If you are flying from Chicago O’Hare International Airport (ORD), checking the latest ORD Security Wait Times before leaving for the airport can help you decide how much time to allow for check-in, baggage drop, TSA screening, and getting to your gate.
O’Hare is one of the busiest airports in the United States, with four passenger terminals and multiple TSA checkpoints. Security conditions can change throughout the day depending on passenger volume, checkpoint operations, staffing, and travel demand. O’Hare provides current TSA checkpoint information and recommends that travelers check airport and airline information before their trip.
What Are ORD Security Wait Times?
ORD Security Wait Times refer to the amount of time passengers may need to spend waiting at a Transportation Security Administration (TSA) checkpoint before entering the secure airport area.
Unlike a fixed schedule, security lines at O’Hare can change during the day. A checkpoint that is moving quickly in the morning may become considerably busier later, while another checkpoint may have shorter lines.
Your total security experience can include:
- Waiting in the TSA line
- Travel document verification
- Carry-on baggage screening
- Personal screening
- Additional inspection if required
- Walking from the checkpoint to your departure gate
The displayed or reported wait time should therefore be treated as an estimate rather than a guarantee.
How Can You Check ORD Security Wait Times?
The most reliable way to check current O’Hare security conditions is to use the airport’s official TSA/security information before leaving for ORD.
O’Hare provides information about TSA checkpoint operations, including checkpoint locations, operating hours and TSA PreCheck availability. Checkpoint hours can be affected by day-to-day airport operations, so travelers should verify the information for their travel date.
Official O’Hare Security Information: Check current ORD TSA information
When checking security information, pay attention to:
- Your departure terminal
- Available TSA checkpoint
- Checkpoint operating hours
- TSA PreCheck availability
- CLEAR availability
- Your airline’s current departure information
Which Terminals Have TSA Checkpoints at ORD?
Chicago O’Hare has four passenger terminals: Terminal 1, Terminal 2, Terminal 3 and Terminal 5. TSA screening is available at checkpoints within these terminals.
Here is a simplified overview of the current checkpoint locations:
| Terminal | TSA Checkpoints |
|---|---|
| Terminal 1 | CP1, CP2, CP3 |
| Terminal 2 | CP5 |
| Terminal 3 | CP6, CP7, CP7A, CP8 |
| Terminal 5 | CP10 |
Checkpoint operating hours vary. For example, O’Hare currently lists CP10 in Terminal 5 as operating 24 hours, while the other checkpoints have specific opening and closing times.
Because checkpoint schedules can change, do not assume that every checkpoint will be open when you arrive.
What Time Is ORD Security Usually Busiest?
There is no single daily period when every O’Hare checkpoint will have the longest line.
Passenger volume can change based on:
- Morning departure banks
- Afternoon and evening flights
- Weekends
- Holidays
- Summer travel
- Thanksgiving and Christmas periods
- Major events in Chicago
- Airline schedule changes
- Number of TSA lanes operating
O’Hare has previously warned travelers that TSA and CBP wait times can become longer than usual during major holiday travel periods and provides real-time TSA checkpoint information through its airport website.
For that reason, it is better to check the latest checkpoint information for your actual travel day instead of relying on a single “average” wait time.
How Early Should You Arrive at ORD?
Your ideal arrival time depends on your flight, terminal, baggage situation, parking or transportation, and whether you are traveling domestically or internationally.
A useful planning approach is:
| Travel Situation | Planning Consideration |
|---|---|
| Domestic flight | Allow enough time for check-in, baggage, TSA and walking |
| International flight | Allow additional time for airline and document procedures |
| Checked baggage | Arrive earlier than a carry-on-only traveler |
| Holiday travel | Build in an additional time buffer |
| First visit to ORD | Allow extra time for navigation |
| TSA PreCheck | Use the applicable PreCheck checkpoint |
| Late-night/early flight | Verify checkpoint operating hours |
| Family travel | Allow additional time for screening |
The airport itself advises travelers to plan ahead and check their airline’s operations for the day of travel.
The important point is that TSA wait time is only one part of your airport journey.
ORD TSA Checkpoint Hours
O’Hare currently lists different operating schedules for individual checkpoints.
| Terminal | Checkpoint | General Hours Listed by ORD |
|---|---|---|
| Terminal 1 | CP1 | 3:30 AM–11:00 PM |
| Terminal 1 | CP2 | 4:00 AM–8:30 PM |
| Terminal 1 | CP3 | 3:45 AM–8:00 PM |
| Terminal 2 | CP5 | 3:15 AM–11:00 PM |
| Terminal 3 | CP6 | 3:45 AM–8:00 PM |
| Terminal 3 | CP7 | 3:30 AM–8:00 PM |
| Terminal 3 | CP7A | 3:30 AM–10:30 PM |
| Terminal 3 | CP8 | 4:00 AM–8:30 PM |
| Terminal 5 | CP10 | 24 hours |
O’Hare notes that these schedules are general checkpoint hours and can be affected by daily airport operations. Travelers should check the latest information before their trip.
Can You Use Another ORD Security Checkpoint?
It depends on your terminal and the circumstances of your trip.
O’Hare’s terminals have different checkpoint locations, and passengers should normally use the security checkpoint serving their departure terminal.
Terminals 1, 2 and 3 are connected within the airport system, while Terminal 5 is separate from the domestic terminal complex. O’Hare provides the Airport Transit System and Terminal Transfer Bus for certain terminal connections.
This means you should not automatically choose a checkpoint simply because it appears to have a shorter line. Consider:
- Your departure terminal
- Whether the checkpoint is open
- Your airline
- TSA PreCheck availability
- CLEAR availability
- How you will reach your gate afterward
ORD TSA PreCheck Wait Times
TSA PreCheck is available at designated O’Hare checkpoints for eligible travelers.
O’Hare’s current TSA information lists PreCheck availability at:
- Terminal 1 — CP2
- Terminal 2 — CP5
- Terminal 3 — CP7A
- Terminal 5 — CP10
The airport notes that PreCheck hours can differ from the standard checkpoint operating hours.
TSA PreCheck can make the screening process more streamlined for eligible passengers, but it does not guarantee a completely line-free experience.
During busy travel periods, PreCheck passengers may still encounter a queue.
Does ORD Have CLEAR?
Yes. CLEAR services are available at O’Hare, including locations in the domestic terminals and Terminal 5.
O’Hare has specifically listed CLEAR lanes in Terminals 1 and 2, while CLEAR services are also available in Terminal 5.
CLEAR and TSA PreCheck are separate programs. Some travelers may have access to both.
If you use CLEAR, check the current location and operating hours before heading to the airport because services can change.
What Can Make ORD Security Lines Longer?
Several factors can affect how quickly TSA lines move at O’Hare.
1. Number of Passengers
When large numbers of passengers arrive around the same time, TSA checkpoints can become crowded.
This is especially relevant when several flights are scheduled close together.
2. Open Screening Lanes
The number of active TSA lanes can affect how quickly passengers move through security.
A checkpoint may become faster when additional screening capacity becomes available, while a temporary reduction in lanes can increase the wait.
3. Carry-On Baggage
Bags containing prohibited or restricted items can require additional inspection.
O’Hare advises passengers to check TSA rules and pack carry-on luggage properly to help avoid unnecessary delays.
4. Identification Problems
Passengers should have their identification and boarding information ready when approaching the document-checking area.
O’Hare currently provides information about TSA ConfirmID for travelers who do not present an acceptable form of identification.
5. Holiday Travel
Large travel periods can produce heavier passenger demand.
O’Hare has specifically advised travelers to expect potentially longer TSA and CBP waits during major holiday periods.
6. Terminal Transfer Time
If your trip involves moving between terminals, the time spent getting to the correct terminal can become part of your overall airport journey.
O’Hare operates the Airport Transit System and a Terminal Transfer Bus for certain connections.
How Long Should You Allow for ORD Security?
There is no single wait time that applies to every passenger at O’Hare.
Your actual experience can depend on:
- Departure terminal
- Time of day
- Passenger volume
- TSA staffing and lane availability
- Travel date
- Checked baggage
- Security procedures
- TSA PreCheck or CLEAR eligibility
- Additional screening requirements
Because of these variables, it is safer to plan your airport arrival around your entire journey, rather than adding a fixed number of minutes to your flight departure time.
ORD Security Wait Times for International Flights
International travelers should allow additional time because the airport process can involve airline document checks, baggage procedures and security screening.
If you are departing internationally from ORD, check your airline’s terminal and recommended check-in time before traveling.
Terminal 5 handles many international operations, although some international services operate from other terminals depending on the airline and flight. O’Hare has four passenger terminals and provides airline-specific terminal information.
For passengers arriving internationally and connecting to another flight, the process can be more complicated.
Passengers arriving on an international flight generally need to clear U.S. Customs and Border Protection, collect checked baggage when required, and then complete TSA screening before continuing to a domestic connection.
What Happens If You Have an International Connection at ORD?
The process depends on where your international flight originated and whether you are connecting onward.
For many international arrivals, passengers must:
- Arrive at the appropriate terminal.
- Complete CBP immigration processing.
- Collect checked baggage when required.
- Recheck baggage if necessary.
- Travel toward the connecting terminal.
- Complete TSA screening again.
- Continue to the departure gate.
O’Hare states that passengers arriving from international destinations generally must clear CBP and that connecting travelers may need to go through TSA screening again.
Does ORD Security Operate 24 Hours?
Terminal 5 Checkpoint CP10 is currently listed as operating 24 hours.
The other O’Hare checkpoints have specific opening and closing times. For example, Terminal 1 CP1 is listed until 11:00 PM, Terminal 2 CP5 until 11:00 PM, and several Terminal 3 checkpoints close earlier.
Because operating schedules can change due to airport conditions, travelers with very early or late flights should verify the checkpoint information before traveling.
Tips for Getting Through ORD Security Faster
You cannot control the number of people in the TSA line, but you can reduce avoidable delays.
Check ORD Security Information Before Leaving
Look at the latest O’Hare TSA information before you start your journey.
This can help you identify your terminal and confirm whether the relevant checkpoint is operating.
Keep Your ID Ready
Have your acceptable identification available before reaching the TSA document-checking area.
This avoids unnecessary searching while other passengers are being processed.
Organize Your Carry-On
O’Hare advises travelers to pack smart and avoid prohibited items.
Check TSA’s current rules for liquids, electronics and other restricted items before packing.
Follow the 3-1-1 Liquids Rule
Liquids, gels, aerosols, creams and pastes generally need to follow TSA’s 3-1-1 requirements.
Oversized or prohibited liquids can lead to additional screening and delays.
Keep Boarding Information Accessible
Have your boarding pass and travel documents ready before reaching the checkpoint.
Consider TSA PreCheck
Eligible travelers may use TSA PreCheck at participating ORD checkpoints.
Check the current PreCheck operating hours before selecting your route through the airport.
Give Yourself More Time During Busy Travel Periods
A short security wait earlier in the day does not guarantee that the same condition will continue.
Extra time is especially useful during holidays and high-volume travel periods.
What ID Do You Need at ORD Security?
TSA requires travelers to present acceptable identification at security checkpoints.
O’Hare currently provides information about REAL ID and TSA ConfirmID. Starting February 1, 2026, O’Hare’s TSA information states that passengers without acceptable identification may use TSA ConfirmID as a fee-based identity-verification option, subject to the applicable requirements.
Travelers should verify current identification requirements before leaving for the airport.
Can a Security Checkpoint Close During the Day?
Yes. O’Hare explains that checkpoint hours are subject to day-to-day airport operations.
This is particularly important if you have a very early departure or a late-night flight.
Instead of assuming a checkpoint will be available, verify its current operating schedule before arriving.

Final Thoughts on ORD Security Wait Times
Checking ORD Security Wait Times before leaving for Chicago O’Hare can make your airport planning easier. O’Hare has multiple TSA checkpoints across Terminals 1, 2, 3 and 5, and their operating hours can differ.
Rather than planning around one fixed TSA wait time, consider the complete journey: getting to the airport, parking or transportation, airline check-in, baggage drop, TSA screening, terminal navigation and reaching your gate.
For the most useful information on the day of your flight, check the current O’Hare TSA information, confirm your terminal with your airline, prepare your identification and carry-on baggage, and leave enough time for conditions that may change after you arrive.
