seems to offer a flight in 2010 which leaves Boston at 8:15 am. Then
you arrive in London Heathrow (LHR) at 7:45 pm local time the same day. In this way,
you don't have to sleep in the airliner. Its with a Boeing 777-200ER
and it takes 8 hours and 30 minutes. In 2011 this seems to be flight BA0238. The advice is to get up real early,
but stay awake during the short day. As once you arrive in London, you
need to go sleeping at an earlier time. The advantage will be that you
don't feel a jet lag during days after your eastward transatlantic
crossing. There seem to be few flights like this to Europe, but there is also one with United from Washington to London. British airways and American airlines also offer this kind of service from New York.
