Is there any way to force the search to show flight availability results for the BA (PEK-LHR) + BA (LGW-DBV) routing? I am using the "Flight Availability" option with Airline=BA and Connection=LON for the route PEK to DBV, and with the departure time set to around the time of the PEK-LHR BA flight, but at the moment it only throws up the CA (PEK-LHR) and BA (LGW-DBV) routing.

Both involve an overnight connection - just seems a bit odd that the "all BA" route isn't picked up (there is certainly a through-fare on this route). If I select the Oneworld alliance option and then take out interline connections the results show me various routings via HEL or DME but not the BA routing through London. Not a huge problem as I can search for each separately, but certainly a bit mystifying ...
