Dd has some tablets which need to be kept in the fridge. Pharmacist reckons they'll be fine in a cool bag with an ice pack. But, just in case hold luggage goes missing, can I take a frozen ice pack in hand luggage? It would be as small a one as I can find, so under the 100ml level - I'm sure I've seen really small ones somewhere.
Airport website doesn't say anything about ice packs, so I wondered if anyone knew?
