And why should this be dealt with differently to AF/KL/DL/NW?
Because currently, AF/KL/NW/DL are not planning to cooperate to the degree that BA/AA appear to be planning to.
Considering that the report refers to specifically the "no foreign airline can own more than X amount in US airline" clause that gets the US authorities so hot under the collar whenever a Euro airline is interested in a US counterpart, this definitely smells of a lot more than just code-shares and route optimisation, but rather a merger of sorts.
And SRB is doing exactly what any other airline owner flying the same route would do, try to oppose any advantage that his competition gains by merging with another.
So yes, while it may look like he's moaning and complaining, and perhaps he is, he is safeguarding his revenue stream, which may or may not be threatened on four specific routes (some of which he only recently started).
