Was passing through DUB Wed. morning about 10.30am and noticed five (5) EI A320's/321? parked remotely near fire station plus 1 x Regional ATR. Two more A320's were "silent" at Pier A. Seems a lot of a/c to be idle at that hour of the day. Was this exceptional or have they "parked" a/c for the winter? (2 x FR738's also parked remote so assume these are 2 of the 80 on the ground).
