A strike by employees of the Israel Airports Authority shut Ben Gurion International Airport for four hours on Tuesday morning, an authority spokeswoman said.
The workers, who are seeking a wage increase, walked off the job between 0600 GMT and 1000 GMT.
The spokeswoman said the strike could be extended depending on the results of talks between management and employees on Tuesday.
"It is possible (it might continue), we have to see what happens," the spokeswoman said.
She added that all airlines had been warned in advance and had either postponed flights or moved them forward.
