The internet was not working during the 10 hour. This situation was known by the cabin crew before the flight. If so, information should be given to passangers. Some people should work during the flight.

The internet was not working during the 10 hour. This situation was known by the cabin crew before the flight. If so, information should be given to passangers. Some people should work during the flight.

Seemed like a cramped A321 config. Roasting hot cabin most of the flight. Wifi did not work. Lots of first time fliers, I think, who didn't know how to follow a seat assignment.

I have been flying Turkish Airlines for the last 5 years it’s always great service, on time , excellent food, only one thing wasn’t reliable is their on board WiFi most of the time it doesn’t work.

My checked bag did not get loaded on the aircraft in Istanbul. Other than that, the flight was smooth, on time and the crew was friendly, efficient, and professional.

You need to weight all bags together because we were 2 and we allowed 4 bags plus hand carry and personal items. We trying to saved bag like we put our stuff in 3 bags so we don’t have to carry more bags and airline also save space time less bags less work. We had only 1.6 kg over and we requested crew he said it’s airline policy that you need separate bag that’s ruined our mod and carry that suit in our hand in plastic bag he didn’t understand that we have less bags that make sense if we brought over luggage then it’s problem. I think if you guys change your policy and weight all together that will be good

Unfortunately internet was down and they couldn’t fix it in a time I needed it so urgent to stay in touch with work

Better than other airlines but still not at the top with other airlines that you pay the same price and services and customer service are much more well performed with care and attention to the customer. Still a long way to go. Some of the flight attendants are speaking English like they translate direct from Turkish. They need to improve the customer service for a global travel.

Boarding at Istanbul airport is pretty good. The seats on the A319 are easily the smallest and tightest I’ve ever flown. I’m 1,82m and knees firmly against seat in front of me, as upright in seat as I could get. Very uncomfortable

After boarding cabin was too hot AC didn’t work

Not sure how they are rated best airline in Europe. If they are the best; then I worry about the overall airline standards of European airlines. Seats were very uncomfortable and almost closer to budget airlines in terms of comfort. A sore bottom after a long haul flight ruins your holiday at the start. Check in process was okay. Staff/crew was good - interactions ranged from pleasant to borderline rude (depending on the particular individual).
