Well, since there are no slots available and probably will not be for a long time, since the new entrant US carriers would go to the bottom of the queue, then it is tantamount to offering nothing in return for open skies in the US.
So I ask again, what is in this for the US, since I am unable to see an upside? So yes, status quo seems a better deal for the US airlines, as unfair as you may find this to be.
