They need to check-in at this gate? Why would Virgin not check them in from their first port of departure?
Thats one for DJ to answer, however by not handing over a BP at initial check in (bags are through checked) it does allow them more flexibility as was the case reported here, to the disadvantage of the passenger:
Domestic check-in connecting through Sydney:
Guests check-in at the domestic port, where their bags will be checked through to their final V Australia destination. They will also receive a transfer wallet, which contains a map of the transfer port and a bus pass to use in Sydney.
Upon arriving in Sydney, guests should head to the transfer lounge at Gate 37, where they can check-in for their international flight. Once they have received their boarding pass for their VA flight, they will be shown downstairs to the transfer bus, which will take them over to the international terminal. ** If issued VA boarding pass at the transfer lounge at Gate 37 then guests are not required to check-in again once they arrive at the international terminal.
Domestic check-in connecting through Brisbane:
Guests check-in at the domestic port, where their bags will be checked through to their final V Australia destination. They will also receive a transfer wallet, which contains a map of the transfer port and a bus pass to use in Brisbane. Upon arriving in Brisbane, guests should head to Gate 39, where they check-in for their international flight at the transfer desk.
Once guests have received a boarding pass for their VA flight, they will be shown downstairs to the transfer bus, which they catch over to the international terminal. ** If issued a VA boarding pass at the transfer desk at Gate 39 then guests are not required to check-in again once they arrive at the international terminal.
Domestic check-in connecting through Melbourne:
