Carry-on liquids, medicine and food

Understand container rules, medical-liquid screening and why destination customs can give a different answer from airport security.

The short answer

Container size controls ordinary cabin-liquid screening; medically necessary liquids and baby supplies can have a different procedure. Food can also face a separate destination customs check.

What changes the answer

  • Container capacity rather than remaining amount
  • Medical or baby-use exception procedures
  • Departure security and destination customs rules
