ChatGPT, an AI-powered chatbot app, has gained 100 million users within two months of launching on the market. The app is now being utilised by travel businesses to create chatbots, digital assistants and self-serving help desks. Expedia and Kayak were among the first travel chains to embrace ChatGPT, allowing clients to search for flights and hotels within the app, while Expedia also launched a trip-planning feature that uses ChatGPT to create user-generated itineraries. Travel firms are now using ChatGPT to field consumer queries, offer 24/7 support, personalise recommendations, provide relevant information and enhance marketing strategies.
