Airport Overview
Lewis University Airport (KLOT/LOT) is a public-use, towered general aviation airport in Romeoville, Illinois, roughly 20 miles southwest of downtown Chicago. It is named for and adjacent to Lewis University, whose well-known aviation program drives much of the field's training traffic, but airport and FBO operations are run by the Joliet Regional Port District. The field handles a busy mix of flight training, corporate, and charter movements.
Runway Capability
KLOT's primary Runway 2/20 is 6,500 ft of grooved concrete, with a 5,500 ft asphalt crosswind runway (9/27). This is a genuinely jet-capable field, not a light-GA-only strip: light jets (Phenom 300, Citation CJ series) and midsize jets (Citation XLS, Learjet 75) operate routinely, and most super-midsize types work with standard temperature and weight planning. Heavy and ultra-long-range jets at high gross weights should run performance numbers or consider a longer alternate.
Charter Considerations
For charter clients, KLOT offers a quieter, faster alternative to O'Hare and Midway for trips serving Chicago's southwest suburbs, Joliet, Naperville, and Will County. The Jet Finder sources FAA Part 135 aircraft positioned near the Chicago area and can compare KLOT against nearby Aurora (ARR) and Chicago Executive (PWK) on positioning cost, runway needs, and ground-time to your final destination.
FBO & Ground Services
A single FBO serves the field, operated by the Joliet Regional Port District under the Fly LOT brand. It provides Jet A and 100LL, hangar storage, ground power, courtesy and rental cars, catering, a conference room, and a crew lounge. Standard hours run 6:00am to 9:00pm with after-hours service available on request, so overnight or early-departure trips should coordinate in advance.
Safety & Planning
KLOT became a towered airport in December 2022 (Lewis Tower, 134.8), adding ATC sequencing to a field with significant training traffic. Pilots should expect a high volume of light singles and twins in the pattern. The two-runway layout gives good crosswind flexibility, and the ILS plus RNAV and VOR approaches support dependable IFR access. There is no on-field U.S. Customs, so international itineraries must clear at a designated port of entry.
Seasonal & Operational Factors
At 679 ft MSL, density-altitude effects at KLOT stay modest even on hot summer afternoons. The main operational variables are Midwest winter weather, frontal passages that can drop ceilings to IFR minimums, occasional freezing precipitation, and summer afternoon convection. Early-morning departures typically see the smoothest conditions, and instrument capability is recommended for reliable year-round scheduling.
Regional Context
KLOT sits within easy reach of several Chicago-area GA fields. Bolingbrook's Clow (1C5) and Joliet Regional (JOT) are closest, while Aurora Municipal (ARR) and Chicago Executive (PWK) offer longer runways and broader FBO options for larger jets. This density of choice lets The Jet Finder optimize each trip on runway capability, FBO service, and drive time to the passenger's actual destination.
