Diaper Bag
Diaper bags are allowed as carry-on or checked, and the liquid baby items inside are exempt from the standard 3.4 oz rule.

Carry-on details
Allowed. A diaper bag goes through security like any other carry-on bag. Most of what's inside — breast milk, formula, baby food and snacks, bottles, and sippy cups — is exempt from the standard liquids rule, so those don't need to fit in 3.4 oz containers. Some airlines also let a diaper bag count as an extra item beyond your usual carry-on and personal item allowance — that's an airline policy, not a TSA rule, so confirm with your carrier.
Checked-bag details
Allowed. You can check a diaper bag like any other bag, though keeping it with you in the cabin is recommended for easy access to diapers, wipes, and feeding supplies during the flight.
Special instructions
Place the diaper bag's baby food, formula, and breast milk items in a bin for separate X-ray screening, and tell the officer if you don't want them opened or X-rayed.

FAQ
- Does a diaper bag count as my carry-on or personal item?
- TSA doesn't set that rule — it's airline-specific. Many airlines let parents bring a diaper bag as an additional item beyond the standard carry-on and personal item allowance, so check with your airline before you fly.
