# How to Search Multi-City Flights with Copilot

Copilot searches multi-city flights from your IDE, useful for planning conference circuits or multi-office visits. Search each segment and get total itinerary costs, check if regional carriers offer cheaper inter-city hops, and build structured travel plans without switching to booking websites.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Add ToolRouter to Copilot MCP config
2. In Copilot Chat: "Plan flights for a 3-city European trip from Boston: London, Berlin, Amsterdam"
3. Copilot searches each segment and returns pricing for the full itinerary
4. Ask: "What is the total cost and what airlines serve each leg?"

## Example Prompt

```
Search multi-city flights from Seattle: Seattle to Munich, Munich to Prague, Prague to Seattle. Two weeks in November.
```

## Tips

- Useful for planning conference circuits that hit multiple events across cities
- Ask Copilot to check if regional carriers offer cheaper inter-city segments
