If you fancy a summertime trip to Ireland and you’re already in New York or Boston, Aer Lingus has some great fares from either New York JFK or Boston Logan airport to either Shannon or Dublin starting at just $309 one-way.

The things you’ll need to do in order to get this fare are:

• You have until June 3 (tomorrow!) to book this fare.
• Travel must occur between July 1-31, 2008.
• Travel dates must be Monday, Tuesday, Wednesday or Thursday (a surcharge applies for weekend travel dates).
• This fare includes fuel surcharge of $100, but does not include other charges and taxes.

Other fares from other U.S. cities include $399 one-way from Washington Dulles, $499 one-way from San Francisco, $587 one-way from Orlando, $399 one-way from Chicago, and $499 one-way from Los Angeles. Read more about each deal by clicking on the price listed on the main page of the Aer Lingus website. And if you don’t scoop up one of these low fares by June 3, don’t fret – I’ve seen notes about similarly low-priced Aer Lingus tickets extending out into September and October, so keep an eye out for those, too.
