My nephew is flying LAX to EDI, and I'm trying to help find the easiest route for him.

If he flies UA LAX-EWR-EDI, will he need to change terminals in EWR? Will he need to re-clear security in EWR?

I'm hoping the answer is no to both!

Travel is on September 1st
UA 1691 LAX-EWR
connecting to
UA 36 EWR-EDI

(I used the first flight number on UA's site looking for gate and terminal info for next Tuesday's flight, but it pulled up flights from CUN. So I'm assuming there'll be a switch in flight numbering between now and then.)
