📘 Overview of domestic requirements

Travelers on domestic flights within the United States must follow TSA regulations, present approved identification, comply with baggage rules, and meet airport security standards. These requirements ensure safe and efficient air travel nationwide.

👮 TSA identification requirements

All passengers 18 and older must show a valid ID at security. Approved forms of identification include:

• State-issued driver’s license or identification card
• REAL ID-compliant identification
• U.S. passport or U.S. passport card
• Trusted Traveler Program cards

See the official TSA page for the full list: tsa.gov

✈️ REAL ID requirements

REAL ID enforcement requires travelers to present a compliant form of identification when passing through airport security. Check for the star symbol on your driver’s license or ID card to confirm compliance.

💼 Baggage rules for domestic flights

Baggage policies are set by each airline. Common requirements include:

• Carry-on limits and size restrictions
• Checked bag weight limits (usually 50 lbs per bag)
• Standard fees for checked luggage
• Liquids limited to 3.4 oz / 100 ml per container in carry-on bags

Review airline-specific policies before traveling to avoid unexpected charges.
