Munich airport said early on Friday that drone sightings on Thursday evening had forced air traffic control to halt operations.
What has been the disruption to Munich airport?
This had prompted the cancellation of 17 flights, disrupting travel for nearly 3,000 passengers at the airport in the southern German state of Bavaria.
Another 15 arriving flights were diverted to Stuttgart, Nuremberg, Vienna and Frankfurt, the airport said in a statement.
German police said the airport's runways were closed late in the evening as a precaution.
Police officers searched the area for suspicious individuals but found nothing. A police helicopter was also deployed.
Reuters reported that the airport was reopened later on Friday morning.
Denmark and Norway airport closures
The development comes after sightings temporarily shut airports in Denmark and Norway last week.
The incident comes as Germany's Oktoberfest, which draws hundreds of thousands of people every day to Munich, is approaching its final weekend.
