What Screening Procedures Should You Expect At the IAH Airport?
At George Bush Intercontinental Airport (IAH), security screening is designed to ensure efficiency and safety. The Transportation Security Administration (TSA) uses Advanced Imaging Technology (AIT) as a primary method of detecting concealed threats such as weapons, explosives, or prohibited items hidden under clothing. This technology provides a detailed scan of a passenger’s image, helping agents identify potential risks more accurately.
While travelers may decline AIT in favor of a physical screening, TSA regulations require certain passengers to undergo AIT. This ensures compliance with federal security standards and maintains consistent safety measures across all checkpoints.
Enhanced Pat-Downs:
TSA agents may perform enhanced pat-downs at random or upon a passenger’s request instead of AIT. Agents explain each step before beginning, and passengers can ask for a private screening room if they prefer not to undergo the procedure in public.
Modified Pat-Downs for Children:
For passengers aged 12 and under, TSA offers a gentler, modified pat-down to minimize discomfort while still maintaining security.
Passenger Choice:
Travelers always retain the right to request alternative screening methods, ensuring flexibility and transparency in the process.
These procedures reflect TSA’s commitment to balancing strict security standards with passenger comfort and dignity.
What Is the TSA 3-1-1 Liquids Rule?
The TSA’s 3-1-1 rule is strictly enforced at IAH. Passengers may carry a quart-sized bag of creams, aerosols, gels, liquids, and pastes through security checkpoints. Each item must be 3.4 ounces or 100 milliliters or even less than that.
This rule is designed to limit the amount of liquid substances carried onboard, reducing potential risks while still allowing travelers to bring essential items. Common examples include toiletries such as shampoo, toothpaste, and lotion.
- Bag Requirement: All items must fit comfortably inside a quart-sized, transparent, resealable plastic bag.
- Exceptions: Certain medically essential liquids, baby formula, and breast milk may be permitted in larger quantities, but they must be declared to TSA officers at the checkpoint.
- Additional Guidance: For a complete list of prohibited items and travel tips, passengers can visit the official TSA Travel Tips website or call the TSA Contact Center at 1-866-289-9673.
By following the 3-1-1 rule, travelers can move through security more smoothly and avoid unnecessary delays.
