Same as you get now, except the A319s are blue and white and you don't get a predictable roster. There's a preference bidding system called Carmen which is almost not worth using. Once again, seniority wins but there's not a lot in it between junior and senior. The only positive of note is that once your roster is out, it's effictively set in stone.
If you're not interested in LH and have a command in the immediate offing, for your own good stay put.
