AER Lingus said its performance during the key summer months of July and August of this year was better than the same time last year.
The airline said yields per passenger for July and August increased by 4.6pc compared to last year.
It said that passenger volumes for July and August rose by 1.4pc, and passenger yields are 7.1pc ahead so far this year.
Aer Lingus said that ancillary revenue per passenger increased by 5.1pc compared to the same time in 2010 and is now in line with 2010 on a year-to-date basis.
"This revenue performance, combined with the ongoing benefits of the Greenfield cost reduction programme, meant that Aer Lingus traded ahead of the prior year in July and August," the trading statement said.
