AI Flight Search & Comparison with DeepSeek and Google Flights

This n8n workflow powers an intelligent travel assistant that interacts with users via chat to gather departure/destination cities, IATA codes, and travel dates. Leveraging a Langchain AI Agent connected to DeepSeek Chat Model for reasoning, Simple Memory for context, and SerpAPI's Google Flights tool for real-time data, it searches multiple airlines, compares prices, durations, and stops, then suggests flexible dates for savings.

Key benefits include automation of tedious flight hunting, real-time price tracking with alerts, and personalized 24/7 AI advice, saving users hours and money on trips. Ideal for travel agencies, booking sites, or personal use, it handles complex queries like multi-city itineraries or budget optimizations.

Setup is straightforward for self-hosted n8n: add DeepSeek and SerpAPI credentials, configure AI Agent links, set SerpAPI engine to 'google_flights', and test via chat input. Community nodes ensure advanced AI capabilities, making it scalable for high-volume travel automation.
