MH had a truly awful year that year, but it's hard to blame them for MH370 and certainly not for MH17. Besides that, I think their track record is on the better side among global airlines.
Yeah, Malaysian is not a bad airline. Both of those losses were really bad luck that could have, and have, happened to any airline.
Not just saying that, I've flown with them twice over the last year and another booked in a few months. After SingAir and maybe Thai, I think they're among the best in the region.
LionAir and AirAsia, on the other hand, I wouldn't get on even if their tickets were free...
