What are the latest TSA liquid rules for 2026?

The 3-1-1 rule still applies in 2026: liquids must be in containers of 3.4oz (100ml) or less, all fitting into one quart-sized clear bag. However, many major US airports with new CT scanners now allow you to keep liquids inside your bag during screening.

Are packing cubes worth it for international travel?

Yes, packing cubes are essential for organization and space-saving. They allow you to categorize your clothes and compress them by up to 30%, making it easier to travel with just a carry-on bag.

How do I avoid overweight baggage fees in the USA?

To avoid fees on US airlines like Frontier or Spirit, use a lightweight travel backpack that fits under the seat as your personal item. Always weigh your bag at home and wear your heaviest jacket and shoes during transit.

Is rolling clothes better than folding for saving space?

Rolling is generally better for saving space and preventing deep wrinkles in synthetic and cotton fabrics. For formal wear, a 'bundle wrap' technique is often preferred to keep items flat.
