## How we test this category

An agent searches a return flight and a hotel, holds or books where the sandbox allows, then changes and cancels. We check the inventory, the booking and payment steps, the change flow and what getting access took. This test hasn't run yet, so Task success is pending and the grades here come from the categories assessed from public evidence.
