Or do you say you are at rest because the passenger next to you is moving with you? You are having a hard time understanding reference frames. You are at rest with respect to the plane. You are at rest with respect to the passenger beside you (assuming they're sitting still, relative to the plane). You are not at rest with respect to the ground below. The whole point of relativity is that no inertial frame is in an absolute state of "motion" or "rest". The laws of physics are the same in all inertial frames, whether it be your plane or the earth itself.
