IAG shares shot higher on Thursday after the Iberia and British Airways owner said it now expects to report a third-quarter operating profit of around €1.2bn after stronger-than-expected trading.
In a brief and unscheduled update, the company said trading in the third quarter was boosted by passenger revenue strength.
“Forward bookings remain at expected levels for the time of year, with no indication of weakness, and accordingly our fourth quarter expectations remain unchanged as of today,” it said.
IAG is due to announce its results for the nine months to the end of September on 28 October.
At 1325 BST, the shares were up 8.9% at 109.72p.
