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

There were no charge points for phones on the economy seats. The seats were comfortable overall. Food was okay.. flight was on time

The flight was delayed. The aircraft was unclean. Promised seat was not given due to change in Aircraft. Not one crew on ground was in a position to give any response. Amsterdam Airport is AVIODABLE Over crowded. Over Expensive. Poor Services.

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

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

Empty seats next to me - wish it had been for a longer flight!!

I’m grateful for the KLM Air France shuttle bus service to Ottawa. However due to construction and other issues related to the chaotic Uber pickup system at YUL, it’s a challenge to find the Kelios bus service to Ottawa. The signs are not clear or even available. No staff to guide passengers. It’s a stressful experience.

Flight was on time, staff are friendly and helpful onboard.

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

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

I will say the same as my previous comment. Great job over all! From 1-10, ten be the best… I will give 9!

had to wait 1 hour once boarded. so we were 1 hour late arriving.

They are absolutely impossible to get hold of. A death in the family caused us to delay our departure. They are impossible to get through to and after waiting 41/2 hours I was told they would not consider helping us. They cancelled our return flight and have not reimbursed anything. I strongly urge readers to consider a different airline.

A lot of snacks and provided on request by traveller. Preferred meals which were on their menu were not always sufficient for those who wanted them. We were told 2 different items and offer which we asked for were not offered initially. We rejected the 3rd item given as a substitute for our initial choices which we didn't want and so we didn't accept it. Eventually our initial choice was offered. During service of coffee and tea, the crew member didn't offer us and moved back. Luckily neither of us wanted tea at that time. Crew members must avoid behavior that may be suggestive of discrimination

The crew was awesome. My husband fell while traveling to the WC and got a head abrasion. The crew helped him greatly and a physician that was also on the flight checked him out as well. They all get an A+!

Online check in and seat assignments are terrible. All 4 flights

Cabin was kept very hot and it was uncomfortable. Entertainment system did not work at my seat. Crew and service is fantastic

Extremely bad BAD BAD BAD. NEVER TURKISH AIRLINES EVER AGAIN..PIRATES COMPANY.

Typically great service from Turkish with comfortable seat and amenitie, good food and great attention from staff.

Delicious food, comfortable and clean plane. It's a little cramped in the hall in front of the gate.

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

Flight crew was super friendly and helpful. Food was frequent and honestly pretty good. Plenty of on-board entertainment. Economy seats are super cramped for such a long flight, but the crew allowed people to get up and stretch, and kids could wander with their parents, so we all made it work. Overall a very good experience.

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

Outstanding service, great food, friendly & efficient crew, safe & comfortable flight

Staff were not attentive, wifi did not work, cut my head in the bathroom due to the position of the soap on the sink, had blood running down my face, told staff, they had no expression no sympathy, didn't even say "sorry", they said "oh we will have a look at that" about 10 mins later the purser brought me a bandaid, still no sorry.... Shocking

Starlink is great Crew was polite Business class didn’t get a welcome drink just water and snacks were ok

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.

Terrible. Our flight was completely cancelled with no options to rebook until 4 days later.

Generally good. Not their fault but the design of the Boeing 747 had seating supports directly in line with my legs. So my legs always had to straddle this support which caused body misallignment. Such poor design from Boeing. There was no USB port for me to charge my phone. The screen touch control was very poor.

I like crew. They are friendly. The flight was delayed to take off for 1hr and that caused panic at Houston Airport to catch connecting flight due to security check delay. If it has reached on time I would have sufficient time in collecting bags and security check

How about changing the personal out to more friendly human beings? This team was pretty arrogant. No fun!!

Everything could have been better. What needed to be wrong with United went wrong

A shout-out to the flight attendent, Lauren, who was the main person assisting me. She was amazing - perfect balance of bright, cheerful, engaging, yet formal

1st class seats NOT REALLY 1st class or business class but like premier economy. Should be listed as such or named something else. I have flown 1st class with other airlines and they are nothing like it at all.

The flight from Dallas to madrid was delayed for 2 to 3 hours, the flight back from Dallas to Sacramento was fine , but there were 5 gate changes within the span of 2 hours, last one was in a differny terminal. Flight and crew was okay

I was downgraded from business class to economy class with no compensation. American Airlines is absolutely the worst airline for international travel. They treat their business class customers like dogs.

OK, except for a cabin attendant's lack of attention.

efficient. on time. cabin crew were very professional and very nice to deal with. would definately fly BA again.

It was great overall. A few slight improvements could be made on the onboarding process at the Gates with announcements and clarity of communications (both at the gate and in flight). The movies in the entertainment options could be improved for bollywood, hollywood.

I alrady responded to this request, and expllaned at length that this was the worst flying experience in my 77 years. I will NEVER fly BA again.

Airbus A350 is poorly designed for wheelchair users and reduced mobility passengers. The angle of the pods makes it awkward to transfer. I was able to but I have ab stability. It could be a real challenge for people with more severe mobility impairments. You'd think Airbus would have come up with a solution for this or thought more about us disabled folks more when designing this aircraft.

Check-in in SAN was long. ORD was good. Flight delayed On board crew was ok. No warmth or personality. LHrR barely made connection
