Composed of 24 of the major cruise lines serving North America, Cruise Lines International Association (CLIA) is the world's largest cruise association, dedicated to the promotion and growth of the cruise industry. CLIA operates pursuant to an agreement filed with the Federal Maritime Commission under the Shipping Act of 1984, and serves as a non-governmental consultative organization to the International Maritime Organization, an agency of the United Nations.
CLIA was formed in 1975 in response to a need for an association to promote the special benefits of cruising. In 2006 CLIA merged with the International Council of Cruise Lines (ICCL), a sister entity created in 1990 to participate in the regulatory and policy development process of the cruise industry. CLIA exists to promote all measures that foster a safe, secure and healthy cruise ship environment, educate and train its travel agent members, and promote and explain the value, desirability and affordability of the cruise vacation experience.
