I may living in another country but im a Kiwi through and through from Dunedin.
There was something in the ODT (digital edition) a while ago when all the fog closed Wellington, Christchurch and Dunedin on Weather effecting air travel and NZ. Interesting read, gave facts and figures about how often each airport is closed on average from fog and how many millions of dollars it costs to have weather effect Air NZ's operations. So if you were implying i pulled that from my ass you were wrong.
John, i kind of understand what you are saying compared to other airports in NZ Dunedin has a great setup even if it is only with NZ and SJ. Hopefully we will see someone else setup soon. QF might even do alright out of Dunedin??
