Gentlemen, you all must understand that this is not about Aer Lingus or UAL making money on the IAD/MAD route. Open Skies is not about competition or free consumer choice. It is about driving labor to the lowest common denominator.
Utter rubbish. Openskies is designed to permit greater consumer choice, and allow move flights to more destinations than has ever previously been possible.
However, reduction in labour costs is clearly not an aim of the treaty, largely as flight crews remain tied to carriers within the USA / EU respectively.
