- IAG's chief executive warned that scarce sustainable aviation fuel could leave European airlines at a cost disadvantage.
- Proposed environmental charges may raise fares as the group absorbs higher fuel costs.
- IAG's nine-month pre-tax profit fell 16 percent to 3 billion euros through September.
International Airlines Group faces a fresh cost concern after chief executive Luis Gallego warned on Monday, November 9, that planned environmental charges and limited sustainable aviation fuel could weaken European airlines. City AM reported that Gallego expects the measures to raise passenger fares and widen the cost gap with global competitors.
IAG stock traded at 5.45 euros on Lang & Schwarz at 18:03 CET on Tuesday, November 10, 2026.
Fuel supply meets tougher rules
British airlines currently face a requirement for sustainable aviation fuel to make up 3.7 percent of their fuel mix. City AM reported that the share is due to rise to 10 percent by the end of the decade, while Gallego said producers are not supplying enough SAF to meet the proposed targets.
The chief executive called for a level playing field, arguing that European airlines could face a major cost disadvantage if regulation advances faster than fuel production. For investors, the issue adds a structural cost question to the near-term impact of higher conventional jet-fuel prices.
Profit already under pressure
The warning follows a weaker third quarter and a difficult nine-month period. City AM reported that IAG's pre-tax profit fell 16 percent to 3 billion euros in the nine months through September, with the group attributing the decline to a significant increase in jet-fuel prices from March onward.
The immediate investment focus is whether stronger travel demand can offset fuel inflation, environmental compliance costs and potential fare pressure. Management's comments on capacity, pricing and fuel procurement will remain important as the group moves through the next reporting cycle.
