Assuming both flights are on the same ticket, you will see both flights on OLCI 24 hours prior to BNE-DXB flight.

If they are separate tickets then you'd still be able to check in for the DXB-LHR flight while you're in BNE. Besides EK staff at BNE will be happy to assist with issuing the boarding passes for both flights and checking through your luggage anyways.

I think you might be reading too much into OLCI!
