- admitedly it was in First....
but a 6am flight from BOS
with a 9am departure from IAD
. I had been up for several hours by the time I got to Logan.
By the time I landed in London, my body clock was telling me that I had been up for hours, would have been mid afternoon in the US.. but I was tired and it was dark in London. Went to bed, got full nights sleep and woke up the next morning feeling great.
I don't ever want to take a night flight heading east again, unless I am in the UA
