ROSTER: Depends on the base you are in but most bases are 5/4 all year round. Floating pilots are on a 5/5 roster.
BASE : Could be any one of approximately 70 bases but generally the ones that are usually short of crews seem to be the southern Italian and the Moroccon bases.
PAY : Depends on the contract you are on, Ryanair , Brookfield or Storm.
HOTELS : Pick the one you like because you pay for it yourself with the out of base allowance you receive.
POSITIONING : Jumpseating is a privilege granted to flight crew and is free to use for work related purposes. There are rules so follow them and there is never a problem.
There is always a lot of bellyaching goes on about Ryanair on PPRUNE and yes, it's probably not for everyone but all things considered it is generally a nice place to work. Crews are friendly and professional, training is to the highest of standards, the roster is stable and the pay check is in the bank on time every month. Hope this helps.
