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

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 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)

Terrible last row seats many seats available but no offer to move to better seat

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

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

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.

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.

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

This was my third time using Turkish Airlines. I was well satisfied with the overall experience! I believe that no one is perfect and that everyday we are trying to do the best we can to help others by giving a part of our lives through service. I believe from what I’ve seen that Turkish Airlines, have come close to that service! I will definitely recommend and reuse their services again! Thank you!

Flight was late but loading plane was much easier in Istanbul than athens. Food was so-so and choice was limited. Flight attendants were extremely courteous and helpful; however, it was difficult to get attention during night time service. Overall good experience and the price was right

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

It was terrible. sat on airplane 2 hours then flight was canceled. made to pick up bags and go through Panama immagration to rebook another flight. worst experice ever at a airport.

Good but airlines getting smaller. I didn't like the meal but the service was fine. Flight was fine and luggage arrived. So good.

Lounges are packed and very poor, food is really bad, for business class in an airline is well below expectations

First time flying with UA and it was a great experience. Thank you

Overall flight was ok. Flight attendant was receptive to assisting passengers with tight connections.

This was the first flight in the morning. We boarded fine. The cabin door was closed and we were ready to go. We were notified by the Captain that ATC issued and ground stop for 40 minutes. So, without even pushing back from the gate, we were already 40 minutes late. We actually were released to push-back and taxi at 30 minutes. But, some passengers had tight connections and were not going to make their connections. Some passengers asked about the delay and the effect on the connections and were told by the cabin attendant that all flights will be delayed and so they should be OK. However, that was not true. My connecting flight was on time and I arrived at IAH with 21 minutes to make my connection. I did and I'm happy about that, but the flight crew should not have given assurances to the passengers who might have missed their connections.

It as confusing with the connections and I almost missed my next flight because of the first delay with the first flight. United could have helped passengers go through immigration quicker rather than waiting with everyone else. The flight attendants were super friendly and lovely. The vegetarian food was awful- I did not finish. I would suggest they just do pasta next time

Boarding was again a "free for all". We were boarding group 4, and almost the entire plane was able to board before us. It's a shame that someone who follows the rules, gets the short end of the stick. Not fair.

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

We purchase first class seats for the first time for multiples of standard economy ticket. There was no access to the club lounge and no priority boarding. The meal and the service once on the plane were superior and the seat was nicer, but not worth the price difference. I will be happy to seat in economy and spend the difference on more travel.
