Since 28 September, Booking.com has stopped sending guest phone numbers to PMS and channel managers, and many independent hotels only noticed when their pre-arrival WhatsApp and check-in flows went quiet. Booking will cite fraud, and it has a point: TUI just admitted a breach in Belgium after travellers received scam messages quoting accurate booking details, following an earlier attack on Booking.com itself. Fine. The outcome for the hotel is the same. The guest relationship is the asset, and the platform just took a piece of it back.
Read the rest of the week through that lens. Booking Holdings reportedly plans to put $100 million into Vayo, an AI startup built to monitor the whole trip and learn how each traveller moves. That is the same relationship, rebuilt as software the OTA owns. The Verge reports websites blocking autonomous agents just as those agents start booking, while Google is moving inline links higher in AI Overviews and AI Mode, which reopens some referral traffic for sites worth linking to. Access is being renegotiated offline too. The CJEU ruled in case C-857/24 that airlines can lose historic slots where a binding cap limits capacity, as at Dublin, a precedent Routes World delegates in Frankfurt should discuss this week. Capital follows secure access: Cushman & Wakefield says one in four euros invested in European hotels now goes to Spain.
My read for the next year: more data restrictions justified by security. The ETC's Long-Haul Travel Barometer finds 70% of potential long-haul travellers want to visit Europe, often on multi-country itineraries, exactly the trips an agent like Vayo will try to orchestrate end to end. DMOs that haven't set terms for agent access to inventory will have those terms set for them. Hotels should capture phone numbers at check-in and in their own booking engine now, and tell guests they never request payment by message.
One paper is worth watching: it found OpenAI's API only partly matches ChatGPT's citations, so your GEO dashboard may be wrong. Also worth watching is eHotelier's case that AI search is now a standard step in hotel discovery. Mindtrip's always-on personal agent deserves attention too, though it remains a vendor claim, not adoption data.
So here is the question for every independent: if Booking disappeared tomorrow, how many of last month's guests could you actually reach?
Key questions this week
Why did Booking.com stop sending guest phone numbers to hotels?
Since 28 September, Booking.com no longer passes guest phone numbers to property management systems and channel managers, and it cites fraud as the reason. The change follows scam messages that quoted accurate booking details, including an earlier attack on Booking.com and a breach TUI admitted in Belgium. For independent hotels, it has cut off pre-arrival WhatsApp and check-in flows that depended on those numbers.
How can hotels get guest phone numbers if Booking.com no longer shares them?
Hotels can collect phone numbers directly at check-in and through their own booking engine. They should also tell guests they never request payment by message, which helps protect against scams that use real booking details. Direct contact data keeps the guest relationship with the hotel rather than the platform.
How should DMOs prepare for AI agents booking travel inventory?
DMOs that haven't set terms for how autonomous agents access their inventory are likely to have those terms set for them. Booking Holdings reportedly plans to put $100 million into Vayo, an AI startup built to monitor the whole trip, while some websites are already blocking agents just as they start booking. These agents target multi-country trips, and the ETC's Long-Haul Travel Barometer finds 70% of potential long-haul travellers want to visit Europe, often on itineraries that span several countries.
