Overall passenger numbers carried by British Airways and Iberia parent company International Airlines Group dropped in July by 2.7% to 5 million from 5.14 million in July 2010.
The decrease was due mainly to a 21.5% drop in passengers on UK and Spain domestic routes.
This was partially offset by a 11.5% rise in the Asia Pacific region and 10.4% growth in the Latin America & Caribbean region.
However, the company saw increased levels of business travel, with July figures showing premium traffic up by more than 14% over the same month last year, with economy up by 2%.
IAG’s capacity on domestic routes was down by more than 22% in the month while more seats were available to Latin America & Caribbean (12%), Asia Pacific (10%) and North America (7.4%). Total seat capacity was up by just under 3%.
