Maybe the situation will improve once the 787s and A350s arrive? SilkAir also has some expansion plans and if Scoot works out and 777 guys from SIA move over, maybe the slots will start opening up.
I am also hoping the recent Singaporeans-First policy will reduce or put a fullstop to pilot hiring from HongKong/India/Malaysia and open up more spots for Singaporeans.
I am hoping this happens in the next 3-6 years.
