Find the Best Flight Prices
Search across airlines and routes to find the cheapest flights for your travel dates and destination.
Compare Airline Routes and Connections
Analyze different routing options between cities including direct flights, connections, and alternative airports.
Quick answer: Use the Flight Search tool through ToolRouter to compare airline routes and connections directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolGetting from point A to point B by air often involves choices beyond just picking the cheapest ticket. A direct flight saves time but costs more. A connection through a hub might be cheaper but adds hours. Flying into an alternative airport could save money while adding a short ground transfer. Understanding all routing options helps you make a decision that balances cost, time, and convenience.
The search_flights skill returns options across different routing strategies, and find_airport helps identify alternative airports near your destination. You can compare a nonstop flight against a connection that saves $200 but adds 3 hours, or check if flying into a smaller regional airport makes sense. This holistic view of routing options is something no single airline website provides.

Get all routing options for your trip, then evaluate the time-versus-cost trade-offs, check alternative airports using find_airport, and identify which connections have the most comfortable layover times. The conversation produces a routing decision, not just a list of flights.
