The Helicopter Service area is around 150 miles around each base. In 2014, Arch relabeled all of its bases and now the call sign doesn't change regardless of the aircraft in use.
In 2013, Arch closed its fixed wing program due to low volumes and the parent company, Air Methods, providing this service through their newly acquired company American Jets.
In 2012, Air Methods opened its central dispatching center in Omaha, Nebraska and Arch dispatch was removed from service.
Also included in the Arch region are the following community-based services.
The following hospital-based services are sister programs of Arch and are owned and operated by Air Methods.
