Luke,
BAC Express and Emerald are 2 separate companies. Streamline doesn't exist any more ie as you know, been merged with Emerald.
Emerald aren't running any more TRTO's untill the hold pool has been emptied. I think it's currently at 10 or so.
Emerald/Streamline are still losing captains to other airlines at the moment. I daresay, they'll start to lose FO's very soon too.
