OK I just spent 10 mins with IFM discussing rosters - I have a few things to report:
1. Crew Members have ZERO input into roster positions. Roster is generated by ICORPS which is a very complicated algorithm taking in many factors when setting rosters - Crew Training / Experience / Cabin station reqs / Length of flt- a whole bunch of criteria.
2. Once roster set crew members may ‘swap’ an assignment if they can find willing equal replacement.
3. Overall the only ‘non preferred’ destinations across the board are Jo’burg and ALL Indian ports
4. Preference for long haul v short haul assignments totally dependent on Crew Member - think marital status / study ( yes many Crew members also studying) / o/s family r/ships / many many personal preferences - yes greater financial allowance for extended journeys
5. Australia is one of the more desired destinations because of AU way of life / prices for goods in Australia esp food cheaper than Sing - safety on the streets - food offerings - IFM himself said his preferred dest esp ADL and MEL - rarely had he ever heard Crew not desiring an AU assignment
So make of that what you will - or not
