Price is a key factor influencing traveler’s path to driving a choice leading to a purchase. In a world of infinite paths to purchase, travelers make multiple searches and find the ‘best trip’ and ‘best deal’. The Offers Domain team is tasked with giving the customer a simple, clear, accurate, transparent pricing throughout their shopping and booking journeys. We do this by putting the customer first, creating capabilities that can be shared and presented to the customer that meet the travelers’ expectations in locally relevant ways and adhere to regulatory norms.
