I have just checked the flying rules in relation to liquids and this is what BA say:
Carriage of Liquids in hand baggage
Summary
What are the rules regarding the carriage of liquids on a flight?
More information
European Union Liquid Policy
The EU rules on liquids apply to all air passengers travelling from any EU airport, including UK airports, as well those travelling from Albania, Kosovo, Iceland, Norway and Switzerland regardless of their destination. The changes became effective from November 6, 2006.
Limited quantities of liquids, gels or pastes must be held in individual containers not exceeding 100ml (approximately 3.5 fl. oz).
This may include:
· Shampoo
· Creams
· Hair gel, hair spay
· Suntan lotions
· Toothpaste
· Liquid or aerosol deodorants
· Perfumes
· Cosmetics such as mascara and lip gloss
· Water and other drinks, soups and syrups
· Other items of similar consistency
The containers must be carried in a separate clear plastic, zip-top or re-sealable bag that does not exceed 20 cm x 20cm (8 inches x 8 inches) or equivalent to one litre capacity.
Items must fit in the bag comfortably and the bag must be completely closed.
At the airport security search, the plastic bag must be removed from the cabin bag and x-ray screened separately.
Which countries are in the EU?
Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece,
Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Poland, Portugal, Rumania, Slovakia, Slovenia, Spain, Sweden, The Netherlands, and the United Kingdom
In addition, air passengers travelling from airports in Albania, Kosovo, Iceland, Norway and Switzerland should comply with the new liquids policy.
Why does the new policy affect all EU countries and Albania, Kosovo, Iceland, Norway and Switzerland?
The European Union agreed a new policy that brings into line all EU countries. Some non-EU countries such as Albania, Kosovo, Iceland, Norway and Switzerland have also agreed to implement the same policy.
The change in policy protects air travellers against the current security threat.
Greater consistency will help customers understand more easily what they can and can't take onboard flights with them in the future.
Liquid Policy from USA and Canada
The Transportation Security Administration in the USA and the Canadian Air Transport Security Authority relaxed the restrictions in September 2006 on the carriage of liquids through airport security searches on flights departing airports in the USA and Canada.
Customers may take with them in their cabin bag limited quantities of liquids, gels and aerosols, including travel-size toiletries such as shampoo, suntan lotion, creams, toothpaste, hair gel and hair spray.
Containers holding liquids must not exceed three American ounces or 90ml.
Liquid containers must be carried in a separate clear plastic zip-top bag that does not exceed 20 cm x 20 cm or 8 inches x 8 inches or quart size.
Items must fit in the bag comfortably and the bag must be completely closed.
At the security search, the plastic bag must be removed from the cabin bag and x-ray screened separately.
Customers carrying liquids may be subject to secondary searches before boarding.
