Ontario International Airport says TSA PreCheck use has doubled as it expands screening capacity, highlighting how security infrastructure is becoming part of the passenger experience.
Ontario International Airport, or ONT, said in a release dated August 3, 2026, that TSA PreCheck participation had doubled since the airport introduced onsite Trusted Traveler Programme enrolment kiosks in both terminals in 2024. The share of departing passengers using the programme rose from 13% to 26%, while the airport reported that usage reached as much as half of travellers during some of Terminal 4’s busiest periods. The figures tie a passenger-screening upgrade to a measurable shift in how travellers move through the airport.
The announcement places ONT’s changes within a narrow but important part of air travel: the effort to make airport security more predictable without reducing screening requirements. Ontario International Airport recently expanded the Terminal 2 checkpoint to six lanes, including one primarily dedicated to TSA PreCheck travellers. The release said a similar dedicated lane was scheduled to open as part of the Terminal 4 checkpoint expansion, while noting that operational demands could require flexibility.
ONT began offering expedited TSA PreCheck enrolment and renewal services in both terminals in 2024 through CLEAR, an authorised enrolment provider, according to the release. Travellers can complete the process onsite without an appointment, and existing members can renew at the airport regardless of their original provider. The release also said TSA PreCheck provides expedited screening for eligible travellers, with approximately 99% of members nationwide waiting 10 minutes or less at security checkpoints.
The operational details suggest that the programme is being treated as part of the airport’s broader passenger-flow strategy rather than as a standalone membership service. Dedicated lanes can make the benefit more visible to eligible travellers, while onsite enrolment reduces the separation between signing up for the programme and using it. Ontario International Airport also offers a U.S. Customs and Border Protection Global Entry Enrolment Center, which the release described as one of six such locations in California.
Ontario International Airport is owned and operated by the Ontario International Airport Authority, a joint powers agreement between the City of Ontario and San Bernardino County. The airport serves more than seven million passengers annually and offers nonstop service to two dozen major airports in the United States, Mexico, Central America and Taiwan, according to the release. Its investment in screening capacity therefore frames TSA PreCheck as one element of an airport experience that increasingly depends on both infrastructure and processing convenience.
