They don’t deserve one star. It should be zero. I had the worst experience with them. I only had a small bag and had no problems getting on the plane in the UK, no one said anything about the bag. Then when I was coming back from Berlin I was made to feel like a terrible person with two people bullying me, saying my bag was too large and demanding payment. This is despite the fact that they had already let people through with similar sized backpacks. I felt victimised as a solo female traveller and felt the only thing I could do was pay if I wanted to get home. The behaviour of the staff was appalling, and I wouldn’t recommend Ryanair to anyone. Sometimes it’s not about the money, it’s about customer service and decency, none of which I received from Ryanair in Berlin. If they provide good service it might be different matter but this is the worst service I’ve ever received.
