Quart Size Bag Vs Sandwich Bag

The TSA has specific guidelines for what size and types of liquids can be carried on an airplane. All liquids must be in containers that hold 3.4 ounces (100 milliliters) or less per item. These containers must be placed in a single, clear, quart-sized bag. Only one item per bag is allowed. The bag may be placed in a carry-on bag or in your checked bag.
