* Supply disruptions from Iran war have hit airlines hard
* IAG says profit, cash flow and capacity will be lower than guided
* CEO says 70% of 2026 fuel needs hedged
* Shares plunge by 5% (Updates with shares, comments from media call)
May 8 (Reuters) - British Airways owner IAG's annual profit will be lower than forecast, it warned on Friday, saying that soaring jet fuel costs and supply disruptions driven by the Iran war will weigh more heavily on earnings than previously expected.
IAG Shares were down more than 5% when markets opened, making it one of the biggest losers on the FTSE 100.
The company said that free cash flow and capacity would be lower than previously projected, joining Air France-KLM , easyJet and others in flagging a hit tied to spiralling fuel costs.
IAG, which also owns Iberia and Aer Lingus, expects jet fuel costs to be about 9 billion euros ($10.56 billion) this year, with 70% of its anticipated fuel needs hedged for the remainder of 2026.
“We are actively managing the uncertainty created by the fuel price increase and its impact, taking the necessary action on yields, costs and capacity. We currently see no issues with fuel availability in our main markets," Chief Executive Luis Gallego said in a statement.
He added on a media call that the company expects this year's jet fuel costs to be about 2 billion euros higher than in 2025. IAG had previously said its airlines would have to charge higher fares to offset the rising cost of fuel.
The company did not give specific projections for annual profit on Friday but said that "capacity will be lower than the 3% increase guided at full-year results".
Free cash flow would also be lower than the previously projected 3 billion euros, its statement said. IAG beat profit expectations when it reported full-year results in February, but its shares dropped on uncertainty over its 2026 guidance.
