If you’re looking to get out of the northeast hops, it’s the 320 without question. While I’m not JFK, my stage length seems to average on 3 hours block or so over a year. My shortest flight is typically a northeast to Florida type route. On legs per day, most common is 1, occasionally, but not rare, is 2. I’ve seen 3 less times than I can count on one hand and done 4 legs 2 times and it was all west coast and worth 8+ hours.
