Ground corridor

• The Inland Empire corridor presents a low-to-moderate opportunistic property crime environment typical of suburban Southern California
• no active civil unrest or movement restrictions affect the airport vicinity. The airport sits approximately 2 miles east of downtown Ontario with straightforward freeway access via I-10 and I-15
• no high-risk travel corridors are identified between the airport and primary Inland Empire or Greater Los Angeles destinations. App-based ride-share and regulated taxi services operate from designated curbside zones at both terminals and are generally reliable for routine travel, with pre-arranged vehicles or vetted transport recommended for executives or late-night movements. The United States carries no comprehensive embargo, travel ban, or armed-conflict designation
• no elevated diligence beyond standard situational awareness is required.

The U.S. State Department rates travel at Level 1 (Exercise Normal Precautions), while the UK FCDO assigns its lowest advisory tier, noting that terrorists are considered very likely to attempt attacks.
