Uncomfortable seats. Crazy seat assignments separating families when they could easily have put them together. Good communication from pilot about arrival time after delay in departure. Toilet ran out of water in sink. Snack box poor for flight of this length.

Uncomfortable seats. Crazy seat assignments separating families when they could easily have put them together. Good communication from pilot about arrival time after delay in departure. Toilet ran out of water in sink. Snack box poor for flight of this length.

The bed in Club class was not very comfortable, everything else was good.

Cancelled flight minutes before boarding. Rescheduled flight was two days later

The flight attendants were EXTREMELY personable and appreciated the service, lights going off after dinner (probably the norm, but I haven’t flown evening overnight flights in a while). Thank you!

Great room between the seats, food was excellent, very comfortable overall and could have stayed on the plane even longer

I have noticed that the airlines, including this flight, pretend there is going to be turbulence, announce such, and say they can’t do beverage service. There is no turbulence and the seat belt light goes off 10 minutes before they ask for tray tables up and seat belts back on. They are just trying to spend less money and it’s quite transparent

Business class seats were very dated on my plane. Very little storage, charging ports were not easily accessible, tv screen kept flopping away. Vegetarian food was disappointing: hardly any protein and severely under-seasoned. Crew was lovely.

The food was ok, but not great. They delayed boarding in Portland and did not enforce group boarding. But the crew was excellent, went above and beyond.

The food was pathetic. There wasn't much leg room and recline space for such a long flight. No tea/ coffee for a 2-3 hour connecting flight without purchasing! Really!?

No longer a premium carrier and no better than the low cost .

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"
