Dude, Just call AA and try to find another time which works best for ya giving ya at least 4 hrs transit in between.I guess ya dont go to Nepal very often so bring all kinds of food.you dont have to worry about the time.And another important thing to consider, ya may not be late but its a international flight so ya never know.also, from Nepal to New York its a long way and ya prolly will be burnt out so ya may not wanna hurry at JFK. Call AA and change yo time and be cool.
