The below reference "..to significantly expand the number of U.S. cities that can support commercially viable Haneda service.." will IMO be an important factor in the final DOT decision. My bet is that submissions with JFK/LAX/SFO as the orign will have a lessor weight on an award decision than secondary cities - particularly those with no current Japan service, such as PHL and MIA.
"Daytime access to Haneda has the potential to significantly expand the number of U.S. cities that can support commercially viable Haneda service, in contrast to what is economically viable with nighttime slots. Considering the substantially changed circumstances, the Department believes that the public interest warrants a completely fresh look at the U.S.-Haneda market to determinewhich allocations would best serve the public interest."
