I am usually a leisure traveller and do not have to work while on long haul flights yet I have a lot of compassion for those who do-kudos to all of you. I could not do that on a regular basis and would love to know your secrets for long distance travel.
I try to plan my travel in Business or First on FF miles usually.
Not with standing, I try my best to only sleep on redeye flights departing the US after 9pm-will eat dinner before and put the bed as flat as I can after takeoff.
Westbound back to the US-usually a good book and some movies.
