I have put some of the information on Dalaman Airport in one thread, if anyone has any more information please add on
On entry into Dalaman Airport after Visa and Passport control opposite the baggage carousels where you collect your luggage a 24/7 Duty free shop is open for Trade, The maximum allowance for Cigarettes is Three cartons 600 per person, And 2 Litre’s of Spirits you may legally bring into Turkey, At checkout you will be asked to produce your Passport which is scanned at the tills by the staff so that you cannot Purchase anymore.
A word of warning here at Check in should your baggage be overweight at check in you will be charged accordingly by the Airline, See your Airline details for charges, Some Airlines are very strict with this issue.
At Dalaman Airport the same restrictions are now in place as any other European Airport, At the first security check in at the front doors you can take liquids through, You then check in your luggage etc, walk to the centre of the Airport and you come to the security check where all liquids are taken from you, You then go through passport control and then come through into the departure lounge.
The Airport has many shops/Bars Cafe's Duty free goods etc, Note all of these shops are very expensive to purchase food and drinks from, Take sandwiches crisps peanuts etc from the Resort your actually in as they will be far less expensive than Airport shop prices.
