We Tested 5 AI Models on Expiring Travel Inventory — Here's How They Failed

Last week, a conversation started in UCP Discussion between contributors from Google, a global travel IT leader, Zolofy, and our team. The topic: UCP can't handle perishable inventory. Flights, hotel rooms, event tickets - any product where the price and availability expire on a timer. The protocol has no standard way for ants to say “this offer is only valid for 15 minutes.” So we built the primitive and tested it. Here's what happened. The problem UCP works well for retail. A pair of shoes doesn't expire while you're deciding. But travel inventory does.
