Yogurt is treated as a liquid/gel — 3.4 oz or less per container in carry-on, unlimited in checked bags.

Carry-on details
Allowed with conditions. TSA classifies yogurt as a gel-like food because it spreads and has no fixed shape — including regular, Greek, and drinkable yogurt. In carry-on, each container must be 3.4 oz (100 mL) or less and fit in your quart liquids bag. A standard 5.3 oz or 6 oz yogurt cup is too large — buy it after security or pack it in checked baggage instead.
Checked-bag details
Allowed. No size restriction in checked baggage, though yogurt can spoil or leak on a long trip, so pack it well-sealed and expect it to warm up in the cargo hold.
Quantity limit
3.4 oz (per container)
Special instructions
Frozen yogurt that is fully frozen solid at screening is treated like a solid, similar to frozen food — if it's melted or slushy, it counts as a liquid.

FAQ
- Is yogurt considered a liquid by TSA?
- Yes. TSA treats yogurt as a gel-like food under the 3-1-1 liquids rule because it doesn't hold a rigid shape, so each container is limited to 3.4 oz (100 mL) in carry-on.
- Can I bring a full-size yogurt cup in my carry-on?
- No — standard 5.3 oz or 6 oz yogurt cups exceed the 3.4 oz limit. Pack it in checked baggage instead, or buy yogurt after you pass through security.
- Does baby yogurt count under the same rule?
- No. Yogurt intended for an infant or toddler traveling with you is treated like other baby food and is exempt from the standard 3.4 oz limit — declare it for separate screening.
