I commuted from ATL-JFK for 9E. I chose JFK because I could use either JFK or LGA. JFK got more and more difficult and I wound up using LGA the majority of the time. This was a few yrs ago but DAL had an hourly nonstop ATL-LGA and only about 6 per day to JFK. We had an ATL base at 9E back then but it was senior and I couldn't hold it.....then it closed.
