Great boarding, great short flight but no entertainment whatsoever. It was supposed to have wifi but that did not work.

Great boarding, great short flight but no entertainment whatsoever. It was supposed to have wifi but that did not work.

Transfer at CDG to connecting KLM flight to Amsterdam was a NIGHTMARE. LONG WALKWAYS, NO MOVING WALKWAYS, POOR signage, Have to take a train & No staff visible to help navigate the maze. AVOID TRANSFER AT CDG AT ALL COST.

There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

I tried to upgrade to premium economy anis seat online during the checkin process. The payment didn’t work due to a technical glitch on KLM’s website. I wasn’t able to change my seat unless I called Amsterdam. Since I was in Canada and there’s a time difference this wasn’t practical. So when I arrived early to Ottawa airport my seat wasn’t available and I could only get a middle seat in premium economy which isn’t great. These middle seats are priced at the same rate as an aisle seat which makes no sense.

The food & entertainment really stood out in terms of quality. The nasi goreng & chicken satay were absolutely delicious. It’s great that KLM feature international cuisine.

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

Transavia flight. Couldn't select seat or anything prior to flight. No connection with klm systems. Seats are very crammed. Extremely no frills.

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

Flight left a few minutes late, but that's it. I wish the seats could be wider and recline more.

The IFE was quite old, but it worked fine and the content was good. The cabin crew were excellent and the food was as also very good

Same as before boarding process and lack of crew experience in the process

Turkish Airlines is amazing. I have a problem with the ticket I purchased through the kayak website. I have filed a complaint related to the fact that I was contacted by phone on the day I purchased the ticket and told that the amount that the ticket had been advertised for was not accurate and that I had to pay more. This is totally fraudulent. I will look into addressing this further tomorrow and will never ever use kayak again.

Bad service and food was not good. Give very less food.

Crew members, pilots and flight attendants are excellent. Beside, that, customer service is very lacking in all aspects of Turkish airlines

The ac did not work and the plane was deployed for the AC BUT IT NEVER WORKED. I have high blood pressure and I was SWEATING AND NEARLY PASSED OUT. Do better.

For me it was a good experience… thank you Turkish Airlines

Old aircraft, very very low business class standards, no privacy between the seats, horrible old TVs, tiny bathrooms.

Good service, the airline also provided a traveling kit bag (tooth brush, socks, slippers, visor for sleeping).

The seats have to be one of the worst when it comes to comfort and you have to scramble around to out your handbag in the overhead. The food is still awful. Definitely will not travel on Turkish again and wouldn’t recommend it to anyone for sure.

It was very good and it was not my first time I always take Turkish air line for my travels

Seating was horrible. Small seats. Access to flight information and extras very iser unfriendly. Kept losing internet after paying for it. Staff in madison was as unprofessional and unhelpful.

Delayed due to no crew. On a major holiday travel day.

Other than being delayed 5.5 hours and having to get a hotel because I missed my connecting flight, it was an okay flight. No in-flight Wi-Fi or entertainment.

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

3hour delay In the last 3 months i had 3 flights and 2 of these had a more than 2:40 hrs delayed

My initial flight to ORD was extended without reason. We circled the airport a few time and then drove on the ground for at least 20 minutes. These kinds of delays are annoying but somewhat expected… it would be nice if the crew would make an announcement to give updates on how long we could expect to be delayed.

Fantastic. I am low vision and was impressed with how helpful and accommodating the service tam was. It was super appreciated! I was pleasantly surprised about how delicious the food was. Like, “I wish I had more even though I’m no longer hungry” delicious. 100% enjoyable trip.

The boarding system was all bogus - employees at the boarding gate were not sound like proffesional or may be possibly rational

I got an email in the morning of the flight 1/7, from Kayak, that I was rebooked from UA 906 to LH 430. Nobody at Lufthansa ot United knew about this. I went to both counters. at the airport. Also, Cheap Flights, who I booked the ticket through, did not know. I ended up staying on the United flight. But this was very disturbing, since I got a very late notice that I was rebooked to an earlier flight, I hurried to the airport to find out after a lot of inquiring that this was a mistake. Not a good Kayak experience.

After living in Europe for five years and flying with Lufthansa and KLM airlines, I’ve realized that United Airlines is now a budget carrier. The flight attendant are not friendly. The seats are not comfortable. And everything comes at a cost. I will be flying with KLM and Skyteam like Delta to the US going forward no doubt. United Airlines is not what it once was:

Delayed take off but I think they waited for passengers.

I had to fly United where the flight crew was atrocious

Flight was delayed for no reason and I missed my connection. This added another day of travel and I missed an event I was traveling home for.

I traveled with my sister, however ,we booked a flight separately, and we don't sitting next to each other. The staff on the board where on the top of this unit they find us sitting together. Ty lufthansa team. U are the best

Courtesy of waitress. Could improve on time management and check-in

Other than the delay of flight, this crew tried to make the best of bad situation.

Terrible. Super uncomfortable/less room than a domestic flight and flight was 9.5 hours. Food was terrible. Flight attendants slammed the cart into 2 people in our party numerous times as they were both over 6' tall and sitting in the aisle.

Was very bad the cancel the flight after when we arrived to London

Less than average, low level of shared required information needed during the transfer from airport to another, also the used team during boarding In Indianapolis station is Not Professional

Reliable, great value, but not outstanding in any aspect. This is similar to the experience you get in most international carriers like Etihad or Delta.

Flight got diverted because of an emergency and the crew were fantastic and probably saved that passenger’s life. While in emergency landing some measures could have been taken to prevent additional delays. In general not great experience with BA. I used to fly BA years ago all the time, very disappointed by the whole experience, seats were tight, bathrooms tight.

Business class area too small and chair and equipment not comfortable .

Lost my luggage in London Was double charged for luggage

Boarding could have been better organized. The one member of staff disappeared for a while so boarding by group relied on honesty.

I never made this flight but the staff helped to get me rebooked (see previous review)

No land services during boarding, specially while moving from terminal to another

Even the carry-ons were not allowed and upon getting down, we had the wait for the longest time for the baggage to put on the jet aisle. We had a short connection which British Airways kept changing and made out entire experience poor. I would never fly BA again.
