Booking.com Parent Company Reveals Real AI Savings in Customer Service
Booking Holdings, the parent company behind Booking.com, Agoda, Priceline, and Kayak, reported a concrete result that most companies are still chasing: its customer service costs fell in absolute terms last year, even as gross bookings grew by roughly 10%. The data came out of the company’s Q4 2025 earnings call, where CFO Ewout Steenbergen pointed to the figure as proof that generative AI is delivering real financial returns.
The savings show up in the company’s sales and other expenses line. AI-driven customer service efficiencies brought costs down enough to offset rising payment volumes, resulting in net savings for the full year.
“GenAI is everywhere except for in the P&L,” Steenbergen said, citing a remark from a peer CFO. Booking Holdings, he argued, can point to a specific line in its financials where AI is making a measurable difference.
Costs Down, Bookings Up
The result lands at a moment when the industry is still struggling to move from AI deployment to AI payoff. Gartner research shows that over half of customers say they would be happy to let a GenAI assistant handle support on their behalf. And while service leaders are under growing pressure to automate, translating that into bottom-line results has proven difficult for most organisations.
Booking Holdings appears to have done it, at least in one area. The company confirmed that generative AI now handles a significant number of customer service interactions across its brands, reducing the volume of cases that require human agents without compromising service quality.
In 2026, Booking Holdings is targeting between $500 million and $550 million in in-year savings through its transformation programme, with customer service AI contributing to that figure alongside wider operational efficiencies. A portion of those savings will fund further GenAI development across the traveller journey. The group has been deploying AI across its business for years, but customer service is where it has produced the first hard numbers.
