I thought the argument here was over subsidies, not about open skies agreements.
The ME3 aren't subsidized. They're owned by the (private) government.
Similar to many other flag carriers. Yet I don't see Delta arguing for restrictions on South African Airways or PIA etc.
Its only because the ME3 have a better product at a better price, and are killing the weaker competition that the likes of Delta are squealing.
Delta et al arguing for the US government to restrict these better performing airlines is in effect a request for non financial 'subsidy' isn't it?
