Ireland has thirteen passenger airports. Some of these are small and for regional use only, most serve mainly UK and European destinations. The normal ports of entry for transatlantic travellers will be the following:
Belfast International Airport BFS - scheduled flights to and from New York, Toronto and Vancouver; charter flights to and from Orlando and Toronto.
Dublin Airport DUB - scheduled flights to and from Atlanta, Boston, Chicago, Los Angeles, New York, Newark, Philadelphia and Toronto.
Knock Airport NOC a.k.a. Ireland West Airport - scheduled flights to and from Boston and New York.
Shannon Airport SNN - scheduled flights to and from Boston, Chicago, New York, Newark, Philadelphia and Toronto.
Note that there are a larger number of ways into Ireland if you are prepared to change flights, some of these are cheaper than direct flights - there can even be other huge advantages in this.
