Hi looking at booking a business class points flight for 4 people Cairns - Mel in early March, it shows availability on A330 flight just wondering what you think the chances are a A330 will actually operate the flight as don’t want to be bumped and given it’s not holiday period just worried they may replace with 737. Our last booked trip Mel-Cns was for 3 of us and got downgraded at the airport and don’t want to incur that this time!!
