### Explanation
This Python script is designed to manage airline routes and calculate travel distances based on an itinerary.
- **Function `summary(routesMap)`**: This function prints out each possible route from an airport, showing the destination and the mileage to that destination.
- **Function `distanceUsing(routesMap, itinerary)`**: This is a placeholder function meant to calculate the total distance of the journey specified by the `it](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1f508c53-af29-498e-8791-77e45ebbdaaf%2Fa9a539e7-52f7-4e83-839f-0ae2835b47de%2Fdipg31p_processed.png&w=3840&q=75)
