The number of passengers flying with Aer Lingus in June was up by more than 10% on the same period last year.
The national airline carried 852,000 passengers in June, an increase of just over 10% on the same month last year.
But its load factor, the percentage of seats filled, fell back 1.2 points to 80.1%.
Chief executive Dermot Mannion described the performance as 'robust'. The company increased its short-haul capacity through the introduction of three new planes and bought an extra long-haul plane last month.
For the first half of 2007, passenger numbers were up 5.9% to just under 4.4 million, while the load factor fell 1.8 points to 75.3%.
Long-haul passenger numbers in June grew by 14.7%, while short-haul numbers were up 9.4%. Load factors fell by 1.4 points and one point respectively.
For the six months, long-haul passengers rose by 2.3% and short-haul by 6.5%. The long-haul load factor was down 1.3 points, short-haul down two points.
