I am confident that "Some day" they will get their anti-shoe-taking-off technology greenlighted by the TSA (they've been denied twice), and then it will be worth it. I've had it since almost the beginning, and I have to admit that it's tough to justify. However, I will still renew. I fly out of SJC Terminal C every 2 weeks, and there's no elite line there. So, for the rare times when there is actually a line, it is useful. It's slightly humorous how there are so few people who have it. Almost without fail, as I'm walking up to the Clear line (at any airport), they immediately start to direct me to the normal line. When I ignore them, they get a little nervous and ask if I'm a Clear Traveler. When I say, "yes", they are pretty surprised.
