Earlier today I posted a deal for direct Aer Lingus flights from Shannon to Boston for €277 return and now here is a full list of Aer Lingus sale fares from Dublin or Shannon to North America starting from €277 return!
There are plenty of destinations with direct flights from Dublin or Shannon to New York, Boston, Toronto, Hartford, Washington, Philadelphia, Miami, Los Angeles, San Francisco, Minneapolis, Chicago and Seattle.
Prices start from €277 return and are hand luggage only fares. You can upgrade from a Saver fare to a Smart fare, which includes a checked bag, from €40 one way.
The period of travel for these deals are between 1st Nov – 31st Mar with the busy Christmas period being the blackout dates. There is no time period of when this promotion ends (from what I can see anyway!) so book early to avoid disappointment.
