What the aircraft actually flies over
From Rome the path crosses Italy, then Croatia, then Hungary, then Ukraine, then Belarus, then Russia, then China, then 816 km of open water, then Japan.
The furthest the great circle gets from the equator is 61.2°N, 46% of the way along.
Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 11,080 km. That is 1,188 km further, about 12% more, and roughly 1h 29m of extra flying.
Leaving Rome the aircraft points north-east (40°); it arrives into Tokyo heading south-east (144°). That is 104° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.
