oneworld has always stated that they preferred quality over quantity, and this shows in the current memberships of the OW vs Star. (Can't talk about SkyTeam, don't know enough about them).

Whilst Star certainly has some quality airlines (SQ, TG, NZ, for example) there are some real dodgy ones in there as well, which you would expect with an alliance comprising so many carriers.

OW on the other hand has a fairly high quality quotient. AA is certainly not THE best USA carrier (which is probably CO nationally, and AS within their own niche market) but it is up there, and certainly better than most of the opposition. The rest of OW (IB notwithstanding) are all top notch carriers, which serves to demonstrate that OW will not expand merely for the sake of expanding. They will do it if it enhances the alliance, while Star seems to want to expand at any cost.

I think OW should continue down the course they have set themselves, it seems to be working.
