South Africans making their annual trip home from abroad were surprised to land at OR Tambo International Airport on Friday morning to find out connecting flights to their respective hometowns were cancelled."They approached me and told me that my flight had been cancelled and that they will try and transfer me to a different flight. "They didn't really give us a guarantee that we are going to get flights but they said that if they have a space they will have to transfer us but if there is no space then they don't know what to do," a visibly distressed Ncebakazi Ntoni, 26, told News24 on Friday.Earlier on Friday, SAA spokesperson Tlali told the media it would continue to ground flights until Monday after initially cancelling all domestic, regional and international flights for Friday and Saturday due to two unions embarking on industrial action.#SAA Spokesperson Tlali Tlali has arrived to brief us on the latest @TeamNews24 . pic.twitter.com/KIsBXr3cra— Canny Maphanga (@CannyMaphanga) November 15, 2019"The cancellation of regional and domestic flights will be extended to Monday but we have decided to continue with international flights on Sunday," Tlali said.The National Union of Metalworkers of SA and SA Cabin Crew Association announced earlier this week they were embarking on a strike from 04:00 on Friday.The two unions, representing more than 3 000 SAA staff members, said the strike was to protest plans to fire 944 employees, and the carrier's failure to meet their pay demands, Fin24 reported. According to them, SAA was offering a 5.9% wage increase, to be paid from March 2020. Unions wanted an 8% increase across the board, to be paid on December 13, 2019, News24 reported. Tlali reiterated on Friday the airline was not in a position to offer them anything other than a 5.9% increase.
