X-Centric has summed up life in Ryanair pretty well. Just to clarify one question from the thread starter
"take home pay £££ as an senior FO ?"
There is no such thing as a senior FO in FR any more. Sallary is about £23k plus sector pay about £15-22k PA. You will need 3000+ hours including 1500 JAA 25 to apply for command plus preferably at least one winter with FR.
