Icelandic carrier WOW Air plans to start selling flights from Dublin to the US from as little as €149.
The low-cost airline will start flying from here to Boston and Washington DC in October.
The €149 fare includes taxes, but passengers will have a two-hour layover in Reykjavik.
The airline, founded and headed by Skuli Mogensen (above), previously announced that it will start flying between Dublin and Iceland's capital this June.
The launch of a transatlantic service comes as the airline plots a strategy to be one of the first "true low-cost" airlines operating between Europe and the US.
It is also launching flights to Boston in March from London Gatwick airport and will service Washington DC from Gatwick from June.
