You’d have to sit in business class, if it’s a 19-hour flight. I did the 14-hour flight from Dubai to Sydney last fall. It requires a lot of patience.
Family is contemplating doing one of these x-teen hour flights and we are seriously evaluating whether this can be done without climbing the walls and begging for mercy.
I did Kuala Lumpur to Frankfurt. Qantas. COACH on 747.
Brutal but had to meet a timeline.
