Note that UA has a curbside skycap checkin but it's not obvious since it's at the far south end of the C lobby, past the walled off construction zone. There's a narrow plywood hallway that connects lobby to curbside, down where the TSA PreCheck lane is. Last couple times I checked baggage with UA that curbside was empty - the signage makes people think they need to enter mid-terminal where Southwest is and they never realize there are UA skycaps at the far end.
