Farthest I've driven: London to Biot, France - 850 miles, basically a bit farther than Beaumont to El Paso with a ferry crossing thrown in.
Farthest I've flown: Houston to Tokyo non-stop (6,665 miles), then on to Seoul.

The non-stop flight to/from Tokyo was 14 hours, which is enough time to eat, get drunk, pass out for 8 hours, wake up and still have 4 hours to go. It was also the worst jet lag I've ever had.
