An online travel agent (OTA) helps client book flights, hotels, and vacation packages. Your duties vary depending on the type of travel products that you sell. Some virtual travel agents focus on pre-planned packages, while others create custom itineraries for their customers. You communicate with clients via email, chat, or telephone to assess their needs and then offer options to meet their travel requests. In addition to hotels and flights, you can also book car rentals, cruises, guided excursions, and spa treatments. You may use specialized reservation engines or book directly with airlines and hotels.
