How does the rotation of the earth affect air travel?

When you take a flight, one can imagine how you can either fly along with the rotation of the earth or against it. 

Yet a quick google search shows, a flight from New York to Tokyo is about the same time as a flight from Tokyo to New York. 

Why is this, and how exactly does the rotation of the earth affect our air travel?

it has an effect due to the winds, and those winds blow the way they do largely due to the rotation of the earth (and how the sun heats up a portion of the earth as it (the earth) rotates under it).

It is quite a significant effect at mid latitudes.  For instance,  a flight going east is probably 25% or so quicker (and less expensive) than the same flight going west.
