52 Slots divested at DCA, of which 8 are already subleased to JetBlue, which would equal the net loss of 44 slots.
AA also does not have to "give up" the slots, but can lease them to an APPROVED carrier with limited service into the airport. Which means that if DL and VX are the only two carriers that apply for a given set of slots, VX would more than likely be the operator to win them.
17 slots are being given up at LGA, which could be taken care of by up gauging, and reducing frequency of some of the "Shuttle" flights as well as lopping off a couple more small stations and eliminating duplicated routes like DFW/ORD/CLT.
All of the rest of the divestitures are only giving up gate space, which will not greatly reduce the number of frequencies. Especially when you keep in mind the number of duplicated hub to hub flights that will be dropped. And consider that AA still had not committed to a schedule out of DAL when Wright restrictions are eased.
