Operations resumed at Munich Airport on Saturday morning after drone sightings forced overnight flight suspensions, though travelers were warned to expect ongoing delays.

"Capacity is now gradually being ramped up again," an airport spokesman said. He advised passengers to check the status of their flight with the relevant airlines before travelling to the airport.

Air traffic at Germany's second-largest airport was suspended for the second night in a row on Friday evening as a precautionary measure after drones were spotted.

Police reported two drone sightings in the area of the northern and southern runways shortly before 11 pm (2100 GMT) on Friday. "The drones immediately flew away before they could be identified," a spokesman said.

The airport said 46 flights were unable to depart, while 23 arriving flights were diverted and 12 flights to Munich were cancelled, affecting about 6,500 passengers.
