How does the FAA get involved in regulating flights that originate and end outside the U.S.? The author states "I have been asked to sit on 14-hour flights from the UW to the Middle East, only to then fly the same aircraft to Asia on another nine-hour journey"

That means ferrying the pilots as passengers to location; at which point they become pilots for the next leg. It's still shit. It's bad ergonomically, it's very dehydrating, and you're getting a higher dose of cosmic rays. https://www.cdc.gov/niosh/topics/aircrew/cosmicionizingradia...
