Protein Bars
Protein bars are solid food, so they're allowed in carry-on and checked baggage with no restriction.

Carry-on details
Allowed. Protein bars are solid food, not a liquid or gel, so the 3-1-1 rule doesn't apply. Pack them in the wrapper or a snack bag and they'll screen normally with the rest of your carry-on.
Checked-bag details
Allowed. Protein bars can be packed in checked baggage without restriction.
Special instructions
Bars with a soft, syrupy, or gel-like filling that oozes rather than holding its shape can sometimes be flagged as a gel — stick to standard chewy or crunchy bars for the smoothest screening.
FAQ
- Do protein bars count as a liquid or gel at security?
- No. A standard protein bar is solid food and isn't subject to the 3.4 oz liquids rule. Only very soft, syrupy, or gel-filled bars occasionally draw extra attention.
- Can I bring a whole box of protein bars in my carry-on?
- Yes. There's no quantity limit on solid snack food like protein bars in either carry-on or checked bags.
