I have a tough one coming up, due to the somewhat-novel (for flights of the general route) departure time. Flight leaves a little after noon west coast N. America, and arrives in Europe early the next day, so early it won't even be midnight the time zone where we left (and pretty much spent almost all of past 4 years). Been affected by jet lag the past decade that I've been flying to the point I love ship travel where there's many time zone changes.
Any suggestions for this flight time parameter? In the past for flights on similar routes, I've gone to sleep after the first meal (flights in the direction generally leave mid afternoon to mid evening which is more sensible) and I do better with late flights. Have a 6 hr layover before the short-ish connection to the final destination.
