Well i did say it was just a thought..
And yes you would get experience from any airline but getting in without any, as you implied in your original post, may be difficult.
I am not cabin crew and was unaware of the cost for training that you state (a quick look on the Ryanair website shows no mention of this) so all the the advice that was offered in my previous post was just that... advice
If you don't want the advice people on this forum have to offer, why bother asking?
Good luck in your future career, for what its worth you already seem to have the right attitude to fit in well.
