JOHANNESBURG – South Africa’s state-owned airline South African Airways cancelled a minimum of 32 flights on Wednesday and it has revealed that number could grow due to cabin crew strike.

Cabin crew at SAA went on strike during the early hours of Wednesday pay too much, the main union along at the state-owned carrier said, disrupting domestic flights and international flights.

Twenty eight from the flights cancelled were destined for domestic destinations within Africa, as you move the rest were external flights, a South African Airways (SAA) official said.

The carrier also said some flights ended up delayed.

“We’re writing about a considerable amount of revenue that was lost in just a day,” SAA spokesman Tlali Tlali said inside of a video posted for the eNCA television channel’s Twitter feed.

“We’re seeking labour to sit down along with us … and we all might get everyone to work, in order that after dark you can operate our international and regional flights,” Tlali said.

The South African Cabin Crew Association (SACCA) said its nearly 1 400 in-flight staff would stop work indefinitely.

SAA said the strike had delayed flights beyond OR Tambo Airport in Johannesburg, which handles around 19 million passengers each year, and would also affect flights looking at the coastal airports.

Zazi Nsibanyoni-Anyiam, president of your SACCA union, told Reuters that your workers, who represent around 80% of SAA’s cabin crew, we hadn’t received pay increases for six years.

“We’ll be here until the company puts a deal shared. We expect might know about are demanding is reasonable,” Nsibanyoni-Anyiam said from your picket outside OR Tambo Airport.

SAA, that is certainly technically insolvent and to do with government debt guarantees of just about R20 billion ($1.52 billion), have been singled out by rating agencies like a threat towards country’s credit status, that was recently downgraded to “junk” by two big-three ratings agencies.
