Which airline alliance was launched in 1997 as the first global airline alliance?

Star Alliance was launched in 1997 as the first global airline alliance. Its founding members were Air Canada, Lufthansa, Scandinavian Airlines, Thai Airways International, and United Airlines.

The alliance was created so separate airlines could cooperate across international networks. Benefits can include coordinated schedules, shared airport facilities, reciprocal frequent-flyer recognition, and lounge access, although the exact benefits depend on ticket type and membership status.

Star Alliance’s launch reflected the increasing importance of connecting passengers through airline hubs. Oneworld followed in 1999, and SkyTeam began in 2000. An alliance is not the same as a merger: member airlines remain separate companies, operate under their own brands, and generally keep their own aircraft and management structures.
