Dublin Airport has direct flights to over 150 destinations. In general, flights can be booked up to 350 days in advance. For most carriers, the earlier you book, the better the deal.

Some carriers, including the Irish national carrier, Aer Lingus, frequently have sales. The best deals can usually be found by signing up to the e-newsletters of your chosen carrier. For those travelling from North America, a discounted fare structure has been negotiated with Continental Airlines.
