Roster is an electronic piece of paper which bears no relation to what you may end up doing, the kind lady in charge of crewing once sent out what she thought was a meaningful and well intended 'clarification' document setting out rostering protocols, it included the the line that "the company will not change your rostered day(s) off with less than 24 hours notice"
other than that 30 minutes call out time from standby, excellent expenses and salary in general, CP & FM (737) are good people, if your in then your in.
Very interesting flying, but not for everyone and certainly not like any other airline in Europe
