Burnie5204,
The apron improvements I refer to related to a planning application (Dec 2011) for ground level covered walkways. As my business no longer takes me to the airport I don't know if these were ever built?
As you suggest, going back further, there were also plans for an extension to the elevated walkway to the arrivals hall, thus reducing the number of bus transfers required; the plans also included provision for the addition of airbridges at some future date.
I assume finances and reduced passenger throughput have seen these plans binned?
