OR Tambo International Airport (Johannesburg), is now enforcing new checked bag rules which state that bags must follow the following criteria in order to be checked in: Bags must be regular-shaped with at least one flat surface. In addition bags with long straps or handles will not be allowed. But don't worry - you don't need to buy all new luggage. There are baggage wrapping stations at the airport which will (for a fee) wrap your bags according to these new rules. Or save yourself a few bucks and some time, and get them ready at home.
