On Saturday Oct 14 it took me 45 minutes from the time my LH plane touched down to walk quickly to the Flight Connection Center, go through the short security lines, check in at the UA desk and get rebooked since I missed my connection, take the bus to Terminal 3 and walk to the Red Carpet Club. I went through security a second time, I suppose at the entrance to Terminal 3, and there was no line at all. At that one, they opened my bag and briefly peeked inside.
