PRM handling was my first airport job in one the the major international airport in Africa AKA Wakanda kingdom. Its a lovely job and it makes one to appreciate humanity and to love the most. It most cases I know it's an airline job to organize for the processing of PRM passengers. Some airlines do it directly while others do opt for a third party contractor to do the job. WCHR is never that serious and so in most cases may not need DR clearance but just a notification to the airline. WCHS in most cases are those with medical conditions and so they need Dr clearance and the DR must be recognized by the airline you are flying. That job was sweet and it made me to understand disability and learn more about extreme medical conditions
