Airport Overview & History
San Gabriel Valley Airport (KEMT) is a 103-acre public general-aviation field within the city limits of El Monte, California, roughly 15 miles east of downtown Los Angeles. Long known as El Monte Airport, the field is owned by Los Angeles County and operated under contract by American Airports Corporation. It is a busy reliever in the crowded LA basin, logging well over 80,000 operations a year — almost entirely general aviation, with significant flight-training and law-enforcement helicopter activity.
Runway Capability
The airport has one runway, 01/19 at 3,995 by 75 feet of asphalt, with a field elevation of 296 feet. That length keeps KEMT firmly in light-aircraft territory: pistons, turboprops and helicopters are the core traffic. Turbine jet use is limited to the smallest very-light jets under favorable conditions, and flight departments operating midsize or larger aircraft should plan on a longer-runway alternate in the region.
FBO & Ground Services
Billion Air Aviation is the on-field FBO, providing full- and self-service Jet A and 100LL around the clock, aircraft ground handling, ramp and tiedown parking, limited hangar space, a passenger terminal and lounge, detailing, rental cars and crew facilities. LA County Aviation administers the airport itself. There are no customs services on the field.
Charter Considerations
For charter clients, KEMT's value is location — it sits in the San Gabriel Valley with quick freeway access to the San Gabriel and east Los Angeles communities, about 15 miles from downtown LA. Because the runway restricts jet types, most charter jet movements in this market route through Van Nuys (KVNY), Hollywood Burbank (KBUR) or Ontario (KONT). The Jet Finder can position a suitable very-light jet to KEMT when the runway permits, or recommend the nearest jet-capable field for your aircraft and payload.
Safety & Planning
Operators should treat the 3,995-foot runway with care: verify aircraft-specific takeoff and landing distances against temperature, weight and runway condition, and remember that the field is tower-controlled on 121.2, not a non-towered CTAF field. The surrounding terrain is benign and field elevation is low, but the short runway leaves little margin for any turbine aircraft. Check NOTAMs and any TFRs over the LA basin before every departure.
Seasonal & Operational Factors
Southern California's mild, dry climate makes KEMT a year-round VFR field for most of the calendar. The main operational variables are summer heat — which raises density altitude and further erodes already-tight runway performance for any turbine aircraft — and the marine-layer low cloud and morning fog common to the LA basin in late spring and early summer, which can drive IFR conditions until it burns off mid-morning.
Regional Context
KEMT sits among the densest concentration of general-aviation airports in the country. Nearby fields include Brackett Field (KPOC) and Fullerton (KFUL) at about 13 nautical miles, Compton/Woodley (KCPM) at 16, and Hollywood Burbank (KBUR) at 17. For jet charter, the practical alternatives are Van Nuys, Burbank and Ontario, all of which offer the runway length and FBO depth that KEMT's short field cannot.
