Electronic ticket partners

With the implementation of Interline Electronic Ticketing (IET), passengers travelling on more than one airline can travel with one single electronic document. Air Canada currently offers Interline e-tickets with most of its Star Alliance partners as well as many other carriers, thus offering its customers a global, seamless Star E-ticket product.
