Everything on the ground, in the water, or in the air also rotates - with the Earth - at the same speed as the Earth. What can impact the travel time for east-west vs. west-east are the prevalent. Our atmosphere is a mixture of gases that surround Earth. It is kept in place by the pull of Earth's gravity. If Earth was a much smaller planet, like Mercury or Pluto, its gravity would be to weak to hold a large atmosphere. Now back to the Earth. First, the Earth doesn't have an outer "bucket" edge to create viscous drag and cause a rotational flow. Secondly, the Earth has been spinning for awhile. Long enough that the viscous effects have made the atmosphere "drag along" with the body all the way through to the outer edge.
