Animate 3d model on top of another model

Hello, Is there any way to move 3D model on top of another model?
I have 3D model for an airport and I have some models for airplanes. Is it possible in three.js to move the airplane on a specific path at the airport?

Check out how a camera is animated along a spline curve in the following example (enable the camera helper to see it):

You might want to use a similar approach for animating your object. You only have to define the path as an instance of THREE.Path.
