Carry-on details
Allowed. Diapers are a solid personal item, not a liquid or gel, so there's no 3.4 oz limit or quantity cap — pack as many as you need for the trip.
Checked-bag details
Allowed. No restrictions in checked baggage.
Special instructions
A packed bag of diapers may prompt a closer look or a swab test at the X-ray, since large soft packages can obscure the view of other items — this is routine and not specific to diapers.
FAQ
- Is there a limit on how many diapers I can bring?
- No. Diapers are a solid item exempt from the 3-1-1 liquids rule, so TSA doesn't limit the quantity in carry-on or checked baggage.
- Are diapers different from baby wipes for TSA purposes?
- They're treated the same way — both are solids with no quantity restriction — but they're separate products. Wipes are moist and used for cleaning; diapers are the absorbent garment itself.
