Classify the primary travel intent (flight_search, hotel_search, activity_search, full_package, itinerary_query, price_alert, booking_modification, general_question)\n2. Extract all travel entities: destinations, dates, passenger count, budget, preferences\n3. Identify date flexibility (exact dates vs. flexible)\n4. Detect urgency level from tone and phrasing\n5.
