Singapore Airlines Mixed Class Bookings

[aussieboozer]

I'm looking at booking BNE-LHR return with BNE-SIN/SIN-BNE in J and SIN-LHR/LHR-SIN in F. Easy enough on their website but I would like stopover in SIN on the return trip and can't see how to do this. Do I need to use a travel agent?

Just book multicity with 4 legs (BNE-SIN-LHR + vv); choose First from the first leg as you did with the normal return, and put the relevant dates for 3rd and 4th legs that allow for the stopover.
