Yeah, well, being originally a German converted to a Swiss, I have been living quite a few years abroad (mainly UK and Germany). Let me tell you...bla...bla...
Oh well, let's not start on political/racial whatever issues.
To put the record straight, I really don't think foreign airlines are at disadvantage in Switzerland, actually more the other way round (at least during flight ops, not talking about ground structures I don't know about).
