Due to long security check and no last call announcements from Gate staff, my family and 12 other passengers missed the flight.

Due to long security check and no last call announcements from Gate staff, my family and 12 other passengers missed the flight.

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

Letting people wait outside for boarding in the rain and almost 0 degrees for a high temperature destination is very customer unfriendly

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.

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,

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

I wouldn't like to fly with them anymore, I don't like their service, you can hardly take carry-on luggage because they charge you for everything, you can't ask for a glass of water, and the flight attendant tells you that they don't have any, that you have to Paying 3 euros for a bottle of water horrible, I don't recommend it, and they don't have anything low cost, because the plane ticket may not be expensive but what they charge you later for the rest, the flight becomes more expensive, it's the only airline that I don't like it so far, and I traveled a lot.

Boarding was chaotic, the gate changed 4 times and we took off 1 hour late

Kudos to the staff for their patience and professionalism. Next time, please stop serving alcohol to Romanian male passengers who are clearly not able to drink with measure. Appalling behavior.
