Best international flight I have had in a while! Far superior accommodation, services, food and general experience compared to U.S. airline companies.

0lane 2qs on tim3. Very bad food. No free wifi, only for texts. Entertainment poor and hard to access.

At boarding, the locations where we had to have our passports checked prior to boarding were very unclear. Occasional staff wandered around telling people, but in busy area of the terminal this was not obvious. It was also located well after the check in desk in terms of walking to the gate. The Premium Economy service was attentive and warm. The only big draw back was lack of restrooms, and no division or even curtain between PE and Economy.

We had seats between the bathroom and a screaming baby, and did not have enough room to lay my head down on the tray table. Not ideal.

Very nice crew and great food. Easy to board just wish the flight could be shorter or seats more comfortable or more room to walk around when you get cramps in your legs from sitting so long. Crew was great and attentive and really was good food.

My experience was wonderful. The professionalism of the crew was exemplary 🙂. The meals were wholesome and tasty. I have no complaints

Everything was smooth and great. I didnt like that they talk so much on the interphone during the flight.

Even though I paid extra for more room, we were very cramped and the seats were hard. Also, when we checked in they did not post the gate we were to arrive at even though we were half an hour away from boarding. The agent did not know either. Actually, the flight from Porto to Zurich did to have the gate posted, and there were very few agents in the boarding areas who could help us. I would never fly Swiss Air again.

Swiss is the. Only airline I use when I go to Europe. They are on time and they are fantastic!

horrible.. they cause such a problem and my daughter 14 years old was stranded in san francisco

Excellent food and service on my international flight. Most notable is the food provided by Turkish even for coach passengers is very good.

They can my date of travel and let me standard in Istanbul for three days stop over and only pay for one day in a hotel with only one breakfast for three days.

the flight was cancelled and I was rebooked twice, once 26 hours later, then another 24 hours later. In total the flight was delayed for 40 hours. Never again will I use kayak or Turkish Airlines for my travel.

Worst experience with boarding once we left the wheel chair even traveling business we had to wait with all the crowd for the bus to take us to the plane then climb the stairs with our bags When you pay extra for comfort and convenience and you don’t get any is disappointing

Food is very turkish. No regard for other natinalities taste and preference. The entertainment can be improved- it was the same menu on 10/8/25 and 10/25/25. The boarding is the worst in the airline industry- I suggest you ask your staff to and watch how other airlines do it.

The best airline for international travel in terms of value you get in business class (service/cost)

I liked the overall flight experience. However, Turkish officials could do a better job at guiding non-Turkish speakers to their connecting flight gates in such a huge & vast airport.

Very small and cramped aisles and seats. Food was poor but the fresh hot roll and hummus was good. No cans of soda given but they had small bottles of water. Crew was nice and pleasant and kept bathroom clean.

We couldn’t fly to Chicago on our booked flight. The flight was overbooked.

Small seat space for 13 hours flight, they charged for baggage , very bad quality of food,

The seat space seemed small especially when the person ahead reclined but other than that, very good.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

Food was poor quality and the screens for entertainment didn’t work properly

It was a short flight, everything was good with it.

I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

I meant this flight was not good, the one from Tirana to Frankfurt was better!

I was very grateful for Lufthansa's role in organizing mobility support. The touchscreen on my seat was faulty: slow, stained (I couldn't get it clean), and glitchy. This made selecting movies extremely time consuming, and twice I had to start all over from the beginning.

The crew was the best I’ve ever encountered. Business class was spacious, immaculate, and very modern.

The crew was fantastic. They were always there when we needed them. No wifi on an 11 hour flight was a bummer. The entertainment onboard was boring.

I wish seats were not reclinable. It's so claustrophobic when the person in front of you spends most of a nine hour flight leaned all the way back. The crew was really nice though and the dinner (red Thai curry) was pretty compelling.
