Hello Flyertalk -- I've only booked AA rewards using AA miles. I have the opportunity to have either Cathay Pacific or Qantas miles via a transfer but can't convert them into AA miles that I know of. I want to book a trip to Hawaii on AA from DFW to Hawaii and am Gold on AA.

Are there advantages to booking this trip using Cathay Pacific or Qantas miles vs AA? Will I get my Gold benefits even if I book them via Cathay or Qantas? Are those programs doing friendly refunds on trips in case my trip gets delayed/cancelled do to covid or what not?

Thanks for the help!
