The 65-year old man, identified by initials Z.N., told a Belgrade court that he had met a Lufthansa flight attendant in Belgrade and wanted to date her.
On Wednesday, having failed to find her in her hotel, he called the Nikola Tesla airport and reported that a bomb had been placed in a Lufthansa plane.
The idea, he said, was to keep her in town, the media reported.The 130 passengers and five crew members had to be evacuated and were forced to wait several hours while a special police unit checked the plane, before it was cleared to leave for Frankfurt.
Police tracked down the culprit after tracing the landline he had used to make the call.
The court ordered the man held in custody for 30 days and he will be charged with causing panic and unrest.
