very confusing. Are you going to TPE or HKG? If you transit anywhere in China besides HKG, you need visa.

If think you want to take DTW/NRT (nonstop DTW is coach only) You might make the cut on ATL--what's your status?
I see DTW/NRT 12th, then connect to HKG next day as best.
JFK to NRT is wide open.

We have zeds on Hong Kong Express but: We fly UO but not HX (unless codeshare w/UO).

try whichbudget.com for LCC's

PS--Macao to TPE?
