International Airlines Group (IAG), the parent company of British Airways, has reported a significant financial impact from rising fuel prices and a major air traffic control outage. The September 8 incident disrupted 500 flights and affected 85,000 customers, costing IAG between €25m and €30m (£20.5m to £24.6m) in the third quarter.

The airline group also faced a 30.4% increase in jet fuel costs, adding €570m (£471.9m) to its expenses for the quarter. This has led to a 12.9% drop in pre-tax profits to €1.63bn (£1.33bn).

IAG expects full-year fuel costs to reach €8.9bn (£7.28bn), despite efforts to manage fuel prices in advance. The company is working to recover most of the increased fuel costs through higher fares, but it has not disclosed the extent of fare increases.

Bomb threats triggered flight diversions and emergency inspections across Europe this week. The Cyber Monitoring Centre estimated that the September outage cost the UK economy £33m.

More than 2,000 flights were cancelled across the sector during the disruption. IAG has also dealt with ongoing disruptions from bomb threats, which have caused flight diversions and emergency inspections across Europe.
