I am flying Jetstar BNK-SYD and on a separate ticket FJ SYD-NAD. The FJ metal flight is codeshared with Qantas. Am I likely to be able to use the transfer bus at gate 15 of SYD T3? Although a codeshare, I booked direct with Fiji and not with Qantas. I have read conflicting reports about transfer bus potentially being available to all codeshare flights and even One World flights. I have 1h40 minutes to connect, any chance of transfer bus agent taking pity on me in the scenario where I wouldn't normally be allowed onto the bus?
