For you poolies, the following are the total "vacancies" and the percentage of each category that were left open after this AE closed. Two caveats, these numbers are only as good as my math, and they are written in sand, as Delta target numbers change often.

ATL73N - 7, 2%
DTW73N - 26, 20%
NYC73N - 35, 20%
ATL320 - 18, 10%
DTW320 - 56, 33%
NYC320 - 61, 50%
ATLM88 - 88, 15%
NYCM88 - 107, 52%
ATL717 - 43, 19%
DTW717 - 35, 35%
LAX717 - 6, 8%
NYC717 - 101, 60%

Of note; over half of the projected number of F/O seats required for NYC320, M88, and 717 will be available over the next 6 months. So if you are looking for the fastest rise in seniority, those MAY be your best bet in the short term. As always, aircraft deliveries and retirements, and some of the planned airport gate expansions (most notably LAX and SEA) will have big impacts on these projections going forward.

Good luck, and welcome to Delta.
