We liked the direct flight from Frankfurt to Orlando, however, it was a little confusing as I thought I was traveling with Lufthansa from Izmir- Frankfurt-Orlando. We were not able to check in online twenty-four hours before the flight from Izmir. One lady in our group wanted to check two suitcases in Izmir, but was not allowed to do so. She was allowed to take the extra bag into the cablin. Others in our group were able to check two bags. In Frankfurt several in our group were given stand-by boarding tickets, which worried them. Everyone eventually was allowed to board, but it caused them to worry. I didn't have any of those problem.

Boarding, comfort, food/drinks, entertainment and most of all an extremely courteous and friendly group of flight attendants made my 12 hour flight an absolute joy!

The bad part was 2 hour delay and we were seating in the airplane it was getting hot and uncomfortable But after they fixed the problem everything went so smooth Crew were amazing very nice polite and caring

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

3 hours delay, non comunicated until past the time of original boarding, no assistance, witnessed land crew shouting at a passenger

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

Boarding process makes no sense for priority boarding or not since everyone gets crammed in a bus and everyone gets out without any difference.

Everything’s went straight forward, no issues, good service and friendly crew

It is standard with Ryanair, as FF with Ryanair you dont expect too much, and Ryanair never disappoints. At least it is reliable.

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

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 🤷‍♀️

Usual RyanAir flight but disembarking was poor, no rear steps. The Faro Airport required lots of up step and down steps, no elevator Getting through passport control took 50 minutes in the EU line

Largas colas para el check-in, por seguridad, sin explicación, el equipaje de mano pequeño tuvo que pasar a bodega,

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