01The rules in detail
Laptops, tablets and e-readers pass security in the cabin. Standard lanes require them out of the bag in a bin; PreCheck and CT lanes let them stay. Checked luggage: the built-in lithium battery makes many airlines prohibit or discourage it, and theft/damage risk is high. Some routes have had periodic electronics bans in the cabin for security reasons — check advisories for the Middle East and specific countries.
02Tips
- Use a sleeve you can pull out in one motion.
- Back up before you fly; checked laptops are on you if lost.
03Frequently asked

Are the rules the same outside the US?
Mostly similar for liquids and batteries, which follow international standards, but sharp objects, tools, lighters and self-defense items vary widely by country. Check the departure airport's rules and the destination's laws.
TSA and other agencies allow officers to refuse any item they judge unsafe, and rules change. This page summarises published guidance as of the verified date; confirm on tsa.gov or your airport's site before packing anything unusual.
