AI Overviews
Google's generated answer shown above the traditional results on a search page.
AI Overviews put a synthesised answer, with a handful of links, between the query and the result list. For travel queries that are informational (what to see, when to go, how long to spend), the overview can satisfy the question entirely, which is the mechanism behind zero-click behaviour.
