The short version
| Service | Main purpose | What happens next |
|---|---|---|
| TSA PreCheck | Expedited TSA screening for eligible travelers | Use the PreCheck screening lane when the indicator appears on the boarding pass |
| CLEAR+ | Identity verification at participating airports | Proceed to the applicable TSA screening lane after identity is confirmed |
What TSA PreCheck changes
TSA PreCheck is a federal trusted-traveler program. Eligible passengers use designated screening lanes and generally follow expedited screening procedures. Access depends on the TSA PreCheck indicator appearing on the boarding pass, not simply having a membership number.
What CLEAR changes
CLEAR+ is a private membership service available at participating locations. It verifies identity before the TSA document-check step. After that verification, travelers still complete TSA security screening. The checkpoint, hours, and lane combination available can differ by airport and terminal.
Can you use CLEAR and TSA PreCheck together?
At participating checkpoints, an eligible traveler may use CLEAR for identity verification and then enter the TSA PreCheck screening lane. This can reduce two different queues, but availability is not guaranteed at every terminal or time of day.
Which wait time should you watch?
Use the line that matches your boarding pass and terminal. A short standard line can occasionally move faster than an overloaded expedited lane. AirportWaitTime.com separates Standard, TSA PreCheck, and CLEAR estimates where the source data supports that distinction.
Neither service replaces an airport-arrival plan
Expedited security does not change bag-drop deadlines, parking, terminal transfers, gate distance, or boarding time. Use it as one input in your departure calculation, then confirm current lane availability before leaving.
