xx-UA I-D is generally 80-105 minutes (but without Global Entry this is very tight)

Incoming International (except Canadian flights arriving as domestic flights - clearance is done in Canada) - must clear USA immigration and customs even if in-transit to a non-USA destination. Therefore also need to re-clear security if connecting.

Bags can be check at either International Check (G) or Domestic check-in (T3) for either international or domestic flights -- you may get some pushback at International check-in counters checking bags for solely domestic flights (apparently it is a bit more complex to get the bags to the domestic side)

Bag storage Open Everyday 6am – 11 pm
Before security, on the Departures/Ticketing Level of the International Terminal, near the entrance to Gates G91-G102.
