Permission for post Covid isolation travel with Recovery Letter

Really disappointing that you have not got yourselves up to speed regarding COVID requirements for travelling. IATA is clear on requirements for passengers travelling post covid and making provision for the Recovery Letter as per the latest practice. Yet your passengers travelling back to South Africa haveto go to the ends of the world to get authority from the Health Department, from Immigration, etc. and still not being guaranteed of being able to board. Instead of you, KLM, just acquiring and applying the most recent practice of allowing passengers to make use of travelling with a Recovery Letter as well as the required PCRs and doctors approval - as this is permitted in South Africa. Over and above this there is no way that we, as the passenger, can actually speak to anybody, we can only make use of virtual assistants and social media that give us general information that does not assist with the specific issue. Please up your knowledge with the most recent travel practice as per IATA and South African Health regulations which permits post covid isolation travel with a recovery letter.
