DUB continues to be a traveler's nightmare. Departing from D pier is a particularly horrible experience because of the very long walk. We made the mistake of eating Burger King at the new Terminal 1 Extension – it was so slow we gave up after 15 minutes although at no time were more than 3 people in front of us! The extension itself is very nice although the whole airport smells of one big toilet - I think it is the 'cleaning product' that is used/sprayed in the toilets. Please DAA do something about this (and the other 100 or so problems with your airport).
