I've heard they are only bonding pilots who have JAR25 experience ie turbo prop f/o's and captains etc. For those without JAR25 experience then you have to apply through one of Ryanair's approved organisations and then fill out the application and then hand tons of cash.
Wish more people would be firm and stand their ground and not go down the SSTR route.
Glad I didn't go down the Emerald route.
