Organize your liquids with the traveler’s best friend: resealable plastic bags

TSA regulations change regularly, but at this writing, small (no larger than 3-ounce) bottles containing liquids such as contact-lens solution, hand cream, mouthwash, and the like are allowed on most flights. You must, however, place all such containers in a clear 1-quart resealable plastic bag that you must remove from your carry-on before everything goes down the conveyor belt. Organize liquids before you reach the airport: fussing with toiletries on the security line causes delays and invites much ire from security personnel and fellow travelers. Note that liquids such as baby formula and prescription medications are allowed in reasonable amounts exceeding 3 ounces, but you must declare them as you go through security and be prepared for them to be inspected.
