London Luton to Dublin liquid rules
LTN → DUB · United Kingdom → Ireland
100ml out, larger allowed back. Pack to 100ml for the outbound departure. The return airport's guidance allows larger containers for ordinary departures — check its exceptions.
Rule basis: Both airports have official guidance we can show (see each airport's source and check status).
What to do: Conservative packing fallback: containers of 100ml or less, all in one clear resealable bag of up to 1 litre, ready to take out at security. Exceptions: DUB: Dublin's 2-litre allowance is per container (no limit on the number of containers) and also applies at its connecting and self-transfer security checks. DUB: US preclearance at Dublin adds US immigration, customs and agriculture checks; Dublin's pages don't state a liquids allowance for any extra US screening — confirm with your airline and pack to 100ml if unsure.
Liquid Limits is a travel planning tool, not an official aviation source. Always confirm with the airport before you travel.

What to pack in cabin baggage
Conservative packing fallback: containers of 100ml or less, all in one clear resealable bag of up to 1 litre, ready to take out at security. This works at both LTN and DUB, including any exceptions listed above. Keep medications and contact lens solution accessible — they can usually go above the limit.
What to check in hold luggage
Full-size shampoo, perfume, sunscreen, olive oil, jam — anything over the limit. Wrap glass in clothes and seal liquids in plastic bags in case pressure changes pop the lids.
