Since the pay increase including boarding pay has gone into effect I've noticed a definite increase in chances of pdbs. AA seems to be trying to do a better job of communicating delays whether by app (technology) or by human (gate agents). That being said the tools are generally there for self help or at least to determine what your best alternative is during irregular operations. But even experience FF will depend upon a stressed out, overloaded gate agent or lounge staff to figure out their alternative. And since their time is limited (a line behind you) they are going to give you the first thing that pops up on their computer screen.
