Airline partnerships are not only beneficial to the airlines themselves but also to passengers. With competition as a driving force within the industry, some carriers agree to join forces not by merging but by allowing passengers to book their flights through their partners’ websites. Many of these famed partnerships are between airlines that are part of the same airline alliance: oneworld, Star Alliance, or SkyTeam. The collaboration allows passengers to fly further than ever before, as carriers can significantly widen their route networks.
