I live in RIC and only FLy delta. Have done this trip 3 times in the past year and 2 more in the next 3 months. Great flights and plenty of time to xfer. I know 5:30 or 6:00 is early but no lines in RIC that early. JFK layover return ( this is cheaper ) is a little dicey especially in the winter and the smaller plane. Tons of places in Atlanta airport to eat.
