The number of airline passengers booking flights in Europe in July fell by 2.3 percent compared to the same month last year.
This is according to figures from the Association of European Airlines (AEA), with the rate of decline being largest in the in the north Atlantic region (down by 4.3 per cent).
The far east also suffered a decline of -3.9 percent, while cross-border services within Europe declined by 3.4 percent.
AEA secretary general Ulrich Schulte-Strathaus explained that the premium travel market has been hardest hit by the global financial and economic crises.
"Airlines across Europe are offering great deals to business passengers, but are still not managing to re-energise the market," he commented.
In better news, there was a growth in passenger numbers in both African and Middle Eastern services.
The AEA recently expressed concern over the ongoing trend of airports increasing the fees they charge to airline customers.
