What the aircraft actually flies over
From London the path crosses Netherlands, then Germany, then Poland, then Ukraine, then Russia, then Kazakhstan, then Uzbekistan, then Turkmenistan, then Afghanistan, then Pakistan, then India.
The furthest the great circle gets from the equator is 52.1°N, 13% of the way along.
Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 6,979 km. That is 248 km further, about 4% more, and roughly 18m of extra flying.
Leaving London the aircraft points east (80°); it arrives into Delhi heading south-east (136°). That is 56° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.
