It was suggested on Airliners.net, could they not op to somewhere else more sustainable, because LHR has 2 A380's and 1 77E every day from MH/BA which is risky for those two in itself. D7 would most definitely lose out.
The suggestion was x3 weekly DUB, however I thought that MAN could work better 3/4 weekly. Either that or operate both, x3 KUL-DUB-KUL, x4 KUL-MAN-KUL or even x4 KUL-MAN-DUB-MAN-KUL
