Is it obligatory to make up the day for someone who broke their fast on an airplane, thinking that the time for breaking the fast had begun, and then it became clear that the time had not yet begun due to the difference in timing in the air compared to on the ground?

The traveler on an airplane breaks their fast when the sun's disk sets for them on the plane, not according to the time of the country they departed from or the one they are heading to. Whoever breaks their fast before the actual sunset for them, their fast is invalid and they must make it up, even if their breaking of the fast was based on the time of another country or due to the belief that the sun had set.
