Refers to terminal 2. Building is spacious no real complaints about departing. Problems however arise on arrival into terminal 2. We arrived from Amsterdam taxied to the gate and exited the planet he walk from the plane to the immigration area took 12 minutes we had to go upstairs downstairs along corridors one of which had a travelator (not working) - when we finally got to the immigration area the exit was closed. No one thought to open the shutter and we were left waiting there in a corridor like herded sheep with no air con and no windows - after a 10 minute wait some passengers became enraged and started to pound on the shutter this had the desired effect and after a 5 minute pounding the shutter was eventually opened. At least 3 employees of DAA who were asked for an explanation just shrugged their shoulders and said it "wasn't their fault". Thankfully the process through immigration and customs was fairly swift. However when we exited terminal 2 and had to walk half a mile to terminal 1 to get the bus back to the car park. DAA have let Ireland down with this very poor service. I for one will never travel through terminal 2 again.
