The prevailing winds add to the aircraft's ground speed in one direction and reduce it the other direction. In the northern hemisphere the prevailing winds are from the west, so flying to the east takes less time as the plane has a "tail wind". Going west there is a "head wind". The aircraft's airspeed is the same going both directions, but the extra wind effects the ground speed.
Example: Tail wind of 50 mph, airspeed of 500 mph, ground speed of 550 mph. Head wind of 50 mph, airspeed of 500 mph, ground speed of 450 mph. This is an over-simplification, but that's the basics.

Whether your are flying into or against the wind can make a big difference. Also, even though you are theoretically traveling between the same two points, the air traffic routes may vary slightly.
Off topic, but what I've never understood is Air France's Paris - SFO schedule. They have two flights arriving at SFO from Paris daily, but only one leaving...

The Jet Stream. One way you're going with the wind. The other you're going against the wind. (Hey, that'd be a good tile for a song. Any Bob Seger fans?)

You went into a different time zone? Or you had more road construction and traffic going one than the other.

1. Head winds
2. Tail winds
3. cross winds
4. altitude- lower is farther distance to travel and higher is shorter.

a longer lunch break on one way, or on a plane it's a long layover, or a stop at the airport for lunch or time in the gift shop to look at things.
Any of those work?
