Former Spanish Prime Minister Aznar and his son were sitting one row in front of me on a JFK-MAD flight. His two security detail were seated in the middle row parallel to me. A Porshe SUV picked them up when we landed and whisked them away. President Carter was on my flight from Birmingham to ATL. He boarded the plane last and then proceeded to shake everyone's hand on the plane with secret service in front and behind him. As soon as we landed, all passengers were instructed to remain seated until the President departed the plane (two black suburbans were waiting for him at the bottom of the jet bridge stairs).
