Why are Aer Lingus operating A330s transatlantic from the low cost pier when there are airbridge stands available on the main pier?
They use Pier D for unloading aircraft when they arrive in from the US. They use airbridge stands (Pier B) for departures as all their flights go through the US pre-clearance facility. Atleast T2 will offer enough capacity to unload and reload the A330s at the same gate rather than shuffling them around the airport.
