I mean that if it were a US Airways flight (assuming that they were to fly to Taipei), it would be easy to figure out the upgrade situation. But it might just be that I'm used to it. I've never used US miles to upgrade on another airline.
Thanks for your helpful info!
EDIT: Well, now I look at my reservation on United.com, and my 4 flight reservation appears to have 6 flights, two of which (the intra-Asia flights) are now in business class. Did I cause that, or did that happen automatically?
