search_travel_options
Primary travel search workflow for one origin-destination airport pair. Use when the user wants flight/trip options for a specific route; use compare_routes for multiple routes, build_booking_link only when route details are already known, and get_airport_info only to validate one airport. Read-only, no authentication, no booking side effects. return_date is optional; omit it for one-way trips. Responses include route metadata and may include commission-eligible external booking links.
