Chicago Mainliner Club

The Chicago Mainliner Club is part of United Airlines and is a non-for-profit employee social club. We facilitate discounts for various events around the Chicago area, organize employee functions and sell United Airlines merchandise with the intention of promoting employee morale and Unity. We are United Mainliner, and we proudly welcome Continental Airlines to our Club. In addition, employees of Alliant Credit Union are also considered members of the Chicago Mainliner Club and are eligible to participate in all events, activities, and discounts.
