Okay, that's good to know. I have a spinner and usually put my backpack over the handle. I find it slightly slower to push my bag over carpet, and I think those walkways are carpeted, yes?

But my real question is whether the CL is less crowded. Particularly if there is no security near the CL, I would imagine a lot of pax who aren't super familiar with SFO would not know to pass security in international G and instead pass security in T3 for domestic flights out of the E gates, and those people might give up on the CL.
