i have flown malaysian for over 4 years now ,i travel 4 times a year and have not had any complaint with the airline.granted i tend to fly businesss not economy but whenever i have flown economy have found the service to be great.
all airlines stop non profitable routes,of which i have been a victim of with the ewr legs,but malaysian airlines were happy to pay for hotels of my choice when things needed rescheduling.
i think that given they are one of the cheapest carriers from asia they do well.
