Booking’s Lola AI Assistant Adds Flight Booking, With $100 Million Investment Planned

The AI concierge that started with hotels can now book flights — and Booking Holdings is backing it with serious capital.

Lola, Booking Holdings’ AI travel assistant, is leveling up. The company announced that Lola will gain flight booking capabilities, transforming it from a hotel-only helper into a fuller-service AI travel planner. To accelerate the work, Booking Holdings is planning a $100 million investment in the assistant’s development.

Lola has been positioned as a test lab for how travelers actually want to interact with AI when planning trips — free-form conversation rather than filters and dropdowns. Adding flights is a significant step in usefulness, because multi-part trips are where AI assistance gets real: coordinating flights with hotel stays, surfacing alternatives when prices shift, and handling the back-and-forth adjustments that human travelers actually make.

For Booking Holdings — the parent of Booking.com, Priceline, Agoda, Kayak and OpenTable — the assistant strategy plays a dual role:

• Defending its massive direct-booking funnel as travelers experiment with AI chat assistants for trip planning
• Putting the company’s enormous inventory, supply contracts and pricing data behind an interface its own brand controls

Industry context matters here. Rival Airbnb has its own AI agent slated for a first-half 2027 debut, while startups in this year’s PhocusWire Hot 25 are building agentic booking infrastructure from scratch. And the wider conversation about AI assistants in travel has been shifting from chatbots that answer questions to agents that complete transactions.

Booking’s larger AI assistant performance data — reported separately — suggests its earlier experiments are producing measurable results rather than demos. With $100 million earmarked, the company is betting that in the next phase of travel AI, scale and supply depth beat conversational charisma.
