Implementation Reference

  • Helper function that constructs a Google Flights URL (tfs parameter format) from flight parameters. This is the exact implementation for generating the Google Flights shareable link used in the fallback flight search.
    def create_booking_url(origin: str, destination: str, outbound_date: str, return_date: Optional[str] = None, seat_type: str = "economy", adults: int = 1) -> str: """ Create Google Flights booking URL.
