CXBA.. I really like the way you write. It feels almost right IF (and a extremely huge IF) most of the things you said were actually correct. Sorry to say that, but they are not, and I would advise you to either talk to more brazilian people who travels frequently or come here and see for yourself. So that you can really experience the reality and not only politics that may have happen on the other side of the world or hemisphere. I don't want to be harsh at all, but reply after reply it gets clearly that you made your "business man" idea to reach another level. It feels that you are the diehard fan, but of OW (which I could see why).
I said first and will say again. Star Alliance is still the best option for Brazil right now.
I cannot understand what you mean by mess. And why to blame LH? I cannot really get it at all. Management and decisions surrounding their partner companies such as Swiss I can get it, but not the other ones. I don't think Munich airport is crowded or anything but a decent one to be while making a connexion.

"It was never and will become increasingly the worst option"
"You have to thank the incredible shortsightedness of LH..."
"... now is clear they will never be able to mount a significant challenge to OW and ST"

Man.. I raise my hands to you for being so wrong. These phrases I highlighted are just some of parts that made your reply not valid at all .How can you say things like that?
I am not here to defend LH or other company. Man.. it is just reality check! Right now for the millions of brazilian people who travels, specially to Europe, Star Alliance is still the best choice. A brazillian citizen and member of TAM miles program have the choice to choose which airline you want to travel among lots of them, and not only two (terrible Iberia or British Airways with a great service but expensive fuel taxes). IF the airlines that make part of OW decide to fly to Brazil on a regular basis, than ok. But right now getting just two european OW flights a day in the most busy airport in Brazil is rather ridiculous. Can't you see?
I get the love thing for OW that you posses, but man.. you got blinded by it. I would not give a damm about SA if it wasn't to get thing worse here in Brazil by having the main brazilian airline to join a STILL minor (but bigger than Skyteam) alliance. That's it.



Some other quick points:
1-) Air China really flies to Brazil via Madrid - Barajas since 2006. (go check that and see it for yourself... Start complaining about a flight from another alliance getting into OW territory lol)
2-) I fly to Europe 6 to 7 times over a year. Mostly to Portugal, but I usually(and it is so damm good to have choices, you know) go via LH - Munich. I could go by TAP, but I'd rather get the executive class (and sometimes first) experience of this airline ( but I still prefer Swiss). And I can also go to Frankfurt by JJ. Choices, again, you know? When TAP starts updating the whole of their planes (and get the A350) then I will definitely fly with them.
3-) Iberia has marketed their brand (at least here in Brazil) as "cheap to buy, terrible service". So it has such a bad reputation that the majority of people prefer to pay more money and have better flight experiences. Better and more confort interior and better treatment from the crew . Once again, options. Their neighbor TAP is considered better (and has recently updated some of their old A340 interior) by most of the people, and have the advantage of speaking the same language.
4-) With OW, no more direct connections with Africa. I mean South Africa and South African airlines. But OW is so good that if I eventually decide to go there, I can hop on the British on Iberia flight, then make the joyful and wonderful conexion till South Africa. How great is that? But wait I minute, I can also go take TAM to Europe! Problem solved! And no more Air Canada... but hey, American Airlines will probably solve this one.
