Dublin airport's Terminal 2 was officially opened this morning.
The first official flight arrived today, but airlines that are using the new terminal will begin transferring their services to the facility from next Tuesday. It will not become fully operational until the New Year.
Aer Lingus has advised all departing passengers and people collecting arriving passengers to report to Terminal 1 until further notice.
The transfer of transatlantic flights to Terminal 2 has been delayed as the US customs and border protection service will not be operational there until January.
The new terminal has been built at a cost of over €600m and has capacity for up to 15 million passengers.
Terminal 2 will be home to Aer Lingus, American Airlines, Continental Airlines, Delta Air Lines, Etihad Airways and US Airways.
Aer Lingus has already started putting selected flights through Terminal 2. It expects to operate a range of flights into and out of the new terminal over the coming weeks, as it prepares for the full transfer of its scheduled operations from January.
Etihad Airways will operate its first full scheduled service from Tuesday, November 23, when it transfers its Dublin operation to Terminal 2. The terminal will open to the public on November 23 to coincide with the Etihad move.
The new terminal contains almost 40 new shops and food and beverage outlets. The overall T2 construction project includes a new terminal building, a new boarding gate pier, a new heat and power facility, 19 new aircraft parking stands and an upgraded airport road network.
Ryanair has criticised the project as a white elephant, saying it is not needed, and has called for it to be mothballed.
