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.
"He tried to check in for a Chicago-to-Montana flight using an invalid ticket marked for a New York departure, Chicago police said.
El Ela raised his voice and became unruly after an employee at a Delta ticket counter refused to let him exchange the ticket for a valid one." (SunTimes)
