What the aircraft actually flies over
From Istanbul the path crosses Turkey, then Iran, then Afghanistan, then Pakistan, then India, then 2,387 km of open water, then Malaysia.
The furthest the great circle gets from the equator is 41.3°N, 0% of the way along.
Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 8,790 km. That is 109 km further, about 1% more, and roughly 8m of extra flying.
Leaving Istanbul the aircraft points east (99°); it arrives into Singapore heading south-east (132°). That is 33° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.
