🏠 In a 2026 survey, 38 AI trip planning companies were examined. The largest category is "AI plans, you book." None of these companies owns hotel rooms or airline seats. Most competitors (23 planners) rely on fragmented public content, making them vulnerable to platforms with better access. The market has a high ratio of planners to bookers, indicating low-entry barriers. True market strength lies with those owning inventory or customer relationships, not the full 38 companies.
