For me it's not a question of getting there sooner but avoiding the inconvenience of taking off my shoes, taking out the laptop, etc. For anybody I frequently travel with though, I would advise them to get precheck and I would pay for it myself if they are not financially able to.
That's how I would handle the situation as well.
So, if I am flying with someone on a regular basis, we would get TSA Pre-Check, CLEAR, and GE for them.
TSA Pre-Check, CLEAR, and GE are definitely a convenience that I enjoy using.
Also, in the event that I am in a premium cabin
, and for some reason the person I am traveling with is not,
,
I AM going to offer to switch seats with the person I am traveling with (well, probably 95% of the time
).
That should help the flight part of the travel be really cool!
