The Airlines Association South Africa has asked for the government to waive fees on aircraft refuelling at alternate airports, to ease pressure on Cape Town.
Mark Mclean, general manager for CPT told the Daily Maverick that the airport had been assigned two million litres of emergency fuel while waiting for the delivery.
"We have a quantity of fuel but it's difficult to say in days," he said.
Passengers booked to travel in and out of CPT over the next week have been told to check with their airlines.
ACSA said that they would be at risk of running dry entirely by midweek if no delivery could be made.
The South African airport relies on imported aviation fuel arriving via ship. Unfortunately weather conditions have delayed the arrival of much-needed fuel by over a week.
"As the port, we are on high alert and tracking the vessel to ensure all resources are ready to receive it when it arrives. The vessel will be receiving berthing priority and we do not foresee any challenges servicing the vessel when it arrives," Rajesh Dana, Cape Town Port manager told CTGN.
