I try to do the same thing, except I'm continually fighting flight attendants that insist all the cabin windows be closed and dark for the entire span of the flight, so they can then flip the cabin into full blasting sun and overhead light 90 minutes before landing when the breakfast service begins. I shoot for a window seat and try to crack my shade a bit, just so I can get morning sunrise light as we cross over. I realize this darkness is what the majority of the passengers want on their eastbound transatlantic flights, and I'm sure the crew wants the passengers asleep and inert over the 4-5 hours, but IMO that just generates more jet lag than less. They want their sleep NOW even if it means screwing up their sleep for the next 2-3 days.
