Just locked up IAH-IAD-SIN and return for $894 @ 4.14cpm.
Going out on the 22nd and returning 26th Jan, so I have a couple of short nights in SIN.
Have combined it as a side trip to LHR-GIG-IAH (stopover)-LHR for a 41,270 trip over 8 days and still comes out at only 4.8cpm, with the LHR-GIG rtn upgradable with two GPU's being a V fare.
