Non-rev luggage charges on UA?

Hi all,
I am planning a trip in summer around the US... I wanted to do most domestic flights on UA but since I am travelling around for about 2 weeks, I was wondering if UA charges standby OAL non rev travelers for luggage?
I work for LH and already talked to UA sales staff in FRA, however, they did not sound too confident when answering my question...
They said "You can take 18kgs for carry-on plus 23kgs for checked luggage on domestic flights when travelling coach class"

Can anyone confirm this???

Thanks!!

From what I've seen here, part of the ZED program is that at least 2 bags at 50 pounds (23kg) must be free of charge. UA employees actually get 70 pounds included, not sure about interline though. If you need to try arguing with someone about that, tell them to check GG PASS BAG around line 50 in the reservations system.

Sounds good!
Thanks!!!!
