Implementation Reference

  • The `create_booking_url` helper function constructs a Google Flights URL using flight search parameters (origin, destination, dates, passengers, cabin class). This is the core logic for generating shareable Google Flights links, used as fallback when SerpAPI is unavailable.
    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. Args: origin: Origin airport code destination: Destination airport code outbound_date: Departure date return_date: Return date (optional) seat_type: Cabin class adults: Number of passengers Returns: Google Flights URL """ base_url = "https://www.google.com/travel/flights" # Build query params params = [] # Add origin and destination params.append(f"f=0.{origin}.{destination}.{outbound_date}") if return_date: params.append(f"*{destination}.{origin}.{return_date}") # Add passengers params.append(f"1.{adults}.0.0.0") # Add class class_map = {"economy": "y", "premium_economy": "w", "business": "c", "first": "f"} class_code = class_map.get(seat_type.lower(), "y") params.append(class_code) query = ".".join(params) return f"{base_url}?tfs={query}"
