Airbus says most of its recalled 6,000 A320 jets are now modified

PARIS — Airbus fleets were returning towards normal operations on Monday after the European planemaker pushed through abrupt software changes faster than expected, as it wrestled with safety headlines long focused on rival Boeing.

Airbus said on Monday that the vast majority of around 6,000 of its A320-family fleet affected by the safety alert had been modified, with fewer than 100 jets still requiring work.
