I've read the text of the agreement.
AA gets to sell the slots to no fewer than two buyers.
The 10 slots at LGA already leased to WN go to WN, so they get to transfer the ownership. Likewise for the slots at DCA that Jetblue was already leasing from AA.
The remainder? It's unlikely that AA would be selling anything to DL or UA.
My read is that AA gets to collude with WN and B6 to carve up the remainder of DCA. Nobody else will have the cash to do so, certainly not NK or F9...
AA is giving up L1/L2 at ORD, but gets to keep the US gates over on E/F.
At LAX, they're giving up two gates in Terminal 3 (I'm sure DL is doing a happy dance on that), but as mentioned, the capacity at TBIT is a wash.
The agreement also requires giving up gates at DCA to make it work, and it looks like they chose the AA gates to sacrifice. (Up to five (5) gates from among Gates 24, 26, 28, 30 and 32, if necessary)
The agreement stops AA from reacquiring the divested slots for 10 years, but doesn't seem to block them from buying other slots @ either DCA or LGA on the open market.
Unsaid in all this: the only jobs lost are at DCA. The number of slot pairs probably equates to a couple of ground crews which would likely be attrited out instead of outright layoffs.
The only wrinkle left is if the anti-trust judge finds the terms too lenient. Judges don't have to rubber stamp a settlement, but she probably will.
