Impossible to find ONE Business Class seat on United, American Airlines, Delta, etc. for the entire summer schedule to Europe
I certainly get it that couples / singles have a big advantage here, and that people want to take their whole family on holidays, but 2 J award seats on every flight is actually a pretty reasonable deal. There are generally always alternative options such as PE (especially on Level to Barcelona) or the full-fare flexible Economy award that opens far more award space on busy flights.
