Thanks for the reponses to my OTP-PHX query. In the end we have put together an interesting 1280 tier point Asian tour @£1.70/TP (good value for travelling East I believe). So our November trip goes OSL-DOH-PEN-KUL-CGK-CMB-DXB returning back to ARN on QR (359 & 788), MH and UL, plus positioning to OSL and back from ARN.
Appreciate all the great ideas and wealth of assistance on here.
