The new terminal at Dublin airport will open on a phased basis on November 19th.
Dublin Airport Authority (DAA) said airlines will begin to transfer their services to the second terminal from November 23rd.
Aer Lingus, Etihad Airways and a number of US carriers are planning to use Terminal 2. During the transition period, which will extend into early December, Aer Lingus will operate from both terminals. Intending passengers will be informed which terminal to use.
Aer Lingus says its London services will use Terminal 2 from November 23rd; other short-haul services will use the terminal from November 30th.
Meanwhile, transatlantic services operated by Aer Lingus, Delta, Continental Airlines and US Airways will operate from Terminal 2 on December 7th.
American Airlines will begin operating from T2 when it resumes its Irish services next year.
The US Customs and Border Protection system will begin operations at Dublin airport early in the New Year, although a start date has not yet been agreed with US state agencies.
“It has always been our intention to open Terminal 2 on a phased basis and we have been working closely with our airline customers, ground handlers and the various State agencies in recent months to ensure a smooth transition,” DAA chief executive Declan Collier said.
