The science behind Qantas' bet on 20-hour flights

Light on the science, High on sales talk. Unless I seriously misunderstand things, the "faster" end to end travel time has no real impact on the jetlag problem. It's only 2-3 hours and the "sleep management" aspects could be applied to existing routing anyway.

This seems weird when we have ferry, train or bus rides that can take days or even weeks. I get that planes are special in their ability to cross timezones and so warp the usual day-night rythm. But that doesn't seem enough to make this a completely novel problem. Is there something else that makes this unique?

Give it a few years, I’m under no illusion that when faced with competition Qantas will ditch the wellness zones and extra legroom.

London-Sydney is only a bit further than London-Perth.
