No it’s definitely different than past years. I travel this way everywhere including many short haul flights in Europe and I past years, Australia.
You can say they should not have allowed it in the past but don’t tell me how I traveled on previous Virgin Australia flights.
As for the rental car, I chose pick up in CBD Sydney and return at airport. Kayak didn’t show Domestic vs. International airports as different choices. Neither did all the other booking engines which Kayak returned.
