Hi, I'm currently wondering on booking tickets on the following routes and I'm wondering if its possible to check-through bags (Just so I can decide on flight times)

AA YYZ-DFW booked with AA

CX DFW-HKG booked with CX

Both those routes will have different booking references and therefore normally I would need to pick up my bags at DFW during the transit. However, AA and CX are both part of oneworld, so I'm wondering if its possible to check my bags through?

Thanks all!
