My first post here after a long time reading your collective wisdom...

I'm currently waitlisted for a redemption upgrade from PE to business on CX251 (HKG to LHR) travelling 25th July. What do you think my chances are? I know this flight is usually very busy so it's unlikely, can anyone help me find out what the load is like?

For redemption upgrades, when does the waitlist expire? I'm just a lowly GR at the moment (although will be SL by the time of the flight), does that make a difference in my chances?

Thanks!
