Will be returning home to Adelaide from Ho chi Minh in late January flying Y, the wife and i were thinking of treating ourselves for the SIN-ADL segment and using cash to upgrade to J if there are spare seats, where would be the best place to to this?
Check in at SGN or the transfer desks at SIN?
I am already guessing that there wont be any free seats being the end of Aussie school holidays but thought it worth the question
