Why is it that my flight isnt any shorter when I'm travelling in the opposite direction to the Earths rotation?

Because the atmosphere is rotating with the earth, and as a plane gets it's propulsion from sucking air through their engines, the rotation has no effect.

However, thanks to strong winds at high altitudes, called jet streams, sometimes a flight can be considerably quicker in one direction than the other for some routes.
