New hires are mostly going to ACY with a lucky few getting FLL immediately I believe. Seems like FLL is attainable within a month if you don't get it at first.
As of a few weeks ago the most junior line holders in FLL were 01/02/17 DOH for a hard line and 04/11/17 for a relief line.
Can't say for sure because I'm too lazy to look but with as much as reserves are being used these days I don't think many people are doing it voluntarily.
You'd probably be better served posting something in the Spirit section of this forum, just be prepared for the "don't come here" responses.
