Here we go again with the whinge fest about Air New Zealand's prices. 

I get it.  I try book the same flights as everybody else and when you're trying to fly some obscure route from this province to province its gets expensive. Quickly. 

But here we are again with politicians telling us fibs - telling us they can wave a magic wand and fix all of our problems. 

This time is James Meager - going in to bat for the South Island. He says flying shouldn't just be for the rich, the government is going to take action and is talking about underwriting airlines.

Do we want the government underwriting the purchase of turbo prop planes? Really?

We've heard this all before of course. They've gone after the banks, the supermarkets, and the price of petrol. 

I can't tell you how many painstaking and frustrating interviews I've done with ministers of all colours and stripes who swear black and blue they'll sort it out and then don't.

What's worse? The person that punches you in the nose? Or the doctor that says they'll fix it when they know you can't? 

Here's the thing, if you wanna book the main trunk line, it's relatively inexpensive, providing you're not booking last minute. There's Jetstar keeping Air New Zealand honest. That's competition.

But if you're flying Kerikeri to Dunedin tomorrow, guess what? It will cost plenty. Why? Because they've got you over a barrel. You need to fly. It's short notice. 

8000 people live in Kerikeri and 130,000 in Dunedin, these routes are often empty. 

The fact is running a profitable airline in a sparsely populated country is bloody difficult.  And we want them to be profitable, otherwise we have no airline and we're a backwater banana republic. 

And the regional players - they're no better off. Air Chathams the other week was threatening to pull out of Whakatane unless the council paid for a new Cessna. 

Everyone compares us to the Australians - but have a look at outback Queensland. You pay thousands just to get to Brisbane. 

Show me a headline about flights being cheaper from Dunedin to Bali than Dunedin to Auckland and I'll show you one about Mount Isa to Brisbane and Brisbane to Canada.

Population matters and guess what? We're a blip on the radar. And as for the promise that some politician will swoop in and save the day - it's about as reliable as planes.
