Expedited Screening Program

Travelers have two options with programs that are designed to move you through security screening lines faster. You must sign up with the program administrator in advance.

TSA Pre✓

  • TSA Pre✓is designed to enhance and expedite security by placing more focus on pre-screening individuals who volunteer information about themselves prior to flying. Eligible participants include certain frequent flyers invited from participating airlines (Alaska Airlines, American Airlines, Delta Air Lines, Southwest, and United Airlines ) as well as members of the U.S. Customs and Border Protection’s (CBP) Trusted Traveler programs (Global Entry, SENTRI and NEXUS) who are U.S. citizens and fly on a participating airline. Ontario International Airport has designated TSA Pre✓ screening lanes located at the both check points.
  • Through the TSA Pre✓ vetting process, information is embedded in a barcode on your boarding pass. This information alerts TSA agents that you are eligible for expedited screening. Benefits include not having to remove your shoes, 3-1-1 compliant liquids/gels bag from carry-on, laptops from bag, light outerwear/jackets and belts.

Be advised The TSA incorporates random and unpredictable security measures throughout the airport.

Global Entry

  • Global Entry is a U.S. Customs and Border Protection (CBP) program that allows expedited clearance for pre-approved, low-risk travelers upon arrival in the United States
  • Global Entry members are processed by biometric identification in less than five minutes at kiosks.
  • Global Entry is intended for frequent international travelers although there is no minimum number of trips necessary to qualify for the program
