Its been 9 months since i used GE for its intended purpose (I mainly use it for pre-check). I went through SFO and it went well. I was upper deck 747 and i took my time getting my things collected. I was one of the last to leave upper deck. Had time to stroll to the restroom to freshen up.
By the time I was ready to head to the kiosks, i was blocked by a wall of people lined up for immigration. If it weren't for the fact last time i cleared it was at this airport, i would have had no idea where to go. After spending a few min pushing through the mayhem, i made it to the kiosks which were empty.
The instructions on the screen were helpful as i couldn't remember the process from my last use. I received the receipt with my photo and walked past one of the the agents handling those without GE. I noticed my seatmate was standing there getting ready to answer whatever questions the agent had (should I have told him to sign up?)
After clearing immigration, i made my way past those waiting for bags (carry-on is key). The exit for customs had 2 lines (both barely had people). One lane was for GE and one for everyone else. The CBP agent scolded a crew member that used the GE exit lane when she wasn't a member. After that i made my way to TSA to get back to to my domestic flight. If only Pre was allowed on the final domestic segment, it would have made it perfect.
