Update: No plans, not gunna happen unless they knock down the present terminal and start again. Airport owners either charging Virgin too much for the floor space, or Virgin too stingy to look after their HBA pax. Or both.
The owners (majority related to Macquarie Bank) have nickel-and-dimed HBA for years; arriving and departing pax still have a walk on the tarmac for
up to 250 m to/from their planes. The Feds recently under-wrote a lengthening of the runway and the owners have .... increased car-parking (that ever-profitable side-line).
Oh, and no permanent police presence at HBA (no Feds and only occasional local wallopers. You see, nothing bad will ever happen at HBA
