ARR72, welcome to FlyerTalk. As we have a consolidated thread for United connections at EWR, I'll join this thread with the consolidated one so that you'll be able to see others' experiences in connecting at EWR. Ocn Vw 1K, Moderator.
Do note the concern members' expressed about your changed destination of SFO rather than the original one of LAX. If you are concerned about this change, I'd recommend that you start a separate thread so that members can discuss and assist you, if you wish it.
