Introduction: Choosing the Right Airport Security Program in the USA
Airport security lines are one of the most frustrating parts of air travel in the United States. Long waits, document checks, and secondary screening can easily add stress and unpredictability to even the most carefully planned trip. To address this, several airport security programs exist to help travelers move through airports faster — most notably TSA PreCheck, CLEAR, and Global Entry.

While these programs are often mentioned together, they are not interchangeable. Each serves a different purpose, works at different points in the airport journey, and delivers value depending on how often — and where — you travel.
This in-depth guide compares TSA PreCheck vs CLEAR vs Global Entry to help frequent flyers, business travelers, and high-income travelers determine which program is best based on cost, airport availability, travel patterns, and real-world performance.
Understanding Airport Security Programs in the USA
Airport security programs in the United States are designed to reduce congestion and improve efficiency while maintaining federal security standards. They do this in two fundamentally different ways:
- Identity verification acceleration
- Security screening acceleration
Understanding this distinction is critical before comparing programs.
Identity vs Screening: What Each Program Actually Does
| Function | TSA PreCheck | CLEAR | Global Entry |
|---|---|---|---|
| Identity verification | ❌ | ✅ | ❌ |
| Security screening | ✅ | ❌ | ✅ (via PreCheck) |
| Immigration processing | ❌ | ❌ | ✅ |
- TSA PreCheck speeds up the security screening process.
- CLEAR speeds up identity verification before screening.
- Global Entry speeds up US immigration and includes TSA PreCheck.
Quick Overview: TSA PreCheck, CLEAR, and Global Entry
| Program | Best For | Primary Benefit |
|---|---|---|
| TSA PreCheck | Domestic frequent flyers | Faster security screening |
| CLEAR | Travelers at busy hub airports | Skip ID check lines |
| Global Entry | International travelers | Faster re-entry + PreCheck |
Each program targets a different bottleneck in the airport journey.
What Is TSA PreCheck?
TSA PreCheck is a trusted traveler program run by the Transportation Security Administration. It allows approved travelers to use expedited security lanes at participating US airports.

TSA PreCheck Benefits
| Benefit | Description |
|---|---|
| Shoes stay on | No removal required |
| Laptops stay in bag | Faster throughput |
| Liquids stay in bag | No 3-1-1 removal |
| Dedicated lanes | Shorter lines |
Important limitations:
- TSA PreCheck does not guarantee zero wait
- Travelers can still be randomly selected for standard screening
- Not every checkpoint has PreCheck lanes open at all times
What Is CLEAR?
CLEAR is a private biometric identity verification service that operates at select US airports. It does not replace TSA screening — instead, it allows members to skip the standard ID check line.



How CLEAR Works
- Biometric verification (fingerprints or eye scan)
- Identity confirmed digitally
- Member escorted to front of TSA screening
CLEAR works best when paired with TSA PreCheck, allowing travelers to bypass both ID checks and standard screening lines.
What Is Global Entry?
Global Entry is a trusted traveler program run by U.S. Customs and Border Protection. It is primarily designed for international travelers returning to the US.


Key Global Entry Benefits
| Feature | Benefit |
|---|---|
| Immigration kiosks | Skip long customs lines |
| Biometric verification | Faster re-entry |
| TSA PreCheck included | Domestic benefit |
Global Entry automatically includes TSA PreCheck, making it one of the best value programs for international travelers.
TSA PreCheck vs CLEAR vs Global Entry: Full Comparison
| Feature | TSA PreCheck | CLEAR | Global Entry |
|---|---|---|---|
| Application cost | Low | High | Medium |
| Renewal period | 5 years | Annual | 5 years |
| Domestic benefit | ✅ | ✅ | ✅ |
| International benefit | ❌ | ❌ | ✅ |
| Includes PreCheck | ❌ | ❌ | ✅ |
| Biometric data used | ❌ | ✅ | ❌ |

Cost Breakdown & Real Value
| Program | Fee | Effective Cost per Year |
|---|---|---|
| TSA PreCheck | Low | Very low |
| CLEAR | High | High |
| Global Entry | Medium | Low |
Many premium travel credit cards reimburse:
- TSA PreCheck
- Global Entry
- CLEAR (sometimes partially)
For frequent travelers, reimbursement can reduce the real cost to $0.
Eligibility & Background Checks
| Requirement | TSA PreCheck | CLEAR | Global Entry |
|---|---|---|---|
| Background check | ✅ | ❌ | ✅ (strict) |
| US citizens eligible | ✅ | ✅ | ✅ |
| Non-US citizens | Limited | ✅ | Limited |
| Criminal disqualifiers | Yes | No | Yes |
Global Entry has the strictest vetting and can be revoked for customs violations.
Enrollment Process Compared
TSA PreCheck Enrollment
- Online application
- In-person appointment
- Approval in days to weeks
CLEAR Enrollment

Airport Availability & Coverage
| Program | Airport Coverage |
|---|---|

CLEAR is not available everywhere, which limits its usefulness for travelers who frequently use smaller airports.
Airport-Specific Performance Differences
Large Hub Airports (JFK, LAX, ATL, ORD)
- CLEAR provides the biggest benefit
- PreCheck lines can still be long
- Stacking CLEAR + PreCheck saves the most time
Medium Airports
- TSA PreCheck often sufficient
- CLEAR value inconsistent
Small & Regional Airports
- CLEAR rarely available
- TSA PreCheck offers limited advantage
- Global Entry only helps on return from abroad
Can You Use TSA PreCheck, CLEAR, and Global Entry Together?
Yes — and many frequent flyers do.
| Traveler Type | Best Combination |
|---|---|
| Domestic frequent flyer | PreCheck + CLEAR |
| International business traveler | Global Entry |
| Hub-to-hub flyer | All three |
Stacking programs addresses every major bottleneck in the airport journey.
