umm, let me see. It’s a BA Board. A post about a QF domestic J booking. So I pointed out the OP will potentially have access to some great domestic lounges in various destinations (as BA only serves SYD anyway) , certainly by comparison to most BA lounges (we are on a BA Board here, can I politely remind you again)..... and possibly they can book 787 J seats depending on their route.

And thank you for your contribution to the OPs upcoming trip.
