Scotland's airport managers have issued a joint appeal for passengers to prepare for new rules on carrying liquids on flights.
The new rules for passengers start on Monday
The ban on taking drinks and toiletries through security checks in UK and EU airports is to be relaxed from Monday.
Travellers will be limited to 100ml per container and no more containers than would fit in a one-litre plastic bag.
Airport operators have warned the changes are not a return to normal and are advising people to arrive prepared.
BAA Scotland, owner of Glasgow, Edinburgh and Aberdeen Airports, has joined forces with Highlands and Islands Airports Ltd (HIAL), Infratil Airports Europe, which operates Glasgow Prestwick Airport, and Dundee City Council, operators of Dundee Airport, to ensure passengers comply with new security restrictions.
They are telling travellers to "arrive early and arrive prepared".
More than 500,000 clear plastic bags will be distributed to passengers over the next few weeks.
Extra staff will also be drafted in to help and leaflets and posters will be distributed throughout the terminals.
BAA Scotland spokesman Malcolm Robertson said: "Despite the relaxation of certain security restrictions, this is not a return to normal and we will be drafting in extra staff to ensure the transition to the new security system is a smooth and safe process.
"It is important that passengers play their part by arriving at the airport early, and fully prepared."
The curbs on carrying liquids came in August after police said they had foiled a plot to bring down as many as 10 planes travelling from the UK to the US.

Verified prescription medicines essential for flight
Baby milk and liquid baby food
The new rules mean essential medicines and baby food are allowed in amounts larger than 100ml.
Large musical instruments are also permitted, in addition to one item of cabin baggage.
Security experts believe explosives disguised as a liquid would not be able to destroy an airliner if carried in small 100ml quantities.
To help combat waiting times, people checking in luggage are encouraged to pack any liquids in their suitcase.
Mark Rodwell, chief executive of Glasgow Prestwick Airport, said: "Passenger preparation is the key to the airport's ability to provide fast and efficient security screening and we would encourage all passengers to take the time to pack correctly before arriving at the airport."
