On the last Sunday we could smoke on a special place in front of the check-in at the Heraklion-Airport but smoking in the departure lounge (after the security check) was not allowed.

I can confirm it wasn't allowed in the airside lounge in May. However, it was allowed (at least it was happening) upstairs in the corridor leading to the misnamed Duty Free shop and you could cut the atmosphere there with a knife. Most unpleasant.
As for Plakias, no change I think. Smoking is still allowed in the tavernas irrespective of how enclosed they are (in the UK the ban applies in enclosed and semi enclosed areas, the latter including bus shelters). From my perspective the UK ban is just the sign of a more civilised society.
In my experience the chances finding a Greek man who doesn't smoke are similar to finding rocking-horse droppings.
