Why are eastbound flights faster than westbound flights?
As you suspected, it is because of the winds, specifically the [jet stream](_URL_0_), which mostly flows from west to east. The rotation of the earth makes no difference, because the atmosphere in which aircraft fly rotates with the earth. If the rotation of the earth did make a difference, logic…
The Short Answer
As you suspected, it is because of the winds, specifically the [jet stream](_URL_0_), which mostly flows from west to east. The rotation of the earth makes no difference, because the atmosphere in which aircraft fly rotates with the earth. If the rotation of the earth did make a difference, logically you'd expect the opposite effect – as the surface of the earth moves to the east, the aircraft, you might think, would move to the west relative to the earth's surface. But this isn't what happens at all.
