Just try to stay awake on an overseas flight that last 12-14 hrs. Not possible.
In my experience, the US air fleet is the most disgustingly vile carriers in the business. US carriers allow matrons to keep working until they’re in, what, their mid 70’s?
Flying domestic is just like being locked in a toilet with a wild Buffalo. You won’t see such disrespect toward the passengers on competent and classy carriers like Air China or Phlippine Airways. Or even Aero Mexico.
I sleep for at least eight hours on those and I’m just fine. :)
TOTALLY possible.....did it on the flight fromSf to singapore..17 hours....slept not one wink. But our seatmate, AKBAR slept 16 hours straight. GREAT seatmate!
