Useful signals, with clear limits.
In the final prototype evaluation, five people attempted eight web and ten mobile tasks each. The project record reports 85 completed, three partial and two failed attempts across 90 participant-task attempts. Two people struggled with the route from Trip Plan to booking; some wanted more detail in itinerary cards.
There was no live booking business behind the prototype. Accessibility, translation and transactional infrastructure need further work before any real-world claim about adoption or trust.
