I want to confirm with someone to see if CO is cheaper than UA to fly from US (ORD or JFK) to HKG via TATL ?

I am intended to fly F, and CO come up the result is 70K each way no matter TPAC or TATL. I know UA is always 70K each way thru TPAC, and TATL is at a higher amount 85K each way, which come up to 140K TPAC and 170K TATL.

Is it still true with UA ? If so CO is the way to go ? I have linked both UA and CO account, if CO is the cheaper way to go, will certainly transfer my miles from UA to CO.

Also currently I am 1P at 76K, which also means I am CO Plat. Is CO the way to go to use miles anyway since CO Plat I don't need to pay all those award change/cancel fees, close in booking fees, phone fees ? I know only UA 1K exempt from all those fees currently. (not til end of 1st quarter next year the new UA status premier platinum will also exempt from all those award fees)

Last question, if I use miles on UA or CO, would a routing like ORD/JFK-FRA-KIX/NRT/ICN-HKG or ORD/JFK-LHR-BKK-HKG over the MPM ?

Thanks.
