OCCC is a coalition of pilot unions of Oneworld Alliance.  There are 13 pilot unions and 28,000 members in the organization from around the world.

The objectives of the Coalition are:

• To establish an ongoing exchange of information;
• To share our knowledge and experience in the airline industry, including details of our collective bargaining agreements, national laws and regulations;
• To share other information important to protect and enhance our professional interests; and
• To avoid any action that could reduce the leverage available to another Member Association.
