Asia mile - Multi-Carrier Awards

Hi Everyone, 

Planning a trip with my partner to UK from Singapore. Currently have about 230,000 miles and planning to redeem the Multi-Carrier Awards ticket which my Asia miles balance will allow myself and my partner to fly 10,001 - 14,000 miles (Zone 8) all business class. I am thinking the route " SIN-DOH-LHR-SIN" (total 13,883 miles) but just thinking does anyone has any ideas on any other routes I can fly to fully utilise the ticket? thanks in advance everyone

BA also does SIN-LHR, and later on QF will join too, no need to stopover in DOH unless you want to visit there.

thank you Michael
