Airlines just don’t respect customers anymore

My husband and I returned from a lovely holiday in mauritius just to arrive back in SA JHB for our connecting flight to CT to find it terribly delayed at an airport that is fast asleep by that time. Everything starts shutting down from 20h30. The flight was supposed to leave 21h15. So it is really incredibly frustrating if such a late flight is even further pushed out. After an initial hour delay I am sitting 5 months pregnant, very tired and stuck on a plane that is fighting with the airport to get refueled. To make it even worse on the plane it was announced that this plane has been behind schedule since its first flight this morning due to repair work to the engin. We were not made aware of this earlier neither did the airline try to make any effort to help all the passengers unknowingly get stuck at a ghost airport. So now we wait still ... 22h30 ... our lift on the other side will be fetching us in the early morning hours. What a bad way to end such a lovely holiday ... is there no respect for a good customer experience anymore? Flight tickets are super expensive ... am super frustrated!!
