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

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.

Flying from Hamburg to Stansted was a nightmare if I have to be honest, the flight was due to leave at 15:50 and we ended up not taking off properly till 16:56. They really don’t have enough people doing the sorting of baggage where you get the sticker for your case before the security check, going through security was 10x more faster then the whole baggage situation.

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.

Cabin crew couldn’t be less interested. Cabin manager was the most arrogant and the rudest I’ve encountered in many years.

Good but both flights were delayed by nearly one hour making boarding tedious. We had to wait with no information

The worst flight ever. Sitting in plane for 4 hours delay and then they change crew. No water or food offered to any passengers including children in that time. Only 2 toilets out of 3 operating for flight with 200 passengers. Only enough food available for about 7 rows of seats depending where you sat you might be lucky. Cabin crew very unfriendly.

Unnecessarily delayed and remarkably inefficient boarding contributed to a significantly delayed departure. Seats/legroom astonishingly uncomfortable even by Ryanair standards (minimal legroom plus reinforced plastic seat backs ensure you get punched hard in the knees every time the person in front moves, and as a 6-foot passenger I had nowhere else to put my legs. Upon late arrival at the gate in Luton we were kept waiting another 20 minutes before being allowed off the plane. Both Easyjet and Wizzair are currently a better bet.

Awful as usual the air stewardess loved her own voice and would not stop talking on coms for 2hrs please please please shut up I can’t hear my headphones and don’t want to buy juty free
