‘Frozen liquid items are allowed through the checkpoint as long as they are frozen solid when presented for screening,’ the Transport Security Administration (TSA) rules state. However anything ‘partially melted, slushy or with any liquid at the bottom of the container’ isn’t allowed.
Anything less than completely solid means your beverages can still fall foul of stringent 3-1-1 liquids requirements and must be in a container 3.4 oz (100ml) or smaller and be able to fit inside one quart-sized (quarter of a gallon) resealable bag.
So should you want to take a locally brewed coffee with you to stay perky, an immune-boosting homemade smoothie to ward off any in-flight illness, or anything else for that matter, just make sure it’s fully frozen and hasn’t started to thaw. Another useful money-saving tip is to simply bring an empty bottle with you to refill once in the departures lounge.
