Brits heading on holidays need to navigate hand luggage rules, and we're not just talking about airlines' allowances including TUI, easyJet and Jet2.
There are plenty of items banned from hand luggage, but one of the biggest rules is that all liquids need to be under 100ml.
But what if you're travelling with a baby and need to bring milk and food on board?
The good news for parents is that baby food and milk are not subject to the same restrictions.
In fact, the 100ml doesn't apply for breast milk, formula or soya milk which you are bringing for your baby.
According to the Home Office website: "When travelling with a baby you’re allowed to take enough baby food, baby milk and sterilised water for the journey. There is no legal limit to how much you can take however check with your airport before you travel.
"You can carry breast milk in hand luggage even if you’re not travelling with a baby. You cannot carry frozen breast milk in hand luggage.
"Individual containers of breast milk must hold no more than 2,000ml. Each container will need to be screened at the security point. Airport staff might need to open the containers to screen the liquids."
We take a look at the rules on baby milk and food when you're flying.
Baby milk
Baby milk is not subject to the 100ml restrictions.
You can bring individual containers with up to 2,000ml of breast milk in your hand luggage, and your hold luggage.
Formula milk, sterilised water and soya milk are allowed in your hand luggage but only if your baby is travelling with you at the time, otherwise you won't be able to bring these on board.
Breast milk however can be brought on board even if you are not travelling with your baby.
It's worth noting that you won't be allowed to bring frozen breast milk with you in your hand luggage, although you are allowed to store this in your hold luggage.
All other liquids you bring will be subject to the usual 100ml restrictions.
Baby food
Baby food is not subject to the 100ml rules.
You can bring baby food with you in both hand luggage and hold luggage, even if you are not travelling with your baby at the time. (The same rules apply to breast milk and cooling gel packs).
