Will flying in the opposite direction of the earth's rotation make you travel farther in less time?

It's just something I was wondering. If two airplanes are traveling at the same speed, one in the opposite direction of the earth's rotation, the other with the rotation of the earth, will the first airplane (against the rotation) get to a certain equidistant destination faster?

No. The plane's frame of reference is rotating at the same rate as the Earth and the atmosphere, so its ground speed doesn't change if it flies east or west. In order to achieve what you're describing, you need to have a frame of reference independant of the atmosphere's rotation (i.e. in space).
