JOHANNESBURG -- Passengers for Kulula and British Airways have been encouraged to check-in online amid fears of disruptions during a strike at Comair.
Ground staff intend to embark on strike action as of this afternoon.
The company says it has a contingency plan in place, in order to minimise disruptions.
Trade Union UASA issued a 48-hour notice to strike on Monday.
The union represents 60 percent of staff at Comair, who work for both airlines.
UASA is demanding a 10 percent wage hike annually, for three years.
It says the amount is based on inflation data and expected interest rate increases.But Comair is offering only 7.5 percent for the three years.
If the strike goes ahead, it will be a first in the history of Comair – affecting over 400 staff.
Comair is the local franchisee of British Airways which also operates kulula.com.
