Rules & Restrictions for Domestic Air Travel

Learn how to fly in American skies.

Every airline has its own set of rules and regulations, but the Transportation Security Administration and the Federal Aviation Administration give some overall advice about going through airports, security and traveling onboard an aircraft that is valid for all air travel in the United States.

Liquids

Carry liquids into the aircraft cabin in small quantities. The TSA limits passengers to a one-qt. clear plastic bag of 3-oz. or smaller bottles of liquids, gels and lotions.

Identification

All passengers must carry a government-issued photo ID to pass through security checkpoints at airports. Foreign nationals without a permanent residence card or other U.S.-issued ID must travel with their passport within the United States.

Security Checkpoint

Remove your shoes, belts, cell phones and other metal items when crossing through the security checkpoint. Take your laptop and all other electronics out of your carry-on bag and put them through the X-ray machine separately.

Cabin Baggage

Carry-on luggage is generally restricted to a size of 45 inches or less. The number of carry-ons allowed is determined by individual airlines, but the general rule of thumb is one piece of luggage and one personal item.
