How do you pack powdered formula on a plane?

Make enough bottles to last 50 percent longer than you think you'll need and tuck them into a soft-sided cooler bag with frozen ice packs. If you prefer to make fresh formula on the plane, measure powdered formula into each bottle and screw the lid on tightly. Disposable bottles and liners are convenient.

The TSA classifies baby formula as medically necessary, so you can pack as much baby formula as you need for the trip without being limited to the 3.4-ounce rule that applies to other liquids. When you go through security screening, inform airport security of the amount of baby formula you're carrying.

If it's a short trip, pack your prepared formula in a cooler or insulated bag with lots of ice packs. This can be done with prepared powdered, concentrate, or ready-to-feed formulas. Prepared formula can be stored within a cooler bag with ice packs for as long as the temperature inside remains cold enough.
