Have flown LGW/KUL both in Biz and Eco. on their B777 aircraft. The nearly lie-flats in Biz was nothing to shout about from LGW to DXB. Cabin Crew were friendly and attentive when required The sleeperetes from DXB to KUL were awfull and the flight continued to MEL....urrrgh. Biz Lounges at Gatwick and KL were lovely with Gatwick staff tops. DXB lounge unfriendly and staff cold and indifferent.
As for Eco. never never never never again. 10 abreast on a B777??? Gee Emirates, you can do better than that!
