Daylight flight between LHR and LAX

Hi,
I am a practicing Orthodox Jew and wish to travel form LHR to LAX on
Friday 8 February 2008.

There is a BA flight round about 10am & a Virgin flight at 11.30am.
The flying time is just over 11 hours.

If I catch either of these flights I will arrive in LAX well before
the Sabbath commences in LAX. However, my Rabbi has said that I should
check on the route the flight takes as it may go far enough North to
actually encounter a time of darkness thus meaning that the Sabbath
has already "arrived".

Could you please advise if either of these flights do?

Unusual question but I think quite interesting....

Thanks in advance for all the help!

You can depart LHR on Friday anytime between 06.00 and 15.30 and still
arrive in LAX before Saturday.

WTF has darkness got to do with it? The Sabbath begins at 00.01am on
Saturday.

No, apparently it does begin at sunset on Friday.

Not in June. In the northern latitudes the sun doesnt set
until after 10 PM local time and youll be there around noon
local time

That is not what the OP asked. Did you actually bother to read the
post?

Maybe if you'd bothered to read the OP's post, you would have figured
that, in fact, this is not when the Jewish Sabbath starts.

If you're really concerned about international travel on a Friday,
switch your flight to Thursday, or wait until Sunday. Problem solved.

I took a BA flight from LHR to SEA on December 30th. It departed in
the early afternoon, and it still didn't encounter much in the way of
darkness. Your flight doesn't go quite that far north, and a little
on-line research would have shown that:
http://gc.kls2.com/ is a Great Circle Mapper. You will note that the
LHR-LAX route goes no farther north than southern tip of Greenland. If
anything, the 11:30am flight is most likely to be in continuous day-
light, but I doubt if there's that much difference.

Such flights might pass just south of Iqaluit (YFB). At this time of
year, sunset is at 14:35 local time, 19:35 GMT. (but some times, those
flight pass much to the south, depending on winds).

LHR-LAX is 4741nm. At 11 hours, this averages 431 knots (nm/h)

LHR-YFB is 2195nm. At 431 knots, it would take just over 5 hours to get
there.

LHR-YQR (Regina) is 3591 nm. 8 hours 20 minutes to get there. Sunset at
Regina is at 17:25 local, 23:25 GMT.

If you depart at 11:30, you would be flying over near YFB at about 16:30
GMT. Well before sunset. You'll be flying over Regina at about 20:00
GMT, still quite ahead of sunset.

Leaving at 10:05 AM from LHR, the northern most point for your trip would be
near Greenland's southern tip after about 1600 nautical miles (nm) from LHR
with an additional approx. 3000 nm to go. You would reach that point
approximately 4 hours after taking off from LHR with a 3 hour time zone
difference for an approximate local time of 11 to 11:30 AM. There would
still be plenty of daylight at that latitude of 60 degrees north. The Artic
circle is 66 degrees north which is north of this location and it would not
be a period of 24 hours of darkness at that latitude at this time of year.
The winter solstice having passed, the days will be getting longer at that
point in time.
