Coming in on a cruise to Brisbane. They usually get you off the ships by 7am and it's 15 min to airport, but to be safe I booked my flight to depart the following day at 9am (a330 to AKL). If by chance I got off the ship in time to make the 9am the day prior to what i've booked, and assuming there's space available, is there any chance they'd let me take the same flight a day early?
Booked in Business on BA Avios booking.
