fritzandsauce,
perhaps you should have a look at the SYD-ABX-SYD schedules for both REX and DJ for your answer! DJ are offering two return services daily at VFR rather than business sensitive times of the day (a morning service at either 0900 or possibly 0930 and a mid afternoon service at 1530) whereas REX (and EAA for that matter) offer four return services daily between 0635 and 2015. It seems that at least initially there will be plenty of scope to move many more PAX across the schedule spread and carry the bags within any existing baggage agreement, assuming of course REX decides to continue with the agreement after DJ commence ABX operations!!
