Identification of Minors

I recently booked a flight to Bloem. When I arrived at the airport they would not allow us to fly as we did not have the unabridged birth certificate with us, for my daughter.<br> I was informed that they do not accept the medical aid card it must be the Birth Certificate.<br> I was informed that this \as been for some time."<br> Point 1<br> It has not been \""for some time\"" because we are regular flyers"
