I'm sort of new to regular J. (though my first J flight was 11 years ago). My new job now sees me flying J international more often than not. Just ticked over to Qantas WP with 6 months still to go (thanks to AFF forum for tips). This has been a mix of QF J hard product to Asia (SIN, HK) and using FJ to the US. I see flying J for business as a nice perk and I actually respect my business travel more than when in Y which I hated as I got older. When I was flying Y long haul I would always fly during the day (on company time) and usually fly up a day earlier and the same returning. Now I try to fly the evening before I need to be where I need to be and the same in return. This way I'm working the very next day vs recovering. So in real terms, my productivity is much higher.
For the right price, J is IMHO how flying should be for long haul. Peaceful check-in, peaceful boarding, nice flight with good service and for me, no long lines for the toilets. I tend to consume a little too many fluids (mmm bubbles) pre flight, pre take-off, during the flight. I hate lining up for toilets. And I really hate the person kicking the back of my chair - oh that gets to me. Or getting on board to find no overhead space. Or an extra large person that spills over into my seat. The list goes on.
I've now booked the mrs & I JQi *Class at Christmas time as this seemed like a good product / price balance. So our personal life will consume a mix of low cost J-type products long haul (SYD - LAX or SYD - HKT or SYD HNL) and Y short (SYD - MEL) with the odd dose of JASA at the right price. The danager becomes the more we get used to J the more it seems the normal way to be. I will also look to spend all these points on a pair of J RTW in the near future. I look to maximise points & SCs but never go out of my way to pay for them, but I always look to maximise the benefit of getting them.
So, as many have said, a product is only worth what someone is willing to pay for it. And paying comes in many forms - time, money, health, ego, perception, the experience etc.
Happy & safe travels to all the AFFers.
