Minors can go through TSA PreCheck lanes with you, but they do not need their own PreCheck membership and cannot use it alone

A minor traveling with you can walk through the TSA PreCheck security lane if you are enrolled and present your PreCheck ID or boarding pass. The child does not have to be enrolled, does not pay a fee, and does not need their own membership. However, the minor must be physically with you in the lane — they cannot use PreCheck independently or go through a separate PreCheck line by themselves.

TSA rules allow one adult PreCheck member to bring up to two minors through the expedited lane without additional cost. If you are traveling with more than two children, the extra minors go through standard security with another adult or wait for you in the PreCheck lane while you clear security first, then rejoin you afterward.

The minor still needs a valid ID — usually a school ID, passport, or state ID — because TSA screens everyone at the checkpoint, regardless of age or whether they are using PreCheck. PreCheck only speeds up the screening process; it does not waive identification requirements.

Key Takeaways

  • A minor traveling with you can use your TSA PreCheck membership at no extra cost and without their own enrollment.
  • The child must be physically present with you in the PreCheck lane and cannot go through PreCheck alone.
  • You can bring up to two minors through PreCheck with you; additional children go through standard security.
  • The minor still needs a valid ID such as a school ID, passport, or state ID at the checkpoint.
  • PreCheck speeds up screening but does not remove the requirement to show identification or go through a metal detector.

What happens when a minor goes through PreCheck with you

When you enter the TSA PreCheck lane with a minor, you show your PreCheck ID or a boarding pass displaying your PreCheck status. The child walks through with you. Both of you proceed through the expedited screening process, which typically means you can keep shoes, light jackets, and belts on, leave laptops and liquids in your carry-on bag, and move through metal detection faster than the standard line.

TSA officers will still screen the minor — they will walk through the metal detector, may be patted down if the detector alarms, and may have their bag opened for inspection. PreCheck does not exempt anyone from screening; it only removes some of the steps that slow down standard security.

If the minor is very young, TSA allows them to go through the metal detector with you or separately, depending on the child's age and the officer's judgment. Infants and toddlers sometimes do not go through the detector at all if they are held by an adult, but this is at the officer's discretion and varies by airport.

Age limits and who counts as a minor

TSA does not publish a specific age cutoff for who qualifies as a minor under PreCheck rules. In practice, children up to around age 12 or 13 are typically allowed through with an adult, though TSA officers have discretion. Teenagers who look adult-sized or who are traveling alone may be asked to go through standard security instead.

If you are unsure whether your child will be allowed through PreCheck with you, arrive early and ask the TSA officer at the checkpoint before you enter the lane. Officers can tell you on the spot whether the child can proceed with you or needs to go through standard security.

What ID a minor needs at the checkpoint

A minor does not need a government-issued ID in most cases. TSA accepts a school ID, a passport, a state ID, or even a birth certificate for children under 18. Some airports also accept a library card or other institution-issued ID if it has a photo.

If the minor has no ID at all, TSA may still allow them through if they are traveling with an adult who can verify the child's identity. However, this can slow down the process, so bringing some form of ID is faster. A passport is the most widely accepted and works at any airport.

Traveling with multiple children through PreCheck

If you are traveling with three or more children, you can bring only two through the PreCheck lane with you. The third child must go through standard security with another adult, or you can send them through standard security while you take the first two through PreCheck, then meet them on the other side.

Some families split up at security: one parent takes two children through PreCheck while the other parent takes the remaining children through standard security. This works if both parents are present and both have valid IDs. Coordinate with your travel companion beforehand so everyone knows the plan.

If you are the only adult, you will need to choose which children go through PreCheck with you and which go through standard security. Standard security lines are usually longer, so plan your timing accordingly.

PreCheck does not cover international flights the same way

TSA PreCheck speeds up screening for domestic U.S. flights. If you are traveling internationally, your PreCheck benefit applies only to the U.S. portion of your trip — getting to the gate at a U.S. airport. When you return to the United States, PreCheck applies again at the foreign airport's U.S. departure gate, if that airport participates in PreCheck.

Many international airports do not offer TSA PreCheck, so you may go through standard security abroad even if you are enrolled. A minor traveling with you follows the same rules: they can use your PreCheck benefit at participating U.S. airports but not at foreign airports that do not have the program.

What to bring for a minor at the checkpoint

Bring the minor's ID, even if it is just a school ID or passport. Bring your PreCheck ID or a boarding pass showing your PreCheck status. Have the minor's boarding pass ready as well. Some airports scan both the adult's and child's boarding passes to confirm the child is traveling with the PreCheck member.

If the minor is very young and you are carrying them through security, have their ID accessible but keep your hands free to hold the child. TSA officers understand that young children cannot walk through metal detectors on their own and will guide you through the process.

Frequently Asked Questions

Can a teenager use TSA PreCheck alone if their parent is enrolled?

No. A minor cannot use PreCheck without an enrolled adult present. If your teenager is traveling alone, they go through standard security. Once they turn 18 and have their own ID, they can enroll in PreCheck themselves if they want the benefit for future trips.

Do I have to pay extra for my child to use my PreCheck?

No. Minors traveling with an enrolled PreCheck member do not pay a fee and do not need their own membership. PreCheck covers up to two minors per adult at no additional cost.

What if my child does not have an ID?

TSA may allow a child through without ID if an adult can verify their identity, but it is faster to bring something — a school ID, passport, or birth certificate. Check with your airport ahead of time if your child has no ID.

Can my child go through PreCheck if I am not traveling with them?

No. A minor cannot use PreCheck without an enrolled adult physically present in the security lane. If your child is traveling with another adult who is not enrolled in PreCheck, they go through standard security.

Does PreCheck cover my child on the return flight?

Yes, if you are traveling with them. Your PreCheck benefit applies to every flight you take, domestic or international (at participating airports), as long as you show your PreCheck ID or a boarding pass with your PreCheck status. The minor travels with you the same way on the return trip.
