In standard US lanes, yes — laptops come out in a separate bin. In TSA PreCheck lanes and at airports with newer CT scanners, they can stay in the bag. It varies by lane and airport, so follow the signs and the officer's instructions on the day.
The old rule was blanket: any electronic larger than a phone comes out. That’s changing as scanners improve.
Laptop stays in the bag when:
- You’re in a TSA PreCheck lane.
- The lane has a CT (computed-tomography) scanner — increasingly common at large US hubs and across Europe.
Laptop comes out when: you’re in a standard lane with an older X-ray machine.
The catch is you can’t always tell which scanner you’re at, and it differs terminal to terminal even within one airport. Watch for the signage and listen to the officer — some will tell you to leave everything in. When in doubt, take it out; that’s never wrong.
The same logic applies to liquids: PreCheck and CT lanes usually let the quart bag stay in.

What is the 3-1-1 liquids rule?
Each liquid, gel or aerosol in your carry-on must be in a container of 3.4 oz (100 ml) or less, all fitting in one quart-size (1 litre) clear bag, one bag per passenger. Medications and baby food are exempt but may be inspected. Full answer →
How long does airport security take?
Usually 10–30 minutes, but 45–60+ at large hubs during morning and holiday peaks. Many airports publish live wait times; PreCheck, Fast Track and off-peak departures are the reliable ways to shorten it. Full answer →
Is TSA PreCheck worth it?
If you fly two or more times a year from US airports, yes: shorter lines, shoes and laptops stay put, and many credit cards reimburse the fee. Global Entry costs slightly more and includes PreCheck plus faster US immigration — the better buy for international flyers. Full answer →
