Most of us know you can buy 2-3 ounce, empty bottles for your favorite cleanser, conditioner, or lotion for traveling. But you don't want to just toss them in your bags, zip up and go.

Here are 4 quick air travel tips for keeping products in their bottles and out of the rest of your luggage.

1. Don't fill bottles

Leave some headspace in the bottles for expansion and buildup of pressure.

2. Secure pumps

Press pump caps all the way down and twist to lock the pump.

3. Tape caps

Tape caps down with masking tape to keep them from popping open.

4. Label & bag

Finally, label your bottles and put them in zippered plastic bags to prevent leakage and confusion.
