Ya things are definitely getting interesting. Here's the catch 22: They need to upgrade FOs to fill the spots for all the Captain attrition. However, because they are so short on FOs, they can't afford to upgrade anyone to Capt. until they get new FOs. They can't get new FOs because the schedules are so bad (from the low staffing) and no one is upgrading to Capt. here (among other things). No one is upgrading to Capt. because they can't get FOs....and so on
