Likewise - only on SQ from SIN to SYD last year. A daytime flight and a whole F cabin in a 777 for just me and Mrs Qwest. The service was amazing and we had BA to thank for it - they cancelled our flight and put us on QANTAS who cancelled and moved us to SQ. The best thing was we were on BAEC points and an Amex 2-4-1 and SQ gave us both the points for the flight into our Krisflyer account.
