In cabin baggage

Most countries allow expressed breast milk in reasonable quantities. The UK allows up to 2000ml per container. The US allows it without a baby present. Be ready for extra screening.

In checked luggage

Fine in cool packs, but cabin is safer for fresh milk.

Customs caveat: Frozen or refrigerated milk transported across borders may have separate health/customs requirements on long-haul routes. Check the destination's rules.

Separate customs, airline, or import rules may apply. Check official guidance.
