I am looking at some flights between BKK and SDF in Y which are pricing up near enough the same whether I book via AA or JL on either codes and either ticket stock. I would be using my BAEC Gold status on the PNR.

Since both offer Gold Avios bonuses, am I correct in thinking it doesn’t matter which one I book in terms of Avios collection? Is there any factor which would mean I should try to book on JL rather than AA, or vice versa? I also have a choice of either metal depending on the exact routing (first to Tokyo and then via ORD/DFW etc AA gateways).
