This is another one of those that requires a ton of time in coach and and overnight in HKG plus if you don’t live in IAH are you have to position there as well. However, if you can make this one work for sub $800 you are talking only 40,000 FlexPerks points to get this one thus max out of pocket costing no more than $200 from IAH in airfare for a TON of MQMs. Here are the numbers with a HT to FT on this one:
17,663 MQMs at 3.64.5 CPM
Bookable on Delta.com
DM yields a nice 39,742 Skymiles per CWSI.net!
No visa needed just to visit HKG btw.
