We'll be arriving at MEL from LAX, in the morning on a Friday (on an award ticket). We would like to fly right on to SYD. Does it make sense for us to plan to buy our ticket at the airport when we arrive? Any thoughts on what price and availability will be like? Or does it make more sense just to book the SYD flight in advance with a large time buffer?
The reason we're considering this is that flight stats says our flight from LAX (on UA) is often significantly delayed.
