On board service

Dear fellow airliner,

i have question regarding on board service.

Is anyone can help me to answer these?

I already put the highest on board on business and first class but it seems that the rating in first class is not to maximum.

It isn't possible to get it above 3 bars on short-haul flights.  On anything over 800km you can get it higher.

i am doing these for long haul flight

It is what it is, you cannot get better than that at 11500 km.
