Miles City Airport - Frank Wiley Field — Miles City, United States

Miles City Airport - Frank Wiley Field (MLS) serves Miles City, Montana, a small city in the eastern plains of the state along the Yellowstone River. The airport provides essential regional air service through subsidized Essential Air Service flights connecting Miles City to larger hub airports, since the town's remote location makes highway travel to major cities time-consuming. Named for Frank Wiley, a local aviation figure, the airfield also supports general aviation, agricultural spraying operations, and occasional military training given Montana's vast open airspace. MLS is emblematic of the many small municipal airports across the northern Great Plains that rely on federal support programs to maintain scheduled commercial connectivity for isolated rural communities.
