Pretty much all of my travel is out of Terminal 4 and I've learned a few things that may make your life easier:
If you're flying American and aren't checking bags, don't worry about stopping at the kiosks by the counter to grab your boarding pass as there is another kiosk up the escalator that no one ever uses.
Also, if you're taking an Uber or Lyft, you can find your ride outside Door 1 North or Door 8 South at the outer curb.
