What the aircraft actually flies over
From Istanbul the path crosses Turkey, then Azerbaijan, then 413 km of open water, then Turkmenistan, then Iran, then Turkmenistan, then Afghanistan, then Pakistan, then India, then 545 km of open water, then Myanmar, then Thailand.
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 7,640 km. That is 127 km further, about 2% more, and roughly 9m of extra flying.
Leaving Istanbul the aircraft points east (91°); it arrives into Bangkok heading south-east (129°). That is 38° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.
