Airports Company South Africa (ACSA) has prohibited Air Zimbabwe from using its airports over a non-payment of charges.
The company did not disclose the outstanding fees to maintain client confidentiality.
Air Zimbabwe, which is a cash client, is required to pay its dues each Monday. The charges include landing fees, parking fees and weekly flight passenger service charges, as well as any other arrears it may incur.
ACSA stated that the airline did not comply with the terms to use the airports.
Air Zimbabwe was reportedly informed by a letter on 18 October that its flights are now prohibited from departing from any of the airports.
The ban will be valid until the airline settles its outstanding dues.
ACSA stated that the revised regulations were published on 15 December 2017 in the Government Gazette Notice 968, paragraph 2, which details the payment of charges for landing, taking off and aircraft parking.
ACSA owns and operates a total of nine airports in the country, including Cape Town International and O R Tambo International in Johannesburg.
In April, Cape Town International Airport (CTIA) decided to invest around R7bn ($499m) to implement various infrastructure projects over the next five years.
As part of the project, CTIA planned to upgrade its domestic arrivals terminal and expand the international terminal.
In February, OR Tambo International Airport unveiled phase one of the R4.5bn ($324m) mixed-use development project.
The project includes the construction of new cargo facilities, offices and upgrades to the airport’s façade.
In February last year, ACSA announced that boarding calls for domestic and international departures will not be made from March 2018 throughout Cape Town International Airport.
Only limited boarding announcements will be made at the international departure boarding gates.
