An Online Travel Agency (OTA) is a digital platform that allows users to book travel-related services, such as flights, hotels, and car rentals, through the internet. OTAs provide a convenient way for travelers to compare prices, read reviews, and find deals from various providers all in one place. Popular examples of OTAs include Expedia, Booking.com, and Kayak. OTAs typically earn revenue through commissions from service providers or by charging service fees to customers. They often offer user-friendly interfaces and customer support to assist travelers in planning their trips. By using an OTA, travelers can save time and effort in organizing their travel arrangements.
