It doesn't pay as much as the 73N, requires a long training period at Natco, and I see many people currently commuting to DTW bidding ATL if it is closer to their home. Same with the A330. A lot of A330 pilots live in FLA and do the one monthly commute to DTW to start and end a 12 day trip. I would think ATL would get very senior on those two planes, with DTW opening up.
