A narrated demonstration of Cathay Flex, Henry’s team project for the Cathay Pacific Hackathon. Travellers earn credits by accepting suitable travel changes and use those credits across services and future journeys. The video shows how AI, constrained optimisation and a transaction and settlement system coordinate these arrangements.

A traveller describes which changes suit a short solo flight, a longer journey or a family trip. When another passenger needs the traveller’s aisle seat, Flex finds a compatible change. The traveller accepts and earns credits that remain available for a later journey.

On a subsequent family trip, the traveller asks for seats together and an extra bag. Flex presents one arrangement and a clear credit price, coordinating the passengers and resources needed. The demonstration also shows spending credits on Wi-Fi.

AI interprets passenger conditions. Constrained optimisation finds arrangements that work across the people involved. The transaction system coordinates confirmations, booking updates and credit settlement. Passenger flexibility gives the airline more ways to meet demand using its existing resources.
