I flew a couple of CO flights in May 2010 (TPA-IAH; IAH-TPA)
The flight credit posted in my UA MP account in 48 hours.
If you completed the flight on Monday (i.e. you departed the EWR on Sunday and arrived in HKG on Monday, you should have had you flights post by EOB Wednesday.
Your only option is to wait the 15 days and go to .bomb and enter your ticket and seat number for credit.
I suspect your miles will post today (Thursday, Oct. 21).
Also, are you sure that the class of service you flew earns miles ? I flew a P class on Swiss Air this May ZRH-MIA-TPA. The MIA-TPA was on CO. I did not receive credit for these miles even after complaining to UA.
Good Luck and let us all know how it is resolved.
