The Wisconsin Coach Lines app is the only official app for tracking your next trip on our Coach USA Airport Express service or our commuter services in southeastern Wisconsin. Enter the details of your trip to find your departure and arrival times. Directions are provided for each stop serviced to ensure you're at the correct location awaiting your bus. The app can save multiple trips scheduled for today. This app presently supports Coach USA Airport Express service between Waukesha, Milwaukee, Racine, Kenosha and Chicago's O'Hare Airport. Waukesha County Express commuter service between Waukesha and Milwaukee Counties and our daily Kenosha/Racine/Milwaukee inter-city commuter service will be added in the future.
