It tells the AI how to **extract structured airline web check-in data** (like check-in time, baggage policy, cancellation rules) from messy airline webpages.\n\n#### 🎯 Why is it used?\n\nAirline websites often present data in unstructured formats. This LLM-based step:\n\n* Cleans the content scraped from airline URLs.\n* Extracts important travel-related info in a consistent JSON format.\n* Helps automate the enrichment of airline data stored in your Google Sheets and Vector DB.\n\n#### 🛠️ How to use it?\n\n1. **Input**: This node receives raw webpage content from the airline’s \"Web Check-in URL\".\n2. **Prompt**: It applies a fixed set of rules (in natural language) to guide the AI to convert the unstructured data into clean JSON.\n3. **Output**: The AI returns a **structured JSON** object with fields like:\n\n   * `checkin_url`\n   * `baggage_allowance`\n   * `refund_policy`\n   * `faq`\n   * `additional_info`\n4. The next nodes save this output to:\n\n   * Google Sheet (for visibility)\n   * PGVector (for semantic search)\n\n💡 **Pro Tip:** This works best when the HTML content is readable and includes useful labels like “Check-in”, “Cancellation”, “Support”, etc.\n\n\n"
