Guide passenger if fhey board from front or back door cause it was a total mess

I liked almost everything (e.g. ease of booking, price, punctuality, efficiency, friendliness, courtesy). A slam landing in Dublin airport took some of the gloss off it, though. Being able to paste here the text of the review of the same flight that I just wrote for Ryanair would make me feel better about Kayak too.

Delay in boarding with no explanation why. Stood for about 40 mins waiting to board

Rubbish moved my seat don’t know why same seat configuration cost me extra so me and my wife could sit together now I know why no paper ticket so they can do this

Flying from Newquay was an absolute dream! Would 100% recommend flights from there!

From boarding to disembarking, the whole operation was very efficient.

Passengers next to me insisted I change seats so they could sit together. I had to frequently move so that when the sear belt sign was on I was in my proper seat! I was returning from helping my mum with my dad's things after his sudden death and didn't feel like arguing with the other passengers.

They were extremely unprofessional and unhelpful at check in. They did not understand laws related to Spanish residents flying with family It was very discriminatory the way we were treated.

They boarded us but somehow did not manage to record us boarding, so rather than check if we were onboard they removed our bags from the aircraft. I got a call from Ryanair staff in Dublin when I landed in Madiera asking me where I was!!! When I said I was in Madiera I was told what had happened. Our bags were to be sent to Madiera the next day via Manchester, they didn’t arrive. They are now due to arrive two days before we leave. I don’t see myself using Ryanair again unless I am forced to and even then I may just refuse.

Flight was over an hour late. Boarding was really messy with long queues at the plane.
