I never understood what are the differences between the Chinese airlines that operate Int'l flights.
I know - Chinese Airlines is Taiwanese. That's fine.
But what about Air China, China Eastern, China Southern and China Southwest.
Are they all owned by the gov't?
If so, why the breakup?
are they based in different cities?
do they concentrate on different destinations?
Are they connected in anyway? Any alliances?
Does one have better service than the rest?
