Update for SFO, Terminal 1 DL gates (40-48):
They just expanded and reconfigured this checkpoint. The regular lines now snake through what used to be the seating area of the food court before arriving at the Pointless ID Check™.
There is now a new checkpoint lane to the left of the existing lanes. The exit from airside has shifted over in to what used to be a shop. So the configuration is now
- New lane (far left): WTMD only (at least for now -- there appears to be space for a NoS). This lane is fed by the priority lane, though you might be able to cross over to it.
- Existing lanes: Two WTMD and MMW pairs. Each pair has two bag scanners. Sometimes they run the lines so you go through the device closest to the bag scanner you picked, but more often (IME) they randomly assign you to WTMD or MMW.
All in all an improvement, at least until the third MMW shows up.
