Update at ABX.
2 of 6 Aircraft operating for AMZ are retired, remaining 4 will be gone by end of 2024. Loss of block hours (lines), no replacement aircraft announced.
Reducing Atlantic flying (oversea destinations) to once per week. Loss of block hours (lines)
Airframes previous used for overseas will operate hub to ORD and BOS for now

Hiring FO to replace those who have left for other pastures, mostly majors (DAL, AA, etc.), although some to other ACMI.
No upgrades in sight, after settling down from loss of lines/block hours there may be the occasional backfill for a captain departure or retirement.

Seriously consider your options if searching for FO positions, many other ACMI operators offer some version of a future, even those in negotiations (use caution with these as well..).
Advise and comments are worth what you paid for them .
