What size toiletry bag for carry-on?

TSA requires liquids in a quart-size clear bag. Your toiletry bag can be any size, but keep it under 10 x 7 inches to fit in a carry-on. The Gonex Dopp Kit is the most carry-on friendly.

How to prevent leaks during flights?

Squeeze air out of bottles before sealing. Use silicone travel bottles with locking caps. Place them in a bag with waterproof lining. Cabin pressure changes are the main cause of leaks.
