Answer, this is how it's always been. AA is mor them keeping change post CV19. After CV19 a long connection (or overnight) could be required between even big cities. AA (and to lesser extent UA) Just never went back. DL OTOH has been trying real hard to reimpose the 4/6/24hr rules. (6 for Central America/Caribbean) The 6hr rule seems to be biting them. The routes it is on a lot have no same day connection.
Regardless 4 hour has just been the long established norm for DTD connection.
