Big delay on run way not much explanation why, missed a important meeting in Dublin, maybe if they did nt persist measuring everyone bag over 2 cm we would have got off on time.

The lady at the boarding gate was so rude. She was challenging people being in priority and looking them up and down as if they weren’t dressed for first class. This was Ryan air priority. We all sit in the same seats. She loudly called out to embarrass a man who she believed had cheated and got in the priority line. He had a valid priority ticket and even worked for Ryanair. Also challenging visas insisting people download them until they proved on the government website it wasn’t required to print. The Ryanair employee who was challenged said she is always like this. She also pulled people from regular boarding as they were fashionably dressed and upgraded them to priority and changed their seats. That was comical. I think she felt she should be working for Emirates first class, although they would t have stood for her rude behaviour

If you buy a cabin luggage, but don’t need it for your kids, so you will end up with mixed priorities. And you will need to use non priority line

Miserable staff did not want to be there. Very poor atmosphere boarding. Then just basic flight.

Flight details on public information screen were misleading and wrong.

Seats are very small, I’m not a big person, but the person beside me was using his seat and half of mine… and this person was a bit gross but not a lot…

all fine - did not have food - there was no entertainment

Long delay was made worse by lack of information and long time in queue waiting for the plane to arrive

How terrible! Extremely bad! I can not even wait for 5 minutes, because the Berlin airport does not work in the security facilities and can handle people. No communication, although we were assured by about 50 travelers that the airline is informed and is waiting for us.

Delayed delayed delayed and then cancelled very late not allowing for too much time to find a room for the night
