Recruitment on hold at the moment. My sources say November is when they'll begin interviews again. I think CVs are being accepted though.
Aircraft orders haven't changed although the deliveries haven't turned up this year as "promised" by the manufacturer. Should be a different story next year when the 4000's and the 7X's pitch up. 750's being delivered at last...
Buttie Box, bear in mind you may swap your -400 for an entirely different 400 altogether. If you can accept a possibility of no APU, no FA and no long haul and be an FO for a while*, you'll be fine.
* could be any where from a few months but more likely 12 months. It's performance and needs based.
