Seems like a well orchestrated chess game. AA&US management were in bed all along. US/DL LGA/DCA slot swap (DOJ would have never approved the deal with AA @ JFK and US @ LGA), US becoming an insignificant member of STAR, both AA & US dragging their feet w/ negotiations, AA's bankruptcy and AA's offer to APA (knowing well that APA would never accept).
If US would have come out and asked for a merger-the unions would have cried bloody murder. But let AA offer them a crappy contract and they'll go running to US.
The APA letter makes the US management look like a knight in shinning armor, but ignore their treatment of their own pilot groups. IMHO US&TWA guys are gonna get the short end of the stick on this deal ... again.
