As far as I know still ongoing.
B787, still seem to be struggling a bit to attract"suitable" candidates.
AFAIK 737 selection on-going, know of a few FO's starting soon, believe screening full for the moment, but I would assume ongoing as there is a rumour that 8 of next years planned new airframes will be delivered by APR
(I see a few new ones registered already) so, it seems they want to take perhaps more than the original 11/12 ? planned for 2013.
Cadets/SSTR don't really know, best check the website.
