We were flying Bozeman to Oshkosh and got detoured due to weather. O'Neill is as good as it gets regarding a small, well-maintained, inexpensive, and friendly FBO. It is surrounded by beautiful farmland, and the runways and taxiways are in excellent condition. The FBO was very comfortable; we even considered sleeping there overnight since there were two beds available.

Visited KONL several times now, and it remains a key consideration when planning our routes. A truly pleasant, tranquil facility. While I haven't utilized the courtesy vehicles, they appear well-maintained and readily accessible. The pilot lounge and sleeping quarters are quite comfortable.

All self-service pumps for Jet A premix and 100LL are available with a credit card machine located inside the lobby vestibule. The pilot lounge, restrooms, and lobby area are quite comfortable. They also provide ample crew cars.

Excellent stop! I was rerouted due to weather and required a fast fuel stop, and this location was extremely simple for arrival and departure. The lounge and restrooms were also very nice. Furthermore, Don assisted me with fueling my aircraft.
