Yes, I need 9 hours of sleep per day, ideally 10. Unfortunately, it is hardly possible to have this kind of schedule when your family are all morning birds.
I feel ya! 9-10 hours optimal over here too. New baby is making that impossible.
I'm also a 9-hour-a-day person. My partner is probably at 7, but gets up quietly. I can function ok with 7, but I'm miserable and much less functional with anything less. Up late packing and up early for a flight? Misery. But, though I won't be going again soon, I enjoy a lot of the aspects of flight and most importantly, I don't have to think much during.
