TSA Packing for Last-Minute Flights can be a stressful experience, but knowing the rules can make it easier. When you’re in a rush, it’s crucial to focus on essentials. Keep your carry-on light, adhering to TSA’s 3-1-1 liquid rule: liquids must be in containers of 3.4 ounces or less and placed in a quart-sized bag. Opt for versatile clothing that doesn’t need to be removed during security checks. Electronics should be easily accessible for quick screening. Remember, TSA PreCheck can further simplify the process by allowing you to keep your shoes, belt, and jacket on.
