not done a 380 yet but did VS 789 LHR-MIA and got off after almost 9 hours fresh as a daisy and not jet lagged
unbelievable effect of a better well being after a long haul flight
landed 2pm USA time (early - got to try and stay up until 9 or 10pm) rented a car drove OK to FLL hotel - unpacked went out for nice dinner and slept until 7am
