We arrive on flight from Durban. We will transfer from Domestic Terminal to check-in at the International Terminal for a Qantas flight to Australia. The flight is Qantas QF64 departing at 16:35. We will have 2 cases max 23kg and 2 hand cabin luggage (small cases on wheels). My wife is 68 and I am 72. Normally we can manage with our luggage transfer etc, except on this occasion I would have had an operation to repair a tear in my shoulder, and wont be able to lift luggage off the conveyer on arrival from Durban, and push the luggage all the way to the check-in desk at the International Qantas desk and lift it onto to their weigh scale.
From there we should manage with our 2 hand cabin luggage and will have to ask for assistance to lift the hand luggage into the overhead storage.

Are you able to provide assistance for this?
How much would this cost?
