Hi. We are looking to book an economy saver flight from BNE to SIN on Fri Aug 23 in the afternoon departure and then spend the night in bed in SIN and the following morning we looking to book an economy saver from SIN to LHR on the 9 30 am flight. We know that if we book straight through the points reqd is approx 41K. What about if we stop? We are not flying back with SQ as we are coming back with MH from Istanbul (their flight is $513 at the moment which seems great!).
