   investigating
   We are currently investigating an issue affecting the Google Flights API where searches using the `deep_search` parameter may timeout. At this time, the issue appears to impact the majority of requests made with this parameter enabled. Public Roadmap: https://github.com/serpapi/public-roadmap/issues/2749 As a temporary workaround, we recommend omitting the `deep_search` parameter. We apologize for the inconvenience and appreciate your patience while we work on a fix.
