Three years ago, it took half an hour to get onto stand, a further half an hour to get the door open and people starting to get off, and over an hour in immigration, with ESTA. If there were automated kiosks, nobody from my flight found them...
It then took a further hour to get past the TSApes.
I had a 4-hour connection, and it was unpleasantly tight.
That was whatever terminal AA and AY use (T8?).
Let him that hath understanding count the number of the beast:
For it is the number of a man; and its number is One hundred threescore and twelve.
