Hi everyone. Me and my fiance will be on our honeymoon in Aug. I have booked a return flight from HK to LAX on PEY with R fare for 8/24/14. I've requested to be upgraded to business, however, are being placed on the waitlist in the mean time. I checked and it seems business are all wide open... any reason they cannot accommodate the upgrade now? Also, what would be my chances of getting the upgrade cleared?

TIA
