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.

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"
Cons: "Boarding... always boarding being confuse! Tarom flights are... difficult to understand why this happens"
Pros: "Comfortable’ish seats, left on time... arrived early!"
Cons: "Boarding is, continues to be, a big issue! Not organized, everyone trying to jump ahead of others..."
Pros: "The check in was very rude and moody for no reason. He was not accommodating with the seating arrangement"
Cons: "Ask the staff not to be so moody for no reason at all."
Pros: "The crew was amazing. They answered to my requests politely and helpfully"
Cons: "Some of the plates/tables are not rigid/straight horizontal. Should be checked and readjusted"

50 minute of delay on a flight scheduled after 22pm is really annoying. This was even the only flight departing from Frankfurt Hahn on that evening so the delay was inexcusable

very delayed boarding; the crew started the service extremely late and everything felt like they didn't want to be there and do their jobs; the pilot changed her mind about landing :))))))))) and we spent 10 more minutes circling around the airport before landing, eventually!!! lack of communication = lack of professionalism. she could have said 'ladies and gentlemen, due to us having taken off very late, we have lost our landing permissions and we'll have to wait some more', but she chose to shut up. big mistake that reflects poorly on the airline and herself.

The flight was 45 mins delayed but the crew provided water and necessities like tissues

Flight with Ryanair more than 1,5 hours are awful... No space between seats, absolutely uncomfortable stay.

Flights were on time. The crew was efficient and friendly.

Em relação a Ryanair, ter de ir ao check-in só para carimbar o cartão de embarque não foi muito fácil, são muito demorados, e atrasam a passagem do controlo de passaporte... E cheguei com 2 horas de antecedência

While this flight from Dublin to Venice boarded on time, its departure was delayed by about an hour because, apparently, there were no demonstration kits on board, and we couldn't depart until the safety demonstration was completed. We were informed that we were in danger of losing our delayed slot if Ryanair engineering didn't provide the kits 'soon', which would have resulted in an additional two-hour delay. Thankfully, we didn't incur that additional delay. It's not clear where the source of this problem lies but it needs to be addressed to ensure it does not recur for other flights in the future.

We each paid for 10kg checked in luggage. Flying out there were no issues sharing one case (20kg). Not so coming back. Additional £48 charge and unable to provide an explanation of why it was ok on one journey but not the other, or indeed what material difference it makes between 2x10kg cases vs 1x20kg case. Scam, and appalling from Ryanair.

The flight was canceled 2 days before, without any alternative offer

Flight was delayed due to weather so not much Ryanair could do about that - otherwise it was very efficient and smooth
