Air NewZealand and Ansett are doing very well with themselves in the Star Alliance. They have had great profits already and they are continuing to get higher and higher each year.
Thai is also generating alot of profit from the Star Aloliance.
I personally think that one world will soon crumble as they cannot co-ordinate their schedules probably.
They also don't have a pacific market i.e. Star Alliance have AirNZ which basically owns the pacific.
I theink not Aeroflot will join the skyteam!! Not until they get their airline up to scraps with others such as Korean Air and Air France. These airlines are top airlines in the world and donot want there alliance to crumble. I also think Skyteam members are very profitable with Korean Air serving the Asian market. AirFrance serving the European/ United Kingdom region. Delta serving the americas and Aeromexico serving Sout America.
The sky team deserve every success possible.
