What's Dublin DUB airport like?
Its a big flat area with lots of grass, a few runways and taxiways, a terminal building, and airplanes take off and land there.
Sorry, seriously, it is a great airport for pics provided that you are prepared to get out of the terminals and go down the side of the runway - its quite a walk and a rental car might be the best option. Lots of Aer Lingus (no surprise there then) and Ryanair (though very few 737-800s), and a pretty good mix of other traffic too. I like DUB!
