Galileo is a global distribution system (GDS) software primarily used in the travel and tourism industry. Developed by Travelport, Galileo enables travel agencies, airlines, and other service providers to access real-time information about flight bookings, hotel reservations, car rentals, and other travel-related services. 

It serves as an intermediary platform that connects suppliers with travel agents and businesses, allowing them to search, book, and manage travel services across a wide network. The system is widely used by both large agencies and smaller travel businesses to streamline their operations and improve efficiency in managing bookings and customer service.

The cost of Galileo software in India depends on various factors, such as the type of service, the scale of the business, and the specific needs of the user. For large travel agencies, airlines, and other high-volume travel providers, the pricing is often based on the number of transactions processed or the volume of bookings made. Larger businesses may negotiate custom pricing with Travelport, which could involve monthly or annual licensing fees. 

For smaller travel agents in India, Galileo typically offers more affordable, scaled-down solutions with a lower volume of transactions or fewer features. The cost for these smaller-scale packages can vary, but generally, users may expect to pay a subscription fee, which might range from a few hundred to a few thousand dollars per month. Businesses looking to use Galileo's services should contact Travelport directly for a tailored quote based on their specific requirements and usage patterns.
