Unexpected Exceptions To TSA's 311 Liquid Rule

By Nicole Cord-Cruz


The TSA, which oversees the screening of passengers in airports, is notorious for its strict 3-1-1 liquid rule. However, just like most rules, there are quite a few exceptions.
TSA dictates that passengers are required to funnel liquids, gels, aerosols, and spreads into 3.4-ounce containers, all of which should be placed in a transparent bag.
However, any liquid deemed "medically necessary" is exempted from the 3-1-1 liquid rule, including breastmilk, formula, liquid teethers, and baby food in liquid form.
Should you decide to bring breast milk and formula in-flight, the TSA won't raise an eyebrow. You may also bring ice packs and freezer packs to keep the liquid cold.
If your health condition necessitates liquid medication, you may bring it as long as it is in "reasonable quantities" and needs to be consumed mid-air or when you land.
If you have these liquids, notify TSA officers so that they can be declared for further screening. The agency assures passengers that their procedures won't harm their liquids.
