South African Airways and Alaska Airlines have established an interline partnership, enabling travelers to book travel on a single itinerary across both carriers. That means a single check-in process and seamless baggage handling on SAA flights that connect to Alaska flights at SAA's U.S. gateways—New York's John F. Kennedy International Airport and Washington Dulles International Airport. The same goes for itineraries that begin on Alaska flights and connect at those airports to SAA flights.
