Oh, man, what a flight! I definitely think going without sleep helps on long international flights (of course flying first class doesn’t hurt!) because I was too tired for even my basic take-of and landing fears! I slept enough during the 13 hours from Dallas to Narita to arrive alert enough to make it through immigration and customs with only tiny goofs.
I wasn’t awake enough to avoid one big problem, though, but it turned into a learning experience, more on that later!
Back to sleep, off to get the keys to my apartment in a few hours!
