Fuel load
@Alchad
Earlier Bloomberg article quote:
"The Boeing 777 was carrying 49.1 metric tons (54.1 tons) of fuel when it departed Kuala Lumpur, for a total takeoff weight of 223.5 tons, according to Subang Jaya-based Malaysian Air."
Whether that is "normal" for the planned flight path I leave to the pilots who know these machines.....
