I love SJC and find most everyone to be friendly. The TSA situation in Terminal B is pretty confusing and unpredictable though.

Whenever I have flown Thursday/Friday evenings, especially near 3-day weekend holidays, the line is very short. Usually less than 5 minutes but my flight is packed. Whenever I fly during off peak hours (mid-day weekday and weekend) the line is long but my flight is half empty.

The only thing that made sense was my recent flight at 9:30am on a Friday. The line was about 30 minutes and even PreCheck was backed up.

The logistics of flying (getting there in time via public transit, TSA lines, Southwest's boarding process) makes me nervous, so for me Clear is looking like a decent option even though in reality the line is really not bad at all.
