Introduction of Ontario International Airport (ONT)

ONT stands for the IATA Code of Ontario International Airport, which is located about 35 miles east of downtown Los Angeles, the center of Southern California.


The proximity really gives ONT Airport an edge. It is considered as a commercial hub for Southern California. According to FAA (Federal Aviation Administration) data in 2021, the volume of air cargo processed has put Ontario Airport among the top 10 airports in North America, with about 900,000 tons of air freight shipped in and out in a year.

Airfield improvement has always been a focus for ONT Airport. The objective of ONT remains to become the gateway in Southern California through proper planning.


In 2018, FedEx, one of the giant carriers, made an expansion plan for Ontario International Airport, including building a larger sorting center, improving aircraft parking aprons, and upgrading other support facilities. Two years into the project, it was lifted to another high level. A total of four old buildings were demolished to create new ramp space and taxiways for FedEx's new facilities. Besides, FedEx has invested in making automated technology advancements in ONT Airport.


In 2020, Ontario International Airport decided to mitigate space constraints by adding additional areas for air cargo operations into its airfield.


The 2022 Airport Improvement Program released by FAA (Federal Aviation Administration) showed that ONT planned to improve its taxiways and runways and expand the lighting vault inside the airport.


This year (2023), Ontario International Airport has proposed a development plan to build a new international terminal (Dianne Feinstein International Terminal) to improve airport services, grow flight numbers, boost capacity for air cargo flights, and help to zoom in on the European and Asian markets.


What's more, a warehouse construction project led by Amazon has been underway in Ontario. It is reported that the warehouse, or the fulfillment center, will be one of the largest Amazon warehouses in the world. According to the construction plan, the 97-foot-tall, 4.1 million-square-foot structured, and 5-story warehouse is scheduled to be finished in 2024.
