British Air Comair

My flight to Durban from Jhb On Wednesday 7th April 2021 13h30 delayed (without notification prior hand) for 3hr15min.Return flight for 10th April booked both 13hr15.Arrived at airport (King Shaka) 2 hrs beforehand ,looked at the departures only to see? You guessed it.Flight delayed until 16h30!!!!!! (Also without notice).This the 1st timeI have flown BA and the last.Terrible situation. The flight numbers for these flights are BA6207(Jhb to Dbn) and BA6212(Dbn to Jhb).Avoid these flights at all costs and maybe BA itself.
