For domestic flights within most countries, the general rule is that you can carry liquids in containers of up to 100ml each in your hand luggage, and all such containers must fit into a single transparent, resealable plastic bag with a capacity of no more than 1 litre. However, for many domestic flights within countries like Australia, there are no restrictions on the amount of liquids you can carry in your carry-on luggage, though aerosols must have a lid. Also, in some airports with advanced security scanners (like certain UK airports), liquid limits might be relaxed to allow containers up to 2 litres without needing to remove them during security checks. It is important to check the specific airport rules for your departure and arrival locations. Summary:
- Standard rule for most airports: liquids in containers no larger than 100ml, all fitting in one transparent 1-litre resealable bag.
- Some airports allow up to 2 litres per container with no bag requirement.
- Domestic Australian flights have no liquid quantity restrictions for carry-on, only aerosols require lids.
- Always verify the specific airport's rules before flying.
This applies specifically to hand luggage or carry-on luggage. For checked luggage, restrictions on liquids are generally more relaxed but depend on airline and country regulations.
