Mirai has deployed the first ChatGPT plugins that let guests complete hotel reservations inside the assistant, with four Spanish brands live at launch: Emperador and Moderno in Madrid, Porcel Hoteles in Granada, and Gloria Thalasso & Hotels in the Canary Islands.

The integration exposes the booking engine's transactional layer—availability, pricing, currencies, promotions, booking, modification and cancellation—rather than reproducing the hotel website inside ChatGPT. Users can ask in natural language for a specific date, occupancy, rate type and ancillary requests such as breakfast or a cancellable policy; the plugin handles the rest without redirecting to the brand's site.

What separates Mirai's plugin from earlier attempts?

Existing hotel integrations on ChatGPT typically mirror a visual interface inside the assistant and bounce the user to the website the moment a transaction begins. Mirai's plugin keeps the booking inside the conversation by routing requests through the brand's own direct channel and the company's Model Context Protocol (MCP) layer—the same backbone powering Sarai, Mirai's conversational booking engine and the rest of its conversational channels.

Who pays, and what replaces what?

The deployment replaces a click-to-website flow with a voice-or-text conversational flow. For operators, the question is whether running direct reservations through a third-party assistant changes the economics around channel fees, conversion attribution and brand-controlled merchandising. Mirai is not disclosing per-booking economics yet, but the architecture is designed so the plugin acts as a gateway while the direct channel's capabilities and pricing stay under the hotel's control.

What did the operator say?

Pablo Delgado, Mirai's Managing Partner & CEO America, framed the launch as a defensive move for the direct channel rather than a volume play. "The challenge for hotels is no longer just to be discoverable by AI, but to ensure that their direct channel is also operable by it," Delgado said. "OTAs are already preparing to compete in this new agent-driven ecosystem. The direct channel must do the same."

What does the rollout look like in this phase?

Mirai has positioned the rollout as experimental: deployments remain limited while the company gathers data on discovery mechanics, funnel placement and user behavior. The plugin ecosystem is still new—OpenAI recently renamed "Apps" to "plugins" as the current terminology—and Mirai is not projecting high booking volumes in the near term.

The company's stated next step is gradual expansion of the capability across its hotel portfolio, contingent on what the early phase reveals about how travelers find and interact with hotel plugins. The bigger unresolved question is whether plugins serve only lower-funnel conversion or extend into inspiration and recommendation phases, where OTAs and metasearch engines already compete. Being discoverable will let a hotel join the conversation; being operable will let it compete for the booking.
