SN, just look at the Hobart airport pax handling dispute, HBA wants to up this to $12
per pax, then there's the pax charge at the other end.
Sydney
charges $14.39 per pax for handling & runway charges. Melbourne
charges $9.21
Calculate the tech crew costs per seat for a SYD-HBA or MEL-HBA sector & compare it to the $20+ airport fee's. This is where the cost of travelling is, taxes & charges, not tech crew costs, even at 300k. Don't let them bluff you.
