Airbus laid out medium-term targets including a near doubling of profits and stronger shareholder returns on Tuesday, signalling confidence in its ability to ramp up production as a bruised aerospace sector turns the corner on supply disruption. The world's largest civil planemaker said it was targeting a core profit of €12 billion to €13 billion ($13.69 billion to $14.83 billion) in 2029, and announced a €5 billion share buyback programme.
