"The first take-offs and landings have resumed. However, there will still be cancellations and significant flight delays today," the airport said on X.
Hamburg's international airport was closed to all arriving and departing flights on Saturday night after a gunman rammed a security barrier onto the airport tarmac and parked under a plane. The man was holding his four-year old daughter hostage.
On Sunday, after lengthy negotiations, he released the child and surrendered to the police.
