Contract captains as far as I am aware do not have allocated bases . They might fly 5 days from PIK , then 5 days from NYO et c. There is an opportunity to apply for a prefered base via company's WEB site but I do not know if it works .
Some people like this system . I even know some RYR captains who would like to change to conract . 5on/5off roster for many seems more attractive .
