Hi,
I've got a crazy itinerary soon on oneworld (booked via OTA, Malaysia Airlines ticketed).
Outbound is PNH to DFW (via KUL, NRT)
I'm returning DFW to RGN (via HKG, KUL - DFWHKG with AA, HKGKUL with Cathay, KULRGN with Malaysia)

I'm needing to get to RGN asap and have just dicovered a Dragonair flight (also oneworld) HKGRGN direct (ie not via KUL) that gets me in many hours earlier than my booked ticket.

If I book a redemption seat on this dragonair flight, will the agent in DFW allow me to check my bag only as far as HKG? Or will they let me check through to RGN but on the dragonair flight?

I suspect both will be "no" and I'll have to waste several hours travelling, but thought I'd ask and see if anyone had any experience of such situations.
