well, to start with roster, it's very simple :
about 15 on/15 off....sometimes more, sometimes less, but average it'll be 15/15
And of course, due to 15/15,.......no leaves
for the base, you're assigned with your pax, who 'll your boss for all time, that means you'll be base where he lives, and global pay you tickets from your home, to his boss' sweet home..
for the payscale, depends on your a/c and left or right seat !!!
oh , forget this, all training, and medical check are scheduled on your day off..
are you going for Capt, or F/O, and which aircraft ??
take care mate
