AA will not through-check bags to AS on separate tickets unless both tickets are on the same PNR. On the other hand, AS will through-check bags to AA on separate tickets, even if the tickets are on separate PNRs.
Interesting - thanks guv1976. I recall reading that before and will keep it in mind.
The more I'm thinking about it, the more I'm deciding not to try to jump through hoops to make this happen. If the owner will work with me to shift dates to match AA's available flights into SVD, I'll do that. But transferring through BGI will be painful enough I'll consider forfeiting my deposit if that's the only option. Just learned BGI requires the full blown RT-PCR for fully vaccinated just to transit their airport on the return. I was happily looking forward to my US approved eMed test and not dealing with clinics and appointments and stress once I got there.
