Airline Checkin Obsessive Compulsive. Someone who obsessively seeks to obtain the lowest Airline Checkin position possible on airlines using festival seating.

The hallmark of a true Airline Checkin Obsessive Compulsive is the desperate, and unsolicited, need to assist others in the pursuit of the lowest Flight Checkin position. Persons with advanced stages of ACOC have been known to orchestrate elaborate Web Checkin processes at their places of work. These situations often involve the redirection of personnel from their normal tasks, usually at company expense disproportionate to the benefit of those involved.
