Three global airline alliances include 82% of the world's top 60 carriers

Oneworld 21.6% (ie: American Airlines)
Star Alliance 27% (ie: United Airlines)
SkyTeam 22.5% (ie: Northwest Airlines)
Unaligned 28.9% (ie: JetBlue)


All three airline alliances are seeking to sign carriers out of such emerging markets as China and India.

For the consumer, the added benefit may be more opportunities to earn and spend frequent flyer miles with airlines in each alliance without having to belong to each airline's frequent flyer program.
