Aer Lingus lost €9.9 million in the first half of the year, which is a fall of nearly 40 per cent on the losses experienced in the same period last year.
The airline also had to contend with industrial action in the first six months, which is estimated to have cost the airline €10 million. The airline said that "this first half operating result would heave approached break-even in the absence of strike action in the first six months of 2014."
In the first half of the year there was an increase in overall passenger volume by 1 per cent to 4.615 million. Revenues were also up, increasing by 6 per cent to €697.2 million.
Chief executive officer Christoph Mueller said, "our long-haul business is performing very well. It's not necessarily to and from Ireland only; we now reach out to the UK and to continental Europe.
"50 per cent of our long-haul passengers are either transferring in the United States or in Dublin towards Europe, and that is a big success story."
Recent trends led Aer Lingus to lift its profit guidance, which it had downgraded in June after the industrial action. The airline now says that full year operating profit is expected to around the same as in 2013; approximately €61.1 million.
