Is it apparent that the person is peering out of a airplane window?

You can't "peer out the plane"; when you peer out (X), then (X) is the object through which you are peering. Unless the entire plane is made of glass or other transparent material, it is not a suitable object for being peered out.
You can, however, peer out OF the plane; in this case, "the plane" is the location from which you are doing your peering, and the ability to see beyond its confines is assumed.
I'd recommend "peered out the plane window" or perhaps "peered out through the plane's window".
I agree that "Mary relaxed her body as she peered out the plane" sounds a little awkward. Is she flying the plane? Is she ready to jump out? I would vote to say "peered out the window" and establish somewhere else that she is a passenger on the plane.
