Sorry - I'll be buying a cash fare for the ORD/HKG round-trip. I've only got so many miles (CX actually) and not enough for a long-haul RT to HKG, which on CX is impossible to book anyway.

Unfortunately, the cash fare on JL from RDU-HKG is over $1800 while ORD-HKG is about $1300. (Sorry - I refuse to fly the long-haul on an North American airline.)

I also want to stop over ORD for a little longer on the inbound anyway.. I priced it out in one single itinerary and adjusting the final ORD-RDU leg later by a few hours bumped up the price by another $100! So I've got another reason for this arrangement... again my main question is: will this be ok? Thanks a lot!
