At just 3.7km (2.3 miles) east of downtown Ontario, Ontario International Airport  is a small but well-equipped alternative to Los Angeles Airport and John Wayne Airport for passengers flying to California.

The number of flights to Ontario International Airport has been declining steadily in recent years (there were 4.8 million passengers in 2010, but the terminals are built to handle twice that) – some say due to the lack of direct flights to major destinations, in comparison with other airports nearby. However, those who use the airport agree that it is a convenient alternative, well connected to nearby air fields and towns, easy to get in and out of, clean and with good basic facilities.
