SQ definitely daily 772ER from Winter schedule. This is more than welcome as the flights are rammed at the moment.
They have put in an official request with HQ for a second daily flight 3 times a week, preferably Friday, Saturday and Sunday. The problem is lack of aircraft caused by selling 744's and then not getting A380's on time and also other destinations are chasing additional flights as well. They're are 'on the list', so keep your fingers crossed.
A Friday afternoon/evening flight to Changi would be fantastic for me personally.
