There is nothing more stressful than starting your highly anticipated vacation by being pulled aside at the airport security checkpoint. Having your carry-on bag ripped open because you packed the wrong size of sunscreen is a frustrating experience that can delay your entire family.
As airports across the United States upgrade their technology and roll out new 3D scanning machines, the security protocols have slightly shifted. Navigating the latest TSA airport rules 2026 is the only way to ensure a smooth, stress-free walk from the ticketing counter to your departure gate.

Navigating the TSA Airport Rules 2026
The most common reason for checkpoint delays continues to be liquids in carry-on baggage. Despite the introduction of advanced new baggage scanners, the federal government has not lifted the famous 3-1-1 liquid mandate for standard screening lanes.
If you are packing shampoo, toothpaste, or expensive perfumes in your carry-on bag, each individual container must still be 3.4 ounces (100 milliliters) or less. All of these small containers must comfortably fit into a single, clear, quart-sized plastic bag. If you bring a full-sized bottle of sunscreen, even if it is only half full, it will be confiscated and thrown in the trash.

The New CT Scanners and Electronics
While the liquid rules remain strict, there is incredibly good news regarding your personal electronics. Airports nationwide have been heavily installing new Computed Tomography (CT) scanners.
According to the updated TSA airport rules 2026, passengers flying domestically through lanes equipped with these new CT machines no longer have to remove their laptops, tablets, or gaming consoles from their bags. The advanced 3D imaging allows security officers to rotate the image of your bag on their screen to clearly see underneath your heavy electronics. However, if you are in an older lane, you will still be required to place large electronics in a separate grey bin.

Food Items That Trigger Alarms
Many travelers are surprised to learn that while you can bring solid food (like sandwiches or granola bars) through security, certain foods will trigger secondary alarms. Items that are spreadable or creamy like peanut butter, hummus, or jam are legally classified as liquids. They are subject to the strict 3.4-ounce limit. When in doubt, it is always safer to pack spreadable foods in your checked luggage.
