Cheaper than Perth in Scotland

School holidays do not usually impact me much except when I want to travel somewhere when they are on. As you may know, I would very much like to attend Swancon 36. The only problem is that Perth is a bloody long distance away with airfares to match. I got a promotional email from QANTAS today promising low trans-Tasman fares. I get a number of these, but they don't usually include Wellington-Perth. But this time they did and at a very good price - hooray. But then the small print. The cheap fares don't apply during the second half of April - school holiday time of course. Harrumph.

Before you ask, I have been looking at options - Air NZ, Pacific Blue, Tiger, Emirates (have I missed an option?). There are options that are a little cheaper with a significant convenience penalty, but nothing as cheap as that non-holiday fare. Y'know I think I'd have preferred to not even know those low fares existed.
