Yes indeed , they fly to BRU , I think at about 3 times a week with B747
They closed the station and send their passengers over LHR Since that moment they increased the number of pax from Belgium .
Sofar as I remember they stopped after Thai and before SQ .
MH flew a few combinations I think there was KUL-DXB-ZRH-BRU and then later it became KUL-DXB-BRU-MAD or something similar.
They were operating Boeing 747-400s on the route and DXB wasn't as known by the general public in those days as it is today.
I guess a 332/78x KUL-DXB-BRU would make sense nowadays. But given MH's difficulties I rather see them trying to sustain their hub presences with this type of traffic rather than launching point-to-point. At least for the time being.
