Yes, CO has a "remote agent" system set up. They did this when they closed some call centers. A lower pay scale than regular reservations. but they do have this option. it is a point of contention in the merger, as there currently is a vote going on to determine if the combined UA/CO res and CS will be represented by a union or not. UA's union argues they should be paid the same as the brick and mortar as the cost to the airline is less (lower overhead to the company) while the airline argues they should be paid less due to the lower cost to the employee (lunches at home, not commute.)

This differs from UA's "remote agent" set up, which is located in Asia, is not from home and labor costs are far less with agents not being employed directly by UA/CO (ie the India ICC.)
