I've used MH several times to Australia, luckily at the front of the aircraft, and their product compares very favourably with other carriers - and usually at a lower price.
I did transit through KL just two days after MH370 and it felt a bit strange, but it didn't put me off flying with them.
They clearly need to restructure and that means cutting some less profitable routes, I for one hope they can turn the business round.
