A tour operator is a company or an individual that creates and operates tours or travel packages. They work directly with suppliers such as airlines, hotels, and transportation companies to create tour packages that include transportation, accommodations, activities, and other services.

 They often specialize in specific destinations, themes, or types of travel, such as adventure travel or luxury travel. Tour operators usually sell their tours directly to the public or through travel agents.

On the other hand, a travel agent is a professional who helps travelers plan and book their trips. They work on behalf of their clients to find the best deals on transportation, accommodations, and other travel services. Travel agents typically offer a wide range of travel-related services, including flights, hotels, car rentals, travel insurance, and more. They may work independently or for a travel agency and may specialize in certain types of travel, such as business or leisure travel.

In summary, tour operators design and operate tours and travel packages, while travel agents help clients plan and book their trips. Both play important roles in the travel industry and can help travelers find the best deals and experiences for their trips.
