International Airlines Group (IAG) has posted a strong rise in June traffic, led by a buoyant performance from the British Airways.

The company reported that premium traffic for the month of June 2012 has increased by 5.3 percent compared to the preceding year, while non-premium traffic increased by 9.6 percent in June 2012, from the earlier month.

British Airways’ June traffic was up 11.3 percent compared to a 3.2 percent rise at Iberia.

In June 2012, group traffic measured in Revenue Passenger Kilometres rose by 8.9 per cent versus June 2011 (up 5.9 per cent on a like for like basis); Group capacity measured in Available Seat Kilometres was up 5.8 per cent (up 2.6 per cent on a like for like basis).

Meanwhile, the company revealed that underlying market conditions remain unchanged from last month. “As we had indicated earlier in the year there is likely to be some near-term softness in premium traffic due to the Olympic Games.”
