Both major Malaysian airlines flight accidents were using 777's
Indeed, but those were also both 777-200ER's iirc
I stated
There has literally been no major incidents involving a Boeing 777-300 series plane, and only few with the 200 series.
with emphasis on the -300 part in case someone would immediately say that
find a list of all boeing 777-300 series aircraft, and you'll see not one has ever been lost yet, which is pretty damn good
