LA/Ontario International Airport (IATA: ONT, ICAO: KONT, FAA LID: ONT) (formerly Ontario International Airport) is
a public airport located two miles (3 km) east
of the central business district (CBD) of Ontario, a city in San Bernardino County, California, USA. It is the second major international
airport in the area, after Los Angeles International
Airport (LAX). Ontario International Airport is typically less crowded and easier to use than LAX.
The airport is about 38 miles (61 km) east of downtown Los Angeles, 18 miles (29 km) west of downtown San Bernardino and 14 miles (23 km)
northwest of downtown Riverside. Motorists can use the San Bernardino Freeway (Interstate 10), Ontario Freeway (Interstate 15), or the
Pomona Freeway (State Route 60). It is served by Omnitrans bus route 61 and by private shuttles.
The airport is dominated by Southwest Airlines. LA/Ontario International Airport has 3 terminals. The terminal numbering scheme is designed to
accommodate future growth. The airport's master plan calls for 5 terminals to be spaced adjacent to and in between the existing Terminals 2 and 4.
The "international terminal" (which is a small building designed primarily to segregate arriving international passengers to clear customs) would
be razed and be part of the new Terminal 1. One terminal would be dedicated exclusively to Southwest Airlines and the other to United Airlines,
while the other airlines would share the remaining terminals.
