Sending my 15 year old later this summer from RNO (Reno)- LAX - PDX (Portland).

He's traveled numerous times, but not by himself.

Question - Do the United Express flights all leave from the same gate area at LAX? The flights that we're looking at have a 30-35 minute connection time which would seem to be enough (hoping that it's not like ORD and trying to go from F11 to C28)...

Thanks
