The Authority has also apologised for the inconvenience caused, stating that as of 7:00 am, minimal operations had resumed.
"Meanwhile, we encourage passengers to contact their respective airlines to confirm their flight status."
The statement comes after hundreds of passengers were stranded at the busy airport after several flights were canceled while others experienced delayed.
COTU Secretary General Francis Atwoli is currently meeting with the leadership of the aviation workers union.
Addressing the press earlier at JKIA, Atwoli blamed the government for failing to engage the workers in good time while blaming some state officers for being arrogant.
"The government was in a position to contain this strike way back. They ignored and now we can see the results. We have government officials who are just arrogant and are not ready to listen to the workers," he said.
The aviation workers are protesting the planned takeover of JKIA by Adani Group.
