Re: US Immigration queues at Dublin, get there early!!
When I arrived back in DUB this Saturday, we came into the (old) new bit of the terminal - the well designed straight bit to the left after you come through security. This bit is due to be knocked down as part of the next round of redevelopment at the airport from what I've heard. Go figure . . .
Anyway, this is also the bit that doesn't have US pre-clearance.
When we arrived there were AA, Delta and Continental planes there - so unless the passengers were bussed over from the pre-clearance area (possible, but I haven't seen it before) then all the passengers on those flights would have had to clear immigration at their destination instead of Dublin.
Maybe the airlines have got tired of having their passengers coralled in that awful squishy little area (with insufficient seating, one tiny coffee shop and no way out) after you pre-clear immigration.
