I don't know yintsinmeritem, I used to do quite a bit of long haul business travel for a few years. One trip I've made a few times is Dublin-Heathrow-Singapore- Auckland-Wellington. When you throw on the connections to/from the hubs, eliminating any stopover starts to look that bit more appealing - on a journey that length, sitting around airports isn't much better than sitting in an airplane.
Having said that, I'm not too sure about doing it in Economy but then again I'm 6'2" so the thoughts of 2 hours, let alone 20, in an economy seat gives me nightmares!!!
