Baby formula on a plane

Allowed, with conditions

Short answer: Under TSA and FAA rules: yes, in carry-on and checked bags (reviewed 2026-10-27).

These are the reviewed rules for a baby formula on flights departing the United States. Each rule is listed as its official source states it, with the date we last reviewed it. A rule from security screening, from the dangerous goods regulations and from your airline can all apply at once, and you need to meet every one of them.

Before you pack baby formula

Use this list with your actual item and itinerary. It summarizes the current source-reviewed entries below; it does not replace the complete conditions or the airline's instructions.

  1. Check the reviewed Carry-on bag and Checked bag rules below. If a bag type is not listed, that does not mean it is allowed: verify it with the airline and relevant authority.
  2. Confirm the operating airline, connecting airports and destination rules. This site does not verify destination customs or quarantine restrictions.
  3. Recheck the linked official sources shortly before departure; published guidance and your flight circumstances can change.

What you need to know about your baby formula

The rules above do not depend on details of the item.

Commonly confused

  • Allowed in a carry-on bag does not mean allowed in a checked bag. The rules for each are listed separately above.
  • Security screening (TSA) and dangerous goods rules (FAA) are different rules. An airline can also set stricter limits. Where a source has no rule for a case, we say so instead of guessing.
  • Airline rules come from the airline that operates the flight, which can differ from the one you booked with.
  • Being allowed on board does not mean the item is allowed into your destination. Customs rules are not covered.
