Entirely play for me. I belong to a
worldwide community that organises regional get togethers. Wellington, Charleston, Brighton and Melbourne this year. I enjoy meeting my online friends in the flesh so much that I am happy to pay for *ONE4s a couple of times per year to attend these gatherings.
I generally try to arrange my travel to correspond to a theme, with a view to writing about it. For example, last year's travel was focussed around sites linked to US participation in WW2 (Pearl Harbour, Omaha Beach, Hiroshima etc), and there may be a book in the works. But that's optional.
I enjoy air travel immensely. Being on planes, in terminals etc is usually pure pleasure for me. The technology, the systems, the view - it's all fascinating to me.
However, the down side is that being stuck into an economy seat for 14 hours, or having a long transit in LAX T4 is pretty hideous - the glamour loses its edge when you are tired and uncomfortable. So the perks offered by high status and forward cabins make the whole thing more enjoyable. It's one thing to sit in a gate lounge for hours and hours, paying high prices for snacks and trying to find an outlet to recharge your laptop, quite another to relax in an airport lounge where the drinks and snacks are free, internet access is laid on and you can have showers etc.
The additional luggage allowances, the extra airmiles, the priority luggage, quick service on the Qantas phone, these are all useful things.
I spend several thousand on my travel each year. I can afford to spend a few more to get to SG or WP, which makes it all more enjoyable, even on the trips when I'm in the back of the bus.
For me, the travel is not just a means to an end, but a hobby in itself. Others restore vintage cars or climb mountains. For me, being ten kilometres up with a view out over the world and a glass of spiced tomato juice on the tray table, well, that's my idea of heaven.
