Rikki
You would probably do your line training on the 45euro rate, not sure how many sectors you would require having JAR25 hours but say the normal 70 rate to be safe, after that you would go on to the higer rate of 85.50Euros an hour for greater than 1500 Jar 25 hours.
but I suspect that because you wont be a cheap option as F/O for the company for the normal year + you wont get the job! I hope I am wrong there, but Ryanair is a money making machine and as there not short on 250hr applicants that will be cheaper for longer I dont see you getting a look in.
I really hope I am wrong, Good luck.
