Melbourne (and Sydney) are almost a non-starter with maxed out ATC for the terminal and a difficult management at Tullamarine, who closed helicopter parking airside and forced the new start
Air Melbourne to operate to a pad at the Mercedes Benz dealership on the approach road off the Tulla freeway. Which necessitated a vehicle transfer, and for anyone landing airside they have to pay for a Melbourne Airport vehicle to transfer their pax to the outside entrance to the Terminal where they join the check in queues.
Air Melbourne boldly attempted airport shuttles with 109Es, but ambition seems to have outstripped demand.
Then there is the odd thing such as baggage, often 2-4 items, way above the capacity of most helicopters used on such jobs.
Quite how Uber think that they can overcome these known problems (Sydney Airport isn't any better), let alone that of city helipads, will be interesting to see. Regardless of their 'White Paper' and discussions with politicians.
