Tried searching for a similar situation on the forum, but couldn't find it.
I'll be doing the following:
YVR-PEK-DXB on 1 RTW PNR with no stopovers
YVR-PEK on AC
PEK-DXB on CA

I am not actually stopping in DXB either but then going on to DXB-MCT-SLL on WY after an 8-hour wait (I have a room at the Dubai International Transit Hotel)

Since my checking in is through AC and not CA, will they be able to check in my bags all the way through to SLL? If AC can't, then can CA make changes at their counter in PEK? And if not, then can WY make changes at their counter in DXB (before baggage claim / customs)?

Now if the answer to all these questions is a no. Then how do I solve this problem -- I don't have a UAE visa to pick up my bags and then recheck ex-customs at DXB airport, so what would the arrangement be?

Thanks for your input in advance!
