Crews are adding two additional screening lanes in Terminal 2 and one in Terminal 4, to give passengers in both terminals six options to clear security.

Crews are also building new security exit corridors for passengers arriving at ONT. Instead of exiting alongside security lanes, we’re building modern, dedicated corridors that will include some fun features!

Family restrooms near the screening areas are also being upgraded to create easier access for people with disabilities.

Timeline: Work began in March 2025 and will be done over 18 months, with an anticipated completion date in fall 2026. If you're traveling during this construction period, we recommend allowing extra time to clear security.

Benefits: Once this project is complete, passengers can expect even faster wait times at TSA security screening areas. New exit corridors will help relieve crowding in the area and make navigation easier for everyone passing through ONT while offering some fun surprises. And nearby family restrooms will be more accessible.
