Bain & Company has warned European hotel, resort, cruise and theme-park operators that AI platform referrals to hotel and short-term rental websites have quadrupled year-over-year, with other travel categories seeing AI's share of web traffic more than double. The data, drawn from Similarweb, anchors the consultancy's strategic alert on agentic commerce.

What does the traffic shift mean?

The fourfold rise remains from a low base. It nonetheless accelerates as Google rolls out travel booking functionality in AI Mode and as ChatGPT referrals to travel sites climb. Bain's Consumer Lab data shows 49% of US consumers who have used AI to research and book travel now rely on it "most of or all the time" for related tasks. The equivalent average across the UK, France and Germany sits at 41%.

What threatens direct bookings?

Two pressure points dominate. First, growing AI reliance could shrink direct bookings, pushing operators onto lower-margin indirect channels. Second, bots that prioritise cost during autonomous narrowing risk commoditising inventory. Smaller brands will be hardest hit by price-led matching. Bain analysts write that "smaller brands are more likely to be optimising for an agentic AI future than defining it."

The post-Covid growth slowdown complicates the response. Even operators defending their direct flow may face thinner economics if AI platforms absorb the indirect channel, gaining the negotiating leverage Google exercises today in search.

Could operators simply wait?

Online bookings reached an estimated 70% of the total in 2025, up from 43% in 2011. The split between direct and intermediary bookings, however, "remained broadly stable" across those 15 years despite mobile and social commerce disruption. Bain argues that the superficial stability masks consumer migration toward online travel agencies, with operators investing heavily in CRM to preserve the direct channel.

In a more challenging scenario, AI tilts the mix toward indirect bookings, limiting access to first-party data that powers personalisation and diluting margins. Bain cites AI's potential mastery of the inspiration stage as a catalyst that could move consumers toward AI platforms and AI-powered OTA tools over brand.com search.

What should operators do now?

Bain outlines three near-term priorities:

• Restructure online content for AI discoverability rather than traditional SEO, ensuring presence for historic and target use cases.
• Move marketing spend gradually toward AI platforms and build new capabilities as the mix shifts.
• Make direct booking at least as attractive as going through an intermediary, using AI personalisation, stronger loyalty offers and customer-facing AI tools that replicate AI-platform convenience.

The largest operators may wall off inventory from AI search partners or pursue joint ventures that protect margin from AI-powered indirect bookings. All operators should test AI-driven personalisation on property to deepen guest memory of the brand before the next AI-led search begins.

When does the next step arrive?

Industry data already records the traffic shift. Bain expects the next phase to be defined by agentic commerce launches from Google, OpenAI and other large platform players, alongside OTAs rolling out AI-powered trip-planning tools. Hotel groups that move on content, pricing and direct-channel AI investment before agentic booking reaches scale retain the strongest negotiating position.

European operators should expect revenue management teams to revisit pricing-transparency assumptions within 12 months, given the price-comparison muscle AI agents already bring to leisure travellers.
