Advance Entitlement (AE) has open positions available for everyone on the seniority list to bid.

Whatever positions don’t get scooped up will be offered to noobs.

In your notional new hire class of 50 pilots, they aren’t going to tell you there at 10 NYC 767-400 slots and 40 NYC A220 slots.

They will just provide you with a list of bases/plane combos that are available….767 and 220….no number of positions will be provided to you.
