Two weeks ago I wrote about why AI travel agents can dream up the perfect trip but can’t book it.
Less than two weeks later, Google launched the Universal Commerce Protocol with Shopify, Walmart, Target, and 20+ retail and payments partners.
Timing.
My take (probably the nth in your feed): UCP is different from what came before. Open contributor model, vertical expansion explicit in the roadmap, Google and Shopify co-building the specs. Travel is listed as “upcoming” alongside Services.
The problem: v1 is retail. Shopping carts, shipping addresses, return policies. Travel doesn’t work like that.
When an agent books a multi-city trip with flights, hotels, and a rental car, who’s the merchant of record? What happens when the flight changes and the hotel needs cancelling? Where do Package Travel Directive obligations live in a protocol designed for sneakers?
These aren’t edge cases. They’re the entire vertical.
The window to shape these specs is now, while the architecture is still wet. Travel companies that show up to the GitHub with real requirements will define how agents book. Everyone else will adapt to whatever emerges.
I’ll be contributing. Article explains what travel needs to bring to the table.
