Is it true that it takes longer to fly west than any other direction?

Yes, it’s mostly true.  While the shortest distance between two locations is a straight line, which means you will almost always blow right past the same point on the globe to reach a far destination on the east or west, it takes more miles to get where you’re going.  The major factor here is that the earth is not flat, but rather an elliptical sphere, so the distance lengthens as you move toward the equator.  While there are some shorter overland routes, distance from pole to pole is the longest, by far.

Whaaaat?  Are you sure this is a true statement?  I think this bears no correlation to reality!  It’s certainly true that flying west takes longer than flying east, but it hasn’t ever been my experience that “it takes longer to fly west than any other direction”.  If you travel far enough, then I think you realize that there is no difference in flight distance, considering that you go around the entire globe.  Based on the earth’s curvature, it is true that directions in a plane are offset relative to arcs around the globe.  But I think this is just an extremely misleading idea, popularized by a widely-circulated online false fact.  This idea makes no sense in the real world, and I don’t recommend putting any stock in it.  But if it makes you feel better, there’s nothing preventing you from flying in a circle around the globe to eventually arrive in exactly the place you started -- but it will make for a very, very long trip, and you probably won’t want to do this IRL.
