Their metal detectors are still weird. Only place I never had to take off my old jacket as every other place it would trigger (Cape Town, Dubai, Vienna, Zürich, Amsterdam, Heathrow).
Just flew back to South Africa for a few weeks on holiday, quite noticeable even in CT international how it's Africa. Things like the sign for the airport on plane side says "Cape Town Internato Airport", rest of them don't light up.
Health questionnaire but no pen, temperature measurement with separate equipment instead of the thermal cameras they already have set up, and constantly issues with them with battery or something. They added electronic gates for SA passport holders, but all closed/not able to be used, so constant issue of having to shout and get everyone from that queue to go to international queue, then if queue international some get to skip if South African but others not, etc. And you get stuck over 45 minutes for a process that should take maybe 5-10 anywhere else and they still can't get all the baggage onto the conveyor belt in that time.
Europe the electronic passport control has been in place and working fine for years already, South Africa "swaps" and then doesn't use it.
At least still better than Johannesburg. There is that nice half bar there, forgot what it's called, only nice thing there. Still remember driving back, dropping off rental and get told not to interact with dude on other side of parking lot as known conman working with gangs to hijack people, and I'm just standing there wondering how he hasn't been kicked out of an access restricted parking lot, have never even heard of that happening in an airport anywhere else.
Sorry, side rant all of that, I fly too often internationally, most people will never understand what's wrong with most of SA Airports until they try others.
