Google has confirmed that its generative AI search product, AI Mode, will change how consumers book flights and hotels this year — the clearest signal yet that the search giant intends to move travel from a links-and-ads business into a conversational, AI-mediated transaction flow.

The shift matters commercially because Google sits at the top of the travel demand funnel. Any change to how its search results surface flights and accommodations directly affects where bookings land — and who collects the commission.

For online travel agencies and metasearch players such as Booking.com, Expedia, Kayak and Trivago, the stakes are distributional. These companies built their businesses on paid visibility within Google's travel results, through metasearch cost-per-click and cost-per-acquisition placements. If AI Mode answers a query like "flights to Tokyo in April" with a conversational recommendation and an in-flow booking path, the traditional listing inventory that intermediaries buy loses value.

Airlines and hotel chains face a different calculation. Direct booking has been the margin strategy for both groups for a decade. An AI Mode that pulls structured content from supplier systems could, in theory, strengthen direct channels — or could insert Google itself as a new layer between the brand and the customer, replicating at the AI layer what metasearch did to supplier economics in the 2010s.

The development also lands amid regulatory scrutiny. Google's travel products have drawn competition complaints in the EU and the US for years, and folding booking capability into an AI answer that the company itself controls will test how regulators treat generative search as a distribution channel. European regulators in particular have examined whether Google's vertical answers disadvantage comparison services; an AI booking layer sharpens that question.

For sellers of travel, the practical agenda is data readiness. AI Mode's answers will lean on structured feeds, pricing accuracy and content quality. Suppliers and intermediaries that keep clean, machine-readable availability and rate data will be better positioned to appear inside AI-generated answers than those relying on legacy integrations.

What remains unquantified is uptake. Google has not published projections for how many travel queries will route through AI Mode this year, and no booking volumes through the new interface exist yet. Every claim about the scale of the shift, for now, is a projection rather than a measured result.

The direction, however, is set: Google intends to host the travel booking conversation, not just the search that precedes it. Intermediaries and suppliers will spend 2025 watching — and negotiating — how that conversation pays out.
