I travel to heathrow twice a week at the moment with EI/BD and all I can say is that this is going to add to my frustrations of using Dublin Airport.
When I worked on the ground for EI we still had Area 9 down in the arrivals level which had its own problems such as a totally insufficient baggage system, freezing cold temperatures as a result of the doors out to the bus area, a single small narrow lift from Area 9 (beyond O'Briens) to the main departures area and a bloody long walk if you were departing from Pier B or C upstairs to security. Now it seems that things are just going full circle.
The last thing a passenger wants when they lug their baggage out of a car and onto a trolley is to fight through the crowds to get to a lift and descend three floors, they want the checkin desks to be just the other side of the entrance!
Oh well, dont we just love EI and the DAA!!!
