Smooth journey made good time. The aircraft was littered and did not look very presentable.

Smooth journey made good time. The aircraft was littered and did not look very presentable.

On time departure; arrived early into Faro. Air Malta operating flight, crew friendly and efficient.

I didn't know that all connecting flights require online check-in two hours in advance, so I was fined 55 euros. This is a lesson learned.

There isn’t any entertainment. The food and drink was available for a price. I didn’t buy any.

It would be nice to have power to charge phone.

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.

Well... Our flight departed with more than 3 hours delay from Beauvais.

I haven't had a ok flight with Ryanair in so long!

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

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
