Airport Security With a Cat or Dog: TSA Screening in 4 Steps

This guide covers airport security at TSA (Transportation Security Administration) checkpoints in the US. Security at overseas connections follows that country’s rules.

What does TSA do with pets at the checkpoint?

TSA screens the pet and the carrier separately: the carrier through the X-ray, the pet with you through the walk-through detector, followed by a hand swab. TSA’s local press releases^[1] (2022–2023) describe the same steps each time:

1. Bring your pet to the checkpoint in a hand-held travel carrier.
2. Take your pet out of the carrier just before screening begins.
3. Put the empty carrier on the belt for X-ray.
4. Carry your pet through the walk-through metal detector, or walk it through on a leash.
5. An officer swabs your hands to check for explosive residue.
6. Put your pet back in its carrier away from the checkpoint, in the re-composure area (TSA’s name for the space past the checkpoint where you repack).

TSA has repeatedly warned that pets have been sent through checkpoint X-ray machines inside bags. They should never be. JetBlue’s own security guidance says the same: you’ll be asked to hold your pet while the carrier is inspected, and your animal will never be placed in the X-ray machine. If you can’t hold your pet through screening, it will get a secondary screening, including a visual and physical inspection (JetBlue^[2], checked October 30, 2026).

Step 1: Practice the sequence at home

Rehearse who holds the pet and who handles the bags, and make sure your pet is used to its harness before travel day. At the checkpoint, you’ll be handling a loose animal, an empty carrier, your bags and your shoes all at once.

• Keep documents in one small pocket you can reach easily.
• Cut down loose items: fewer bins means less juggling.
• Fit a secure harness at home, days ahead. Don’t put on unfamiliar gear for the first time in the queue.
• If you’re traveling alone, decide in advance what goes on the belt first.

Step 2: Tell the officer before you open the carrier

Let the TSA officer know you have a dog or cat, and mention any escape or handling concern, before you touch a zip. TSA has said in press releases^[3] that owners worried their pet might run can ask for private screening with the pet.

A request you can use:

“I have a cat in this carrier and she may bolt if I take her out here. Could we do the screening in a private area, please?”

Private screening is a request. TSA doesn’t promise a room at every checkpoint. A public 2025 question from a cat owner asking how to request a private screening room shows that many owners aren’t sure how it works (traveler question, r/tsa^[4]). It’s an individual post, not a description of official procedure. Ask early, and allow extra time.

Step 3: Follow the officer’s instructions

Keep hold of your pet the whole time, and follow the officer’s directions on harnesses, leashes and equipment. Don’t take off any restraint unless an officer tells you to.

• Hold your pet securely, close to your body.
• If an officer asks you to take something off, ask how to do it safely before you do.
• If the handling being suggested looks unsafe for your pet, explain why and ask for another option before going ahead.
• Don’t open several zips at once while balancing bags, and never let an anxious animal loose on the floor.

Step 4: Put your pet back in the carrier away from the busy area

After screening, go to the re-composure area, get your pet back in the carrier and check the closures before you gather anything else. That’s TSA’s guidance too^[1]. It’s safer for your pet and for the travelers around you.

Then:

1. Check every zip and clip.
2. Count your belongings.
3. Check how your pet is doing.
4. Find your route to the gate, and check whether the relief area is inside security. Leaving means screening again. See our pet layover and connection guide.

What about pet food, water and medication?

Check TSA’s current rules for the exact items and amounts you plan to carry, and keep any prescribed medication in its labeled packaging. We can’t promise any particular pet product will be allowed through. Bring an empty bowl and fill it after security.

Example: traveling alone with an anxious cat

Hypothetical example. A solo traveler keeps documents in one zipped pocket and packs everything else into a single carry-on. In the queue, they tell the TSA officer about the cat before touching the carrier and ask for private screening. While they wait, they put their bag and shoes on the belt. In the private area, they take the cat out with its harness already fitted, hold it while the carrier is screened, and put it straight back in before collecting their things.

None of this guarantees a calm cat, and facilities vary by airport. But the traveler isn’t making it up on the spot.

Before you get to the airport

Make sure your carrier meets your airline’s rules and your pet is used to it. Airport security is easier when the carrier is familiar. See how to measure your pet and choose a carrier. If your pet seems unwell before or during travel, see how to find a vet abroad for emergency planning.

Frequently asked questions

Does my pet go through the X-ray machine? No. The empty carrier is X-rayed, and your pet goes through the walk-through detector with you, in your arms or on a leash.

Can I ask for a private screening room for my cat? Yes. TSA says owners worried^[3] about their pet running away can ask for a private screening. Ask the officer before you open the carrier. Availability can vary.

Do I have to take my pet out of the carrier? In the standard process, yes. If you can’t hold your pet, JetBlue’s guidance describes^[2] a secondary screening with a visual and physical inspection. Ask the officer what options there are.

Does this apply at an airport abroad? No. TSA procedures apply at US checkpoints. Elsewhere, follow the local airport security authority’s instructions.

Should I sedate my pet for security? Talk to your vet and the airline beforehand. The AVMA advises^[5] consulting your veterinarian before giving any sedative or tranquilizer, and notes that airlines generally don’t allow sedated pets. Never improvise a dose at the airport.
