I have a trip coming up using two separate award tix, both booked through AA.

award 1: PHL-DOH on AA
Two different PNRs, one for person 1 in business and one for person 2 in premium economy
award 2: DOH-MEL on QR
One PNR for both people in business

Is there any way to link any of these tickets under a single PNR so we don't have to pick up our luggage at DOH and recheck it? Ideally we'd have the entire trip under a single PNR. AA Twitter, who are ultra helpful, said that can't be done, we have to leave it the way it is. I couldn't find these awards as a single award, I had to do the two legs as separate bookings.

TIA
