Jamie2k9,
Thank you for your reply, but if you look to Ryanair fees table, and specially to the ** on the bottom, it states clearly that spanish domestic flights to Canary Islands (which is my case) is excluded from the higher charge.
I called Ryanair but I couldn't convince the lady of my point. "No, sir... It's 25€." But that's not what you have in your website! "No, sir... It's 25€."
Argh...
