It all depends on where they place the Q400's. There's only 6 to go (at this stage) and 3 of those are marked to go West with Eastern crew (at this stage).
BNE at the moment has a fairly big supply of FO's so I wouldn't be surprised if they slow the recruiting down later this year.
Given the current situation with the engineers, any expansion in BNE would be a gamble. Alliance doesn't have too many spare F100's to take any more of our flying!
