The Northwest Missouri Regional Airport is located just west of town on Highway 46.  The 175-acre site is maintained by a Fixed Base Operator (FBO).  The FBO manages the day to day operation of the airport to include sales of fuel, aircraft maintenance and flight training.  The City of Maryville and the Airport Board oversee the leasing of hangers and the strategic/long-range planning and budgeting for the airport.  Current projects include a revised Airport Master Plan, runway lighting upgrades and remodeling the pilots lounge.
