My friends often visit JFK's Terminal One to spot planes. Suddenly on Sat. July 24, they were told to leave by a lady. I don't know her position. She said if she ever saw them again, they would be arrested. Can spotters get banned from JFK? They weren't doing anything suspicious as far as I know, not even using cameras or binoculars. I also visit Terminal One to see the new Airbus A380. I am worried she will bother me, too. Is there any recourse if told to leave?
