Salad Dressing
Salad dressing is a liquid under TSA rules — 3.4 oz or less in carry-on, unlimited size in checked bags.

Carry-on details
Allowed with conditions. Because it pours, salad dressing falls under the 3-1-1 liquids rule in carry-on — each bottle must be 3.4 oz (100 mL) or less and fit in your quart-size liquids bag along with your other liquids.
Checked-bag details
Allowed. No size restriction in checked baggage — a full-size bottle of dressing can travel here without issue.
Quantity limit
3.4 oz (per container)
Special instructions
This applies to any pourable dressing, including ranch, vinaigrette, and Caesar. A dressing that's fully solid and frozen is treated like a solid food when frozen and inspectable, but any that has thawed or is only partially frozen is treated as a liquid.

FAQ
- Can I bring a full bottle of ranch dressing in my carry-on?
- Not if it's over 3.4 oz. TSA classifies salad dressing as a liquid under the 3-1-1 rule, so a full-size bottle needs to go in checked baggage instead.
- Does packing a salad with dressing on the side avoid the liquid rule?
- No. Dressing in a separate container is still a liquid and subject to the same 3.4 oz limit in carry-on, regardless of whether it's packed with a salad.
