For me being able to decide when to eat is important on a long flight. Should be called meal on call as not only can you pre order but you can chose within reason when to eat. As far as I am aware all this entails is the option to order before you fly and then the crew stick it in the microwave to heat just like the other meals
I do find that it is disappointing that there is not more ringing of the changes and more Malaysian options but I have found the food on long haul to be very tasty with MAS
