It's been a while(couple years) since I took this trip, and luckily for me my GPUs cleared back then - but wanted to check and see how things are today. As far as I know, I have two options - ORD-NRT-SIN, or ORD-HKG-SIN. From my previous investigation two years ago, routing via NRT had greater chances of upgrading, which is why I chose it back then. Wanted to check and see whether that is still preferred. My ORD-SIN leg can be Fri or Sat departure, and my return is on Friday.

Thanks a lot in advance for the latest up-to-date advice.
