Needed to fly from BKK-CMB but wanted to try out the SQ F lounge at SIN T3 so managed to get the ICC to book an award ticket for me BKK-SIN-CMB on SQ F.
SQ dropped F from the SIN-CMB route and it looked like I was going to have to miss out on that lounge and fly SIN-CMB in C instead.
I knew I was trying my luck and was more than ready to be laughed at and told to get lost but I rang the ICC and they were happy to route me SIN-BKK-CMB on SQ F and TG C. Thus making my 'one way' routing BKK-SIN-BKK-CMB!
