The journey from Malaysian Airways to Malaysian Airlines System has indeed helped the airlines. Also known as MH for its airline code, it is indeed one of the best airlines in the region. The destinations offered are impressive and with code sharing flights you get more destinations.
All long distance flights have LCD TV on every seats in the economy class. The service is excellent. And of course you get authentic Malay food (if flying in that sector). Friendly and pleasing air hostess will make you feel comfortable throughout the journey. Its fares are one of the lowest in the region.
I have done some 30 odd hours of flying on MH, on SIN-KL-AKL-KL-SIN sector, and recommend it to be one of the best airlines in the region.
