The flight was 45 mins late leaving, we sat without a/c for some of this, 2nd Meal was a slice of pizza. Movies were good.

Brand new plane lots of room the snack was very flavourful and enjoyable

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

It was really nice experience by flying this klm flight.I personally recommend everyone to please try this klm flight

It was really nice journey i personally recommend klm flight

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

Flight was ok but lack of communication cost me to literally beg to be put on another flight as connecting flight had departed

They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

Gate agent showed up 20 minutes before boarding and was not at all friendly. Had to take this flight due to the one on the day before being cancelled and any later options were already full with long standby lists. Despite having paid for Delta Comfort seats, Delta did not allow me (or anyone) to choose their seat. The agent assigned them for everyone just prior to boarding. Self seat selection was allowed on the original flight. Flight staff was great - very friendly.

Crew helpful. Plenty of food although not great but ok. Good time.

Flight attendants were great. Cheerful, upbeat and friendly. Jet, in particular, was fantastic.

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

Original flight was delayed, then cancelled and the gate staff did not expedite rebooking. Also, no instructions were given that a ticket number was needed before being called to facilitate rebooking. This could have been much more organized.

Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

Five hour delays every hour, I wish it were all at once

Flight delayed four separate times. I’m now one hour hours late to landing.

worst flight ever from Delta, it got delayed and kept on delaying..

Should never have had to go to Detroit from Orlando back to Tennessee!

Older plane with finicky seats. Crew often seem to focus on "pet" clients and over extend services to some over others. I get less attention since I'm not a regular business class client. Regardless, I've paid the money and would expect equal attention.

Our flight attendant was stellar with great anticipation and attention to details. Food was very good, and overall flight, though very long, was really good.

Great food, and lots of it. They made us come to the gate two hours before the flight and you were stuck in the enclosure until you boarded with no bathroom or food or drink. My seat in business class was very claustrophobic, I could barely get into it and a large board blocked the window and made it even more claustrophobic

Turkish Business Class is a wonderful experience, and the best inflight dining experience I’ve had to date.

The crew was amazing and the food was really good too

Some of the best service I’ve ever seen on an international flight! The staff were super friendly and accommodating. The food was excellent with lots of choices and attention to detail. The seats are kind of old and narrow, but I have wide shoulders. The only area for improvement was making the cabin a little cooler.

It was fantastic. I really enjoyed it. It’s comfortable the flight attendant. Respect you anything you ask for they gave you except the water.

We were experiencing delayed for 4 hours and of course they took us to Turkish airlines lounge but we could not rested up since there is no bedroom. It was tiring and long day for us🙏 Especially we didn’t fly until 5:45am morning for Miami🙏😢

On Turkish it is all about the food and the service. I am overwhelmed with the quality and variety of the dining service offered on business class. I prefer the updated A350 to the older B777 cabin layout, but both are comfortable. Flights left and arrived on time with updates from the captain. I will definitely fly with them again.

Excellent service. Friendly and attentive flight attendants, can lay back in business class and be pretty comfortable, and delicious food. Flight on time departing and arriving.

The food on this flight was better than what we had getting to Rome. The flight was comfortable and the staff was great. One of the staff members was a stickler about the blankets in the aisle, which I get, but still. Overall, great flight and will fly with them again!

Our screen kept turning off ...3 times...had to get crew attention to turn it on again

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

Perfect airline, super friendly, great service, tasty food. Would fly again.

The flight attendants were wonderful - one man put my carry on in the bin for me. Very attentive service. Loved the blanket and pillow waiting for me in economy. Food was excellent which is a surprise given the reputation of any airline food. Wine was fine with the meals. Delighted with the new movies - flight went by very quickly. I would definitely fly Lufthansa again.

Flight was delayed by several hours and then cancelled due to weather. But Staff was very helpful getting me on a different flight. United should offer food coupons and tooth brush and paste for stranded passengers

Service was excellent. Flight was only about half full, which meant we had tons of room to stretch out. Boarding area was nice and well organized, flight attendants were super friendly and attentive and we loved the 3 snacks!

My flight was cancelled, but it was not Kayak's fault. Kayak did require me to pay for the ticket twice to two different venders who paid Lufthansa. Kayak/Lufthansa owes me for the first booking I made first was fraudulent on the part of the subcontracting ticket seller. There will be litigation over this issue under the current passenger protection laws.

flight was half full, plenty of empty seats, was able to lie down across 4 seats, food was good, arrived on time

Was never allowed on and not refunded the full amount of the ticket plus charged a $300 processing fee.

Thanks to a delay of an hour of my flight to Philadelphia on American Airlines I missed my connecting flight to Amsterdam. On arrival at Philadelphia he crew on the delayed flight did not ask the passengers to let connecting passengers get off first and I arrived a few minutes after boarding was closed at the original time for the flight to AMS, this despite the fact that I had received a message from American Airlines that departure was delayed by 25 minutes. Overall very poor service, no effort from the part of American Airlines to accommodate the passenger, just rebook the flight for the next day.

Seats not as comfortable as I had hoped. Food was very nice, service was fine. Entertainment options very nice. Had thought the premium economy was a more plus 2-3-2 layout but it was a 2-4-2 with seats not as wide as I had expected.

I liked my seats on the return trip. Didn't like having to pay for luggage on an international flight. Also didn't like that it was on American airlines and not British Airways. I specifically selected a BA flight to experience that airline.

I flew four flights on British Airways within two weeks. I was unable to download the boarding pass to my phone for any of the four flights. I could check-in for my flight but the system would not give me boarding pass. I tried multiple ways and multiple times. I discovered many other passengers also had the same issue with their boarding passes. No explanation or acknowledgement by BA.

Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays

Because our ABZ-LHR flight was cancelled by BA for reasons they refuse to tell us--not weather--we did not make this flight and were booked on the following day. BA offered no assistance to us on the phone or in the airport, and we had to find a hotel at Heathrow on our own.

Horrible - flight was delayed by 6 hours - we boarded, were made to de-board due some technical fault; aircraft changed; special meals request on new flight - all went awry. Landed in Dulles airport; breezed thru immigration; as Business Class passengers or baggage was delivered almost 90 minutes after landing; air tags indicated the bags were just near the carousel but the unhelpful BA staff - Maria and Ghina refused to give any update - palming it off on some imaginary invisible “manager” despite air tags evidence showing it right there. So about 50-60 passengers waiting and getting infuriatingly impatient for their bags coz one container was not delivered. Finally after much argument by some other passengers Maria condescended to go to the “ramp” and within 5 minutes the baggage was delivered miraculously. Question is why couldn’t she have done it one hour earlier ? Poor poor experience once again on Business Class BA.

Cheap Flight Fares would not provide booking info. I canceled the reservation and we arbitrated with American Express. They provided erroneous info to Amex and it was determined that C.F.F. deserved the price of the ticket. Worse experience I've ever had.

Seating space is appalling. Seats and all surrounding area in "Economy" is built for individuals shorter than 4' 10" and below 120 lbs. Ridiculous. While I'm not expecting fine dining, the food was the worst airplane food that I can recall.

My luggage was lost at the airport but American Airlines contacted me and got it to me the next day.
