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.

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

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

The Ryanair staff was not polite. We all travelled with the same suitcases as we departed from Thessaloniki, however they decided that for some passengers the suitcase was not the rigth one as far as the dimensions are concerned. Furthermore, one air stewardess asked passengers to close themselves the luggage cabinet in order to prove that the lugagge was not properly fitted, which i think is very unkind and unprofessional. We also had to wait outside , some metres away from the plane until last passengers came off....It was generally a dissapointing experience.

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.

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

A normal Ryanair flight = too many announcements to sale something, hard landing. Otherwise, good value for money

Toulouse Alicante, excellent. But the 2 next fligth by Air Europa canceled. Bad bad

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