sorry for the double post and pushing this back up, but i feel like my last question is still unanswered...

Right now I was looking at my online reservations page on UA website and the following is on there:

Hong Kong, Hong Kong (HKG) Singapore, Singapore (SIN)
Flight Depart Arrive Cabin Seats
United 0895 HKG 08:00 PM SIN 11:45 PM Economy (T) N/A
Flight: Confirmed Thu, Feb 24, 2011 Thu, Feb 24, 2011

Singapore, Singapore (SIN) Hong Kong, Hong Kong (HKG)
Flight Depart Arrive Cabin Seats
United 0896 SIN 06:40 AM HKG 10:20 AM Business (Z) N/A
Flight: Confirmed Thu, Mar 3, 2011 Thu, Mar 3, 2011 Select seat(s)

Hong Kong, Hong Kong (HKG) Singapore, Singapore (SIN)
Flight Depart Arrive Cabin Seats
United 0895 HKG 08:00 PM SIN 11:45 PM Business (NC)N/A
Flight: Confirmed Thu, Feb 24, 2011 Thu, Feb 24, 2011 Upgrade: Confirmed


So question is: After I upgraded at the Airport, the upgrade was confirmed online, but the old fare was still showed. Also the cabin class on the 1leg is NC... which honestly I have no clue what thats supposed to be.

On my inbound flight the cabin class is confirmed to be Z - in this case I should accrue the 200% mileage rate?!

thanks in advance!
