Online Travel Agencies (OTAs) are websites that help travelers book various travel services, such as flights, hotels, and car rentals, all in one place. They provide a user-friendly platform where you can compare prices, read reviews, and find deals from different providers. Popular OTAs include Expedia, Booking.com, and Kayak, making it easier for people to plan their trips without visiting multiple sites. These agencies often offer special discounts and packages, making travel more affordable. By using an OTA, you can save time and effort while ensuring you get the best options for your travel needs. They also provide customer support to assist with any issues that may arise during your journey.
