Following the technical issue it encountered yesterday, British Airways A319 G-EUPT positioned Cagliari – Marseille this morning as BA9252 and then continued Marseille – London Heathrow at 24,000 ft with landing gear down but diverted instead to Paris CDG. The aircraft then continued Paris CDG – London Heathrow again at a maximum of 24,000 ft with landing gear down after around an hour on the ground.
