Regardless of who or what the passenger in question is or was or maybe, he has bought and paid for a ticket on this service provided by United.. In this day and age it is unbelievable that airlines are still 'overbooking', we all have to pay for our tickets before we are allowed to board and I can't believe the old system of 'reservation' still exists. As for shifting crews.. then that is down to ops knowing in advance from crewing.. we are talking 4 crew members, maybe 2 flight deck and 2 cabin.. so definitely not a sickness move,, tech maybe.. But at the end of the day United.. and Chicago Police shuld be so ashamed of tthemselves... I do hope he finds a good lawyer.. I hope to hell I never have the opportunity or reason to fly with them.. Bring back Peoples Express !!!
