speak to her about it but then she accused me of pushing her seat forward! The crew member gave me a death stare and told me to stop pushing the seat forward. I did not even touch her seat at all, if I did, she would know it. Her boyfriend also stood up and tried to push her seat even further past the maximum decline to no avail. None of these people were reprimanded but the steward, some bald guy, was extremely friendly with them and did not even try to instruct them to do anything until it was time to land. I resisted the urge to really argue with them because I would have obviously been seen as the aggressor (I have no idea why). I hardly said anything on this flight except "more wine please" and "sorry" if I bumped into someone accidentally. Overall, it was an annoying flight and I had to resist the urge to yell at the steward and the people he was overly friendly with. The happiest moment of this flight was leaving it.

We waited 4 hours in the flight to take off but then the flight was cancelled.

It was ok. This flight was for my 80 year old grandparents and when they arrived to Beirut no wheelchair (as requested) was waiting for them. My grandpa had to pick up his own luggage, he got soooo tired. No one to help him as we submitted the request ahead of time

Terrible seats are very uncomfortable and narrow. Really hard time eating and painful buttons.. crew was very rud not allow anyone to stand not even to go to the toilets

Overnight flight in the old style Business class, but still very good.

I was in business class, without the business class amenities. Large seat with lots of legroom, but no TV or bed. Food was okay, but I did enjoy the Turkish red wine.

Excellent service and comfort from the moment you check in. Flight crew is hyper focused on making passengers comfortable and at ease. It’s like a flying hotel!

Only chicken as a meat dish through out the flight

Nothing really was great as such. Seen other no name airlines perform better.

Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers

I’m unclear why I had to pay extra for assigned seats as Turkish airlines did not honor the seating. We were placed across the aisle from each other on TK 34, and were seated behind one another on TK 694. Because my name was misspelled on e-ticket (Klawiter, instead of Klawitter) I could not log onto website to get the connection gate number in Istanbul. The monitors in the airport were a jumbled mess 1/2 Arabic and 1/2 English.

Clean and plenty of room for handbaggage. Leg room was cramped compared with the 777 from Frankfurt.

Lady was a bit rude during boarding and I was being nice to her.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

Not a fan of the diagonal partially enclosed business class seats or how they have to be converted to beds manually by crew. I prefer more isolation and user control for switching to lie flat.

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

There was a group of school age passengers that were very loud and unruly with their chaperones were no where to be found.

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

I liked everything about the flight. The service was excellent!

Delayed a day due to snow storm. Was upgraded. That kind of made up for significant delays from FLL to COS with no compensation or acknowledgement.

After a bad experience of traveling with United airlines long time ago I decided to give them a second chance. And again it was bad. The flight from Jacksonville to Washington was almost 4 hours delayed. Due to that my flights to Munich and Warsaw had to be rescheduled. As a result I had to travel through Frankfurt. And my checked in luggage did not arrive from Frankfurt to Warsaw with me. Warsaw was not my final destination and I had to figure out a way to deliver my luggage to my destination. On top of everything my Delsey luggage got 2 cracks. Is anybody going to be responsible for that???

We bought tickets with Lufthanza from Kayak for flight operated by United..

Staff was helpful. we left on time and arrived early to destination.

the flight was delayed by 2 hours at origin and i missed my baggage at the destination

It was disappointing that I could not sit next to my wife but I was not allowed to pick my seat

Absolutely horrible HORRIBLENE! United airlines failed on every front. My trip was silosem to takę 17h nad endem up takimi 47h! I was treated poorely and I wasn’t reimbursed for all the problems.

Due to flights being delayed, we missed our connecting flights and we were flown to a different airlines and we end up losing our luggage's.

I had a family emergency and couldn’t board and I contacted underpricer to help me get a refund or just a flight adjustment as i would still be flying later that week, and that hasn’t happened. I will never book a flight through kayak/ underpricer ever again.

Full flight with ok comfort levels. Zero in flight entertainment. Dinner served was fair… taste mostly ok (bread a bit stale) and way too little for such a long flight. Technical stop in Cyprus just to switch crew which seems unnecessary. (Other airlines from Europe who do not want overnight layover in Beirut do not switch crews.). Thought that some passengers would disembark in Larnaca (CY) but no, stop was solely for crew change.

In general the flight was good, for me the only issue was I couldn't connect to the Wi-Fi

Baggage handling was very poor, I didn't get my luggage for 4 day's on way back. Neither a responsible person to answer my call. Kindly see my call log on lost luggage reference no BOMBA41916. all details are recorded. Difficult to convince me to fly once again. Sorry for harsh words.

Every flight was late in arrival, last was late in departure and late in arrival, then lost our luggage!

The flight, food and entertainment we all decent, except for a mishap when an attendant accidentally dropped a hot breakfast plate on my son who was fast asleep two hours before landing in London. She was very apologetic, and offered to help pay for any dry cleaning, but we have not received anything from BA. What could have been better, however, was the lack of any support upon landing to make a connection. The original flight from LAX to London had been delayed, so our time between flights had been cut to only an hour. There was no staff helping direct us where to go to get through security. When we approached anyone to ask for help, they acted bothered. I was traveling with four children that needed to use the restroom and get cleaned up after the spill, so we had to stop briefly for that, but again the gate notices directing us where to go only said to get to concourse A, there was no gate assignment. It was a busy time at security, and the process was slow, but we still arrived at the gate 10 minutes before the scheduled departure only to be told the gate had closed. We came to find out that our connection to Paris had actually taken off 5 minutes early, but without us, and six of its passengers. British Airways had to be aware of our delay and known that we had made it to security, but did not make any effort to ensure their passengers could make a tight connection through a crowded airport. Rebooking a flight for 8 hours later was not a pleasant experience and when we finally arrived in Paris at 1:00am, we arrived with only two of our six bags. Again the original flight was okay, but the support on the ground was greatly lacking.

It was pathetic. The flight was delayed more than 24 hrs. It took off next day 23:50. The staff was very unprofessional; nobody provided any information on 26th jun. Simply asked to make your own arrangements. Next day also, it was almost 3hrs delayed. Very poor communication to the passengers.

My flight was cancelled for the second time in the Raleigh to NY route .. Cancelled going from Raleigh to NY and then cancelled again from NY to Raleigh going home. Weather was the stated cause but the weather did not seem overly bad anywhere. They blamed lightning but I lived in Florida and planes constantly took off and landed in lightning conditions. I got the feeling that the flight was under booked and it was simply cancelled... The folks at the gates were nice and helpful (not their fault) but it was extremely frustrating and painful to get around those two cancellations. I missed one whole day of my vacation and had to rent a car going home in order to make it back in time to pick up my pet. The hotel I had to get going and the rental car I needed going home were both not covered by American making my vacation much more expensive. I do not think I will ever use American Airlines again.

The staff were so supportive and food was delicious on the flight. Always enjoying flying on BA!

Food could have been better. It was much better on the LHR to SFO leg than on the return leg.

The flight was on time, the plane was at the gate, and then the excuses started. First, it was a part that was needed, then it was short on staff, but they're due to arrive soon, and finally cancellation. Two large triple 7 planes to London were both canceled, leading to over 600 people looking for another flight, which of course was impossible. I had a one week holiday and was forced to spend two nights in hotels in Chicago. Just appalling. I doubt I will ever use American Airlines again.

Horrendous, the worst ever. I would not fly with them again

Horrible service. Lack of courtesy and professionalism from some cree members
