Thank you for your response, that was exactly what I wanted to know. I guess I'll play with some "dummy" dates and see what kind of seats are available or I will exlplore other redemption options. I'd rather not go via Singapore again as it's much longer, but I may not have many other options. BA has a new route from Gatwick in Biz only, but I highly doubt they would have anything available as the route is brand new and they are at capacity this Christmas already.
