Wasn’t Malaysia given a rap over the knuckles in the recent past for regularly not having minima when flying in to the UK?
I belive they received a ban from UK airspace for about 18 months. It was no huge surprise to me; I'd previously been a passenger on a flight with that airline from LHR to KL, that couldn't even reach that planned destination and had to divert to Penang. That was in good weather, let alone fog at the destination.
