On a side note if you are leaving the company there is an important thread and contact details on REPAweb for Brk pilots, if you follow that thread you might leave ryanair with far more money in your pocket. What are Ryanair going to do if you do not pay the "fine"? Sue your company? Which they forced you to setup and forced you to use their accountants, does anyone believe they want that to make it to court?
Useful post. In short: sign up to REPA!
