Very hot cabin made long flight uncomfortable, even in business class! Food was great. Istanbul business lounge had great food but too few bathrooms and seating . They also need more electric outlets for charging devices. Appreciate the ability to go through fast track lines w business class

Very hot cabin made long flight uncomfortable, even in business class! Food was great. Istanbul business lounge had great food but too few bathrooms and seating . They also need more electric outlets for charging devices. Appreciate the ability to go through fast track lines w business class

The crew on this flight provided exceptional business class service to me.

The staff at the boarding or the rudest uninformative and no English whatsoever they’re very rude as if they are envious of you travelling I don’t understand how could someone would be this rude and this out of touch and cold

You charged me for luggage although the airline does not- you charged me for seat when customers can pick their own seat at checkout in I travel to Europe slot and I will not use kayak again

It would be great if the flight attendants could inform people travelling with small children that at take off and landing the children should drink liquid or chew/swallow something so their ears don’t hurt. Also, Emirates serves the food to the children first. Really good idea. Best of all would be to put all children in the same area.

I had issue with my boarding pass. When I arrived in London Gatwick Airport. My e-ticket wasn't scanning and had to do a lot of back and forth with Air Transit I order to board my flight, which I almost missed as a result of this.

Requested food options were always finished. Supplied food items were good but of course not the desired choices.

The airport staff never announced that boarding has started. Both at iad or Islamabad or Istanbul.

Very bad experience with turkish airline tk 0001. Very uncomfortable seats and food ran out and crew was not helpful

The airline could improve its business class seats and privacy in line with its competitors.

wifi was iffy at best. Movie selection could have been better

Boarding was chaotic and confusing. The seats were so close to the row in front that my knees were up against the seat in front of me the whole trip. The beverage service consisted of a small plastic cup of warm water. This was truly a very bad experience.

A basic, cheap flight from Bucharest to Prague. No Frills, but we got there safely.

It was cancelled you imbeciles! And then you have the gall to ask for reviews? Here! Have this review, you damned cretins!

Upgrade to business was great. The crew was nice. Disembarkation in Bucharest was very slow through the rear door to a bus to get to the terminal. The business lounge was not clean with bugs running on the floor.

I rated food and entertainment with the lower score because I did not have N/A. No food and entertainment from Bucharest to London.

Poor service ! Water need to be free and a little snack for 3.5 hour during the flight. Tarom company need to take lessons from Turkish Airlines.

There was extreme turbulence for 10-15 minutes a bit after takeoff, which of course is no one's fault. This was a short regional flight with no amenities except water. Departure and arrival wete close ro on-time. The Suceava airport is very small but pleasant and efficient. My baggage all the way from Washington DC, checked through Paris and Bucharest, arrived without a hitch. There was really nothing to complain about except a regrettable 5+-hour layover in Bucharest.

This experience was atypical. The flight left three hours late because of engine technical issues, which meant a very long wait. Unrealistic announcements made it worse by discoursgong leavimg for water, reatrrom, etc. But the crew did its best and apart from the delay, it was not a bad flight. Good entertainment and drink service.In the end, I made my connection anyway.

Pros: "The crew and the flight from Bucharest to Istanbul"
Cons: "The airplane from Athens to Bucharest wa terrible, very old, smelling bad, not maintained, and noisy"
