🥣 Soup

A thermos or container of liquid soup over 100ml will be confiscated at the checkpoint, as TSA and equivalent agencies classify liquid soup the same as any other liquid. Officers will not make an exception based on temperature or the fact that it's food. If you want soup for the journey, buy it after clearing security or bring powdered soup to dissolve once you're through.

Liquid soup is classified as a liquid in the US, UK, EU, Canada, Australia, and virtually every other major aviation system, so the 100ml limit applies everywhere in carry-on. Instant or powdered soup, however, is a solid and passes through with no restrictions globally — the classification consistently depends on whether the soup is in liquid form at the time of screening.

All liquid soup — whether smooth broth, blended, or chunky with solid pieces — is treated as a liquid at the checkpoint. The presence of solid ingredients in a liquid soup does not change the classification; if it pours, it's a liquid. Only soup that is entirely solid or dry, like a sealed packet of instant powder, escapes the liquid rule.

The easiest approach is to pack instant powdered soup sachets in your carry-on — they have no restrictions and you can make them with hot water from the flight attendant or at a café past security. If you want ready-made liquid soup, look for options in the food outlets beyond the security checkpoint at your departure airport.
