Well my actual routing is LHR - CPH on SK; CPH - BKK on SK, BKK - HKT on TG. Return.
And yes I'm coming round to the same conclusion where to deposit my miles boddingtons. The problem for me is that I have had PPS status for seven years with SQ and so I'm only three away from Solitaire. I'm not giving that up, so with a bit of juggling I'll keep it and Gold here.
