About 170 passengers, who had been walking about 100 metres from the airport terminal to the aircraft were unhappy about having to wait in the sun while the passenger was loaded.
Some passengers gave up and breached an order to wait at the foot of the stairway and walked up to the aircraft door.
They were spotted talking to the General Manager of the Airport Terminal Service (ATS), Paul Karalus.
Some passengers were overheard complaining that the staff at the terminal should have made sure there was no issue before releasing them to walk to the aircraft.
