Emirates planned a daily flight from Los Angeles (LAX) to
Dubai (DXB) with a Boeing 777-200LR in 2010.
Flight EK 216 seems to leave Los Angeles around 4:00 pm and arrive in
Dubai around 7:45 pm local time. This is a next day arrival because you
cross the international dateline. But, it's a daylight flight as you
fly westward, although the flight will probably fly a very northern
route.
The distance of 13.336 km werdward against the jetstream, is had to
make with any jetliner in 2010, except the ultra long haul Boeing
777-200LR or Airbus A340-500. No other commercial airliners are easily
capable of such long routes, without a payload penalty.
