QR only gives 0.5 EQMs on most Y fares, JL gives 1 on almost all of them. CX gives 0 miles or EQM on most coach fares as well. For MNL-HKG-Thailand flights, you may just want to book an LCC as they can be MUCH cheaper than the OW airlines, but if you insist or can find a good fare, Malaysia is probably your best bet for earning miles, but avoid the lowest classes as those earn 0 miles/EQMs. Royal Jordanian also flies 1x daily between BKK and HKG, so check them out as well (again, the lowest Econ fares earn 0 miles/EQMs)

I would book JL if you are flying coach. For other classes, you can compare on the myriad of links I posted

EDIT: If booked through AA with AA flight numbers on your ticket, you will earn per their award chart at 1 EQM, except Basic Economy (which I don't think they have for Transpacific flights yet)
