Thanks for the reply.
I am registered as disabled for mental health problems. My carry on luggage was a little larger than the ticket, so, I was asked to pay a surcharge at boarding. This I am not disputing due to T&C.
At payment of the surcharge I was told that I could take my hand luggage with me and a label was attached to the bag.
On the apron, ground crew took my bag off me and then I realised it would be hold luggage.
On the flight I realised that I had important medicine in the bag and was worried that it might not arrive.
It did arrive but when I inspected the label it read that medicine and lithium batteries should not be packed in the bag. Also, there was a luggage receipt sticker that I should have been given.
I was disturbed for three reasons
1. Ryanair did not tell me that my carry on was to be hold luggage and I spent the whole flight worrying that it would not arrive as well as not been given a receipt. My medicine is specialized and can not be prescribed over the counter.
2. I have other Ryanair flights that I no longer want to use as they clearly breached standard security protocol by allowing power banks with huge lithium batteries in their hold. There is a reason why the label attached to the bag clearly stated no lithium batteries. I still have the label as evidence.
3. After reading the label upon collection I was deeply disturbed that Ryanair did not advise me as to what was written on the label and that I should have taken my medicine and power bank out and spent the whole break in France worrying what might have happened due to their negligence.
So, Ryanair did not show any duty of care and jeopardised the lives of not just me if my medicine had not arrived but the whole plane by allowing a power bank to be stored in hold without consultation before for a lousy few pounds.
I booked the flight through a broker, paid by credit card, so I did not make the purchase direct with Ryanair
