Trigger & Extract: Receives destination, dates, preferences, extracts parameters.\n2. Data Gathering: Parallel APIs fetch flights, hotels, activities, weather, merges responses.\n3. AI Processing: Analyzes data, creates itinerary, ranks recommendations.\n4. Delivery: Generates HTML email, sends via Gmail/Slack, confirms completion.\n\n## Setup Instructions\n1. API Configuration: Add keys for Skyscanner, Booking.com, Kiwi, Viator, OpenWeatherMap, OpenRouter.\n2. Communication: Connect Gmail OAuth2, Slack webhook.\n3. Customization: Adjust endpoints, AI prompts, HTML template, scoring criteria.\n\n## Prerequisites\n- API keys: Skyscanner, Booking.com, Kiwi, Viator, OpenWeatherMap, OpenRouter\n- Gmail account\n- Slack workspace\n- n8n instance\n\n## Use Cases\n- Corporate travel planning\n- Vacation itinerary generation\n- Group trip coordination\n\n## Customization\n- Add sources (Airbnb, TripAdvisor)\n- Filter by budget preferences\n- Add PDF generation\n- Customize Slack format\n\n## Benefits\n- Saves 3-5 hours per trip\n- Real-time pricing aggregation\n- AI-powered personalization\n- Automated multi-channel delivery", "workflow": { "id": "Yi6ZHj09hQ6aoCt2", "meta": { "instanceId": "b91e510ebae4127f953fd2f5f8d40d58ca1e71c746d4500c12ae86aad04c1502", "templateCredsSetupCompleted": true }, "name": "Qwen3-VL-8B-Thinking Travel Planner: Search-->Compare-->Email Best Itineraries", "tags": [], "nodes": [ { "id": "f3a23f51-4039-4a08-bad5-d9e1f475e8af", "name": "Webhook -
