The parent company of British Airways and Aer Lingus, IAG, has said it will slow its growth plans following the terrorist attacks in Brussels in March.

IAG, which also owns Vueling and Spanish airline Iberia, is planning to expand the number of routes it flies to. But with fewer high-margin business flyers since the attacks on Brussels airport and metro line, IAG said it will add those new routes at a slower pace.

It comes as the BA owner ported a pre-tax profit of €124 million (£96m) in the first quarter of the year, compared with a €37m in the same period last year.

Shares fell more than 3.5% on the news of slower growth plans, despite the return to profit.

Operating profits, were €155m before one-off exceptional charges, up from just €25m last year.

IAG chief executive Willie Walsh said: "March revenue was affected by the timing of Easter and Brussels terrorist attacks.

"Revenue trends in quarter two have been affected by the aftermath of the Brussels terrorist attacks, as well as some softness in underlying premium demand. As a result, IAG has moderated its short-term capacity growth plans."
