Remember, the atmosphere is also rotating with the earth, with means the effect of the earth's rotation can be ignored. The air and any airplanes in it are rotating at the same rate as the surface of the earth. People try to make these problems a lot more complicated than they really are.

Ignoring winds, and assuming identical aircraft and weather conditions, travel time would be exactly the same regardless of direction. Clock time will change becasue you cross multiple time zones. In practice, in North America west to east flights are generally faster than east to west becasue the jet stream helps in one direction and hinders in the other.
