NYC 330 B is a different experience than what you will have as DTW 330 B. You will fly places from NYC that you will never get to from DTW. The winter bid pack from NYC has more and better destinations than DTW gets in the summer. The NYC crews have a different mindset about international layovers. It's more about the adventure and less about the $$.
