Malaysia Airlines never really got better after what happened. I finally stopped booking them a few months ago, I was never concerned about the two fatal incidents but rather I had enough of their joke of a website, it simply doesn't work at all on both mobile and desktop and I don't really see why I should spend more time trying to book a flight then the flight would take.
Their app crashes after the start screen. Enrich is dead, the last devaluation is so bad there is really no point in even considering to collect with them. They fucked up 2 of my bookings when they recently changed the reservation system, charged double taxes, refused to refund (in fact refused to accept it is a mistake to charge the same taxes twice), ignored my emails, ignored cancellation requests and much more. I booked all short haul flights for the next months with AirAsia, I rather sit in a low cost plane where I know what to expect than this endless fuck up from Malaysia Airlines.
As for the CEO choice, it does not get much more corrupt than Malaysia and I am fully confident with the new CEO the countries tradition of racial policies and corruption will live long at Malaysia Airlines (not that it somewhat decreased with the two non Malaysian CEOs).
