But these are maybe around 10h max flights - given the range of ~4000-4500 miles. So you're still on a plane for ~5 hours.
But you still have the same issues with time zones. If you need a lot of time to adjust to a new time zone, you were always flying in way earlier - so whether your flight is 5 hours or 10 doesn't really matter much.
You were never going to red-eye in for a morning meeting in London or Paris either way.

I usually pay like 160eur/hour for top tier F products like the Emirates A380.
I just paid a little over 4000 euros for a 32h round trip with that particular offering. I don’t chase after deals, I just tend to depart from a city without many F pax.
Of course, YMMV.
I'm seeing MXP-HKG at 4000eur for a round trip, MXP-BKK for 3800eur. There are probably even better deals available if departing from some third world countries.
I guess you're from the UK, I'm seeing BHX-HKG priced at around 151GBP/hr. Shockingly, LHR-HKG looks even cheaper at somewhere around 100GBP/hr.
Though either way, even after a 9 hour business class flight, I'm certainly not ready to go to work when I get there even though I had a lay-flat seat.
