TAAG 747 JNB-LAD and is maintained at SAA. Plenty of trips there and no real probs. 737s different story... had the dubious pleasure of pax'ing on them once- i recommend heavy duty rosary beads. Adding to the story above- when in Lubango they saw that part of the wing tip was missing and even STILL continued on to LAD...
Do you ever wonder why the pax cabin normally erupts in applause after touchdown on these airlines..?
Reckon they know something we don't?
