Traveling can be stressful, especially when navigating a major hub like Chicago O’Hare International Airport (ORD). For passengers flying with United Airlines, understanding the layout, rules, and best practices at security checkpoints within the United Airlines Chicago Ohare Airport Terminal can save both time and hassle. Whether you're a seasoned traveler or a first-time flyer, this comprehensive guide provides everything you need to make your journey through the airport’s security smooth and efficient.

Introduction to United Airlines at O’Hare

United Airlines operates primarily out of Terminal 1 at Chicago O’Hare, which is one of the airport’s busiest and most iconic terminals. Terminal 1 houses Concourses B and C, which are interconnected via an underground tunnel and serve both domestic and international flights. Knowing your way around this terminal is crucial, especially when facing tight schedules or long lines at the security checkpoint.

1. Understanding Terminal 1 Layout

Before discussing the security specifics, it's essential to grasp the layout of the United Airlines Chicago O’Hare Airport Terminal.

• Concourse B is home to the main security checkpoint and numerous gates.

• Concourse C, mainly for international and long-haul flights, is accessible via the pedestrian tunnel.

• The Terminal 1 ticketing level features the United check-in counters, Premier Access lanes, and baggage drop.

Familiarity with these areas helps in selecting the correct security lane and navigating to your gate quickly.

2. When to Arrive at the Airport

Time management is everything when flying out of a major hub like O’Hare.

• Domestic Flights: Arrive at least 2 hours prior to departure.

• International Flights: Arrive 3 hours in advance to allow time for security and customs checks.

Peak times (early morning, weekends, and holidays) can cause significant delays, so always factor in additional time.

3. Choose the Right Security Lane

At the United Airlines Chicago O’Hare Airport Terminal, you’ll find several options to pass through security. Choosing the right one can save you time and stress.

Regular Security Lane

This is for general travelers who do not have access to expedited services. Be prepared to remove:

• Shoes

• Belts

• Jackets

• Laptops and liquids from bags

TSA PreCheck Lane

TSA PreCheck allows eligible passengers to:

• Use a faster, less intrusive screening lane

Apply for TSA PreCheck in advance to benefit at Terminal 1.

United Premier Access Lane

Exclusively for:

• United Premier members

• Business and First-Class passengers

• Star Alliance Gold status holders

This lane is often shorter and faster than the general line.

4. Use CLEAR for an Even Faster Experience

United Airlines partners with CLEAR, a biometric identity verification service that speeds up the ID check process. CLEAR members can bypass long ID lines and proceed straight to the screening area. At Chicago O’Hare, CLEAR lanes are available at Terminal 1, and enrollment is quick and easy.

5. Preparing for Security: What to Pack and What to Avoid

Follow the TSA 3-1-1 Rule:

Pack your carry-on so these items are easily accessible to avoid delays.
