In the last week or so, CO released tons of R seats to Asia (HKG/PEK). Up until then there were Zero R seats after May 24. If you ever wanted to buy an H ticket and upgrade to PEK (~$1,500) or HKG (~$1,600) now is the time. Last I checked theay had released avaialbility thru September 30.
This has been a sore point with several of us who wanted to buy a ticket and upgrade rather than use miles, yet, while there were plenty of standard award BF seats available June thru Sept, one could not buy a seat and upgrade on the spot. Hoepfully, this has been fixed going forward and when BF award seats are released, R seats should be available at the same time.
If you have availability of the KVS tool, you can monitor R availability as it becomes available.
