flight delay was announced after passengers were staged to board the flight. Communication regarding subsequent gate changes was poor.

Although our departure (DUB) was slightly delayed we reached our destination (LBA) ahead of schedule. The price was very competitive too (around €100 return). Plus, the departure times for both legs were very good: 13:05 and 15:10, respectively. I gave a neutral rating for Food and Entertainment because I didn't avail of either.

Just pushing back from gate now. Boarded into fourth aircraft with 13 hour delay to scheduled departure. Crappy experience.

Straight forward checking as long as you have completed every single detail online, prior to checking day. Efficient boarding, seating is ok for a two hour flight. Fulfilledour travel requirements from Manchester to Marseille.

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

Speakers were blaring. It's like being in a Moroccan market and you keep getting shouted at with what's for sale

very delayed boarding; the crew started the service extremely late and everything felt like they didn't want to be there and do their jobs; the pilot changed her mind about landing :))))))))) and we spent 10 more minutes circling around the airport before landing, eventually!!! lack of communication = lack of professionalism. she could have said 'ladies and gentlemen, due to us having taken off very late, we have lost our landing permissions and we'll have to wait some more', but she chose to shut up. big mistake that reflects poorly on the airline and herself.

Loupé l'avion pas pu embarquer mon bagage en soute. Pas compris l'heure de fermeture.

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.

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