One was arrested at Chicago's O'Hare trying to use his ticket from NY to MT. He got irate at the ticket counter and that's what flagged the local Chicago police officer to take him aside for questioning.
Was he trying to get to Montana from Chicago or was he trying to cash in the ticket to another destination? I wonder what caused him to be irate.
I fly frequently, I get from point A to point B 10 to 15 times a year, year after year, and never have had a situation where I needed to become irate.
