My children went to the same school as Sergei Brain’s kids and prepandemic, on an international flight he flew in economy with his kids vs using a private jet or flying them in first class. Very admirable since he is one of the richest people in the world, but something I would find very hard to do myself, to be honest.
To add to the experience, Auckland to Doha is possible.
The one upside to that flight is that the plane is going land fairly promptly, you can’t circle for too long after a 19 hour haul.
