I have a Clear membership thru 12/2009 and have yet to decide if I will renew it for $159 after that date--the non-discounted price would be $199--even tho the original cost was $100_+ $28 TSA vetting fee (increased price big time--gee, surprise!!)

I fly frequently [w/out benefit of airline ID] as employee spouse so it averages less than $10 check-in--I use all 18 of my TO's which means 9 in CVG, If I have to opt for LGA instead of JFK to make start my TO connect they offer it at Terminal 2
JFk, so I skip right past everyone to the machine and it is VERY COOL!!! and efficient this way. I fly an additional 10 domestic legs--all out of CVG. Unless in uniform, there is no express lane to TSA nirvana at CVG, so that's the benefit I enjoy.
I can only hope they increase the airports that are served by clear but if everybody's uncle is doing it, whooppdeeedoo...
