W. K. Kellogg Airport[1][2] (IATA: BTL, ICAO: KBTL, FAA LID: BTL) is a city-owned, public-use, joint civil-military airport located three nautical miles (6 km) west of the central business district of Battle Creek, a city in Calhoun County, Michigan, United States.

The Battle Creek Field of Flight Air Show and Balloon Festival is also held annually at Kellogg Airport.

[8] In September 1924, the Battle Creek Chamber of Commerce signed a five-year lease of a farm, with the option to purchase, for an aviation field.

The company built a new facility to include a reception area for transiting pilots, larger space for mechanics, and a restaurant opened to the public.

[13] That same year, Western Michigan University's College of Aviation announced plans for a new instructional facility at the airport to include classroom space, a computer room, composites/paint laboratory upgrades, a new flight simulation center, a research center, briefing rooms, office space, a café, and more.

[1][15] The airport has two fixed-base operators offering fuel as well as general maintenance, catering, courtesy transportation, conference rooms, a crew lounge, and more.

[16] For the 12-month period ending October 31, 2021, the airport had 96,000 aircraft operations, an average of 263 per day: 68% general aviation, 31% air taxi, 1% military, and <1% commercial.
