United Airlines has opened the business class award floodgates on several flights between the US and Europe for next summer with as many as 9 (and perhaps more) award seats per flight.
This is especially concentrated out of Washington Dulles, though there are some flights out of Chicago like this and even a few from Newark. It’s especially true on flights that have recently been upgauged to Boeing 777s, though not exclusively. (Legacy United Boeing 777 business class is dorm-style 8-across, but if fully flat.)
