What the aircraft actually flies over
From London the path crosses United Kingdom, then Netherlands, then Germany, then Poland, then Belarus, then Ukraine, then Russia, then Kazakhstan, then Uzbekistan, then Afghanistan, then Pakistan, then India, then 1,823 km of open water, then Malaysia.
The furthest the great circle gets from the equator is 52.5°N, 10% of the way along.
Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 11,349 km. That is 466 km further, about 4% more, and roughly 35m of extra flying.
Leaving London the aircraft points east (78°); it arrives into Singapore heading south-east (142°). That is 65° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.
