majority of JB flights in JFK are outside the time zone for slot controlled period. Currently only DAL does anything as a fight with JB, AA just sitting on the side licking its wounds. If AA wants to (in JFK) it has ample slots to complete on a better to travel time for passengers and anything before 3pm in JFK is non slot. So AA could compete against JB on any route before 3pm to 8pm (slot period) without giving up any slot usage. All it takes is balls.
