Liquid limits on planes: airport restrictions 2026

Navigating liquid restrictions at UK airports can be confusing, especially with recent changes allowing larger containers at some locations. Understanding these rules helps avoid delays and ensures smooth travel through security.

What liquids can you take on planes?

Airport security classifies liquids broadly, including drinks, cosmetics, gels, creams, sprays, and pastes. This covers everything from water bottles and shampoo to toothpaste and hand sanitiser.

Traditional 100ml rule still applies at most UK airports. Each liquid container must hold no more than 100ml, fit in a clear plastic bag (maximum 20cm x 20cm), and be presented separately at security.

2-litre allowance now operates at select airports with advanced CT scanners, including Heathrow, Gatwick, Edinburgh, and Birmingham. These locations permit larger liquid containers to remain in hand luggage during screening.

Which UK airports allow larger liquid containers?

Advanced screening airports using CT technology include:

• Heathrow (all terminals)
• Gatwick (North and South terminals)
• Edinburgh Airport
• Birmingham Airport

Traditional 100ml airports require standard liquid restrictions:

• Manchester Airport
• Stansted Airport
• Luton Airport
• Bristol Airport
• Leeds Bradford Airport (however, you can keep your liquids in your bag - no need to take it out for screening)
• Most regional airports

Which airports globally allow larger liquid containers?

The rollout of CT scanner technology varies significantly worldwide, creating a patchwork of liquid restrictions for international travellers.

European airports with relaxed limits (or partial implementation):

• Munich Airport (Germany)
• Rome Fiumicino (Italy)
• Dublin Airport (Ireland)
• Kraków Balice Airport (Poland)
• Vilnius Airport (Lithuania)

North American airports:

• Most US airports maintain 100ml (3.4oz) limits
• Toronto Pearson (Canada) - testing larger container allowances
• Vancouver International - pilot programmes underway

Asia-Pacific region:

• Singapore Changi - advanced screening technology
• Tokyo Haneda and Narita - traditional restrictions remain
• Sydney Kingsford Smith - gradual CT implementation

Important considerations for international travel:

• Connecting flights may require re-screening under different rules
• Some countries maintain stricter arrival restrictions
• Always verify current policies before departure

The global transition to CT scanners continues, but implementation timelines vary by country and airport funding.

What are the exemptions to liquid limits?

Medical necessities receive special treatment at all UK airports. Prescription medications, insulin, and essential medical liquids can exceed standard limits with proper documentation.

Baby food and formula exemptions apply when travelling with infants. Airlines and security accept reasonable quantities of baby milk, sterilised water, and food. (Keep in mind those might differ between airports and airlines, so always check their specific policies)

Duty-free purchases follow specific rules. Liquids bought after security screening can be carried onboard, but connecting flights may require additional checks.

How to prepare liquids for airport security

For traditional 100ml airports:

• Use containers clearly marked under 100ml
• Pack all liquids in one transparent bag
• Remove the bag for separate screening

For CT scanner airports:

• Larger containers can remain in hand luggage
• Still declare valuable or unusual liquids
• Verify current airport policy before departure

Frequently asked questions about liquid limit on planes

Can I take a full-size water bottle through security?

Only at airports with CT scanners (Heathrow, Gatwick, Edinburgh, Birmingham). Traditional airports require containers under 100ml.

Do liquid limits apply to connecting flights?

Yes, especially when changing terminals or airlines. Rules vary by airport and country.

What happens if I forget about liquids in my bag?

Security will remove prohibited items. You may face additional screening time, potentially causing delays.

Are prescription medications exempt from liquid limits?

Yes, with proper documentation. Carry prescription labels and medical letters for quantities exceeding standard limits.
