I had CLEAR about 18 months ago on a free trial (which I had deactivated after free trial was over).
Today, I signed up with the same email/same phone number etc for a new 4-month free trial account (tripit code) - and surprisingly it went through. The only hitch was that my online account was still showing de-activated because my email/phone was associated with the older deactivated account, so i had to call in to a very friendly rep to get that fixed up.
So this begs the question - given that CLEAR keeps coming out with 3-4month promo codes, can I theoretically churn these codes forever? Or was my experience just a fluke in the system and other's experiences have been different.
