Hello all,

I learnt from the BA website that Executive Club Members can collect Avios when travelling on China Southern Airlines flights. Does that only count when I fly BA with a connecting flight by CZ or can I use my Executive Club number when booking a flight that is entirely CZ?
I am looking for flights from LHR to SYX.
If I book from the BA website, there is a few hours stopover in PVG and then I continue to SYX with CZ. The problem is I want to collect my luggage at PVG and then spend a few days in Shanghai. Can I still accrue Avios for both if I booked the LHR-PVG flight on the BA website and a later PVG-SYX flight on the CZ website? Does CZ allow you to provide FFNs aside from their own?
