I'm on the 200. A typical four day is 5,4,4,3 or 3,4,4,5. Sometimes 2 legs on day 2 and 3. Shorter flights (longest block times are around 2 hours. Average is 1:30. I'd imagine the 900 has less legs. You'll probably get more block time on the 900 but a quicker line on the 200. Although in NY the difference between line holding on the 200/900 can't be much
