Frequently asked questions
What is the longest runway at KMLI?
Quad Cities International's longest runway is 09/27, a 10,002-foot concrete surface with a width of 150 feet. This length places KMLI among facilities capable of handling large business jets and cargo aircraft without runway-length restrictions. A second paved runway, 13/31, measures 7,301 feet on asphalt-concrete, and a shorter 05/23 runway runs 3,514 feet, also concrete. All three are paved. This combination of runway lengths supports a wide range of aircraft types operating into Moline.
Does KMLI have customs and border clearance available?
Yes, Quad Cities International Airport has CBP inspection services available onsite, along with a USDA compliance agreement. This means international arrivals can clear customs directly at KMLI rather than diverting to another airport for inspection. There is no distance or reference to a nearest alternate customs airport listed, since clearance is handled on the field itself. Operators should confirm current procedures and any advance notice requirements directly with CBP before planning an international arrival. The presence of a USDA compliance agreement is relevant for flights carrying agricultural cargo or products.
Is fuel available around the clock at KMLI?
Quad Cities International Airport offers 100LL through a self-serve pump located in the T-hangar area, and this pump is open 24 hours a day. Jet A fuel is also available at KMLI, based on the field's listed fuel types, though the remarks do not specify separate self-serve hours for Jet A. The 24-hour self-serve 100LL access is useful for general aviation operators arriving outside staffed hours. KMLI is a towered airport, so pilots should still coordinate ground movement according to tower hours and CTAF procedures when the tower is closed.
What lighting is available at KMLI when the tower is closed?
When the air traffic control tower at Quad Cities International is closed, pilots can activate and increase the intensity of runway and taxiway lighting themselves via CTAF. This includes MALSR approach lighting for both Runway 9 and Runway 27, and REIL identifier lights for Runway 13 and Runway 31. This pilot-controlled lighting system allows continued operations at KMLI outside tower hours without requiring on-field personnel to manage lighting manually. Pilots should use the appropriate CTAF frequency to trigger these systems during off-hours arrivals or departures.
How does business aviation traffic at KMLI vary through the year?
Business aviation traffic at Quad Cities International shows a clear seasonal pattern, concentrated more heavily in the middle of the year according to FAA TFMSC data. July recorded the highest monthly total at 485 operations, while August, despite being adjacent to the peak month, dropped to 283 operations, the lowest of the year. Winter months such as January, February, and November stayed in a narrower band between roughly 306 and 316 operations. Annual business aviation operations at KMLI totaled 4,285 against 18,391 total operations recorded for 2025. This pattern reflects a summer-weighted distribution of business aviation activity at the field.
