Adding Extra Leg on Ticketed Award Booking
I currently have an award booking in J from HKG-SFO on CX892 and would like to add a leg from KIX-HKG prior to the aforementioned leg. I see availability on AsiaMiles for 85,000 miles total whereas I redeemed 70,000 for my original booking. I have MR points I can transfer over to cover the cost. What would be the best way to add the additional leg?
