Quelle surprise! 
This is a complete non sequitur.
SEA-Flyer's problem is linked to the
absence of an agreement, not to the existence of another one: what he would need is fares that allow interlining agreement between VS and AF on this route or at least allow end-to-end on each other.
Even if there was zero agreement between DL and VS and zero agreement between AF and DL, that would still not in itself provide a solution to
SEA-Flyer's problem.
