In the early days of aviation, there was no concept of airline alliances. Airlines built their own networks, sold tickets for their own flights, and competed largely on the destinations they could serve. That, however, has changed significantly over the past few decades. Airlines are consistently seeking ways to strengthen their global presence and remain competitive, making alliance membership an increasingly attractive strategic move. So in this video, we take a look at how the oneworld alliance decides who gets in, why founding airlines hold extraordinary influence, and how one airline executive can block a carrier from joining, even if the rest of the alliance sees clear benefits.
