The common travel size limit for liquids in carry-on luggage is generally 100 milliliters (about 3.4 ounces) per container. These containers must usually fit inside a single transparent, resealable plastic bag with a total capacity of no more than 1 liter. This is known as the 3-1-1 liquids rule and applies at most airports globally, including in the US and Europe. However, some airports like Edinburgh and Birmingham in the UK have relaxed this rule, allowing containers of up to 2 liters each in carry-on luggage without the need for a plastic bag or removing liquids at security. The 100ml rule remains the standard at most other airports. To summarize:
- Standard travel size for liquids: 100ml (3.4 oz) per container
- Containers must fit inside a 1-liter clear plastic bag (except in some airports)
- Some airports allow up to 2 liters per container (e.g., Edinburgh and Birmingham)
- Liquids include drinks, toiletries, creams, gels, pastes, aerosols, and similar substances
Always check the specific airport rules before traveling as regulations may vary.
