Before they patch this hole I did manage to use it. Needed SIN-DPS-SIN, was going to use MR points to "pay" for revenue tickets on QR, but instead was able to get SQ tickets through CO - which were not showing available on ANA. Saved about $300 or 30,000 MR points vs QR and the return flight time is a bit better. My first reservation with a CO phone agent - very happy with the service. Transferring points from MR to CO also easy and instant. Excellent!

As I've said in another post I'll be crediting about 50/50 between UA and CO next year to retain both 1K and my newly comped CO Platinum.
