Have just managed to upgrade our J Avios Companion Voucher booking to F on the way out all the way to SYD! I can’t quite believe 2 F seats appeared in the very day we are travelling!

2 questions I am hoping someone can answer! I may have more when it sinks in!

Does an F ticket open up any opportunities for different/better Lounge access in Singapore, we have only blue status?

Upon arrival we are then catching a Qantas J flight to Wellington. We have 4 Hours 20 mins so cautiously optimistic we will make our connection. The question is does our inbound F flight give us access to a better lounge while we wait?
