Benefits: next to none. Yes, you skip the first line to check ID. So you think you've saved like 5 min tops. Then you're confronted with their computers which can't handle anything that's not happy path.
You still have to do the regular line of no shoes, no belt, etc.
Save your money, don't subscribe to Clear.
And if you travel a lot or plan to, just do the airline status challenge and get priority boarding.
