Touchscreens do not work. WiFi did not work. Food is possibly the worst on any European airline. Drinks came by only four times on a cross-Atlantic. The plane was two hours late because—it was announced—Lufthansa didn't have enough large aircraft in their fleet to accommodate an on-time flight.

Touchscreens do not work. WiFi did not work. Food is possibly the worst on any European airline. Drinks came by only four times on a cross-Atlantic. The plane was two hours late because—it was announced—Lufthansa didn't have enough large aircraft in their fleet to accommodate an on-time flight.

It was freezing in the airplane. Everyone was wearing everything they had with them. The crew acknowledged it was cold, but did nothing about it

The flight attendants were superb and the service was outstanding. Some passengers with small children were very rude and inconsiderate, kids were constantly crying and some were running around the aisle unsupervised.

Terrible. There was a rattling noise the whole flight. The internet didn't work after I paid. Boarding is very disorganized.

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

The crew member put her luggage and boxes behind my seat so I was able to recline while the passenger in front of me did for 8 hours. My knees were forced against the seat for hours :(. Dude sitting next to me hasn't showered in weeks so I almost threw up.

Sorry my last review for prg to fra was for this flight. My prg to fra flight was fine but my second flight back to Washington DC was with a slow awful crew who wouldn’t come in a timely manner to take trash and take trash before serving coffee tea and was shoving other people’s bottles of water on me when we were not traveling together

Lufthansa was amazing. Definitely upgrade your seat if you can swing it - they take very good care of their passengers. Customs in DC is nothing short of a nightmare though. Stood in line waiting to go back through security for 30 minutes, had to RUN through and across two terminals to make my connection and only had 5 minutes to spare. Terrible. Very very poor coordination by the airport staff and CBP.

I was ver pleased with the service all the way through

I always try to book flights that don’t charge for baggage. Yet I was charged $75 for this flight.

flight delayed, no information given until late on, Ryanair app said "on time" until 5 minutes before expected departure time, crew rushed us to board, when it was already 3 hours late

Good flight. Take off a little late but make up the time

Ryanair is the worst airline in Europe and easily one of the worst in the planet

O voo atrasou um bom bocado A tripulação não era comunicativa,não fez vendas... Não abordava os passageiros... A 1°vez que me acontece tal coisa 🤷‍♀️

I hate Ryanair and have decided never to fly with them again, they treat you like animals on the way to slaughter and they never take responsibility for their errors and lousy service.

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

I didn't like. The seats and the floor were very dirty and it is not the first time

On time but no water , milk or refreshments of any kind on board. Which is poor, especially with children and elderly on board. Toilets filthy,

Bag check in was terrible. Arrived 2 hours and 10 minutes ahead of required time and then waited 50 minutes in line to check ONE bag. There were 4 employees standing around as only two were checking bags and there were 6 gates available to check bags. Process is terrible. Lack of customer concern and service.

Pros: "Not much"
Cons: "The CHEAP profiler of a CEO this airline has as its head. As it stands, Ryan isn't worth saving."
