Clear is a company that makes it possible for you to save loads of time as you check in for your next flight at the airport.
A six-month membership is $79.
This fee gets you a personalized ClearCard, which works with Clear kiosks at participating airports.
After inserting your ClearCard, the machine will verify that you are who you say you are by scanning your retinas and fingerprints.
Once confirmed, you get to hop to the front of the security line. You don't get to skip security, of course, but you don't have to while away your time at the back of the line.
There are other frequent-flier programs that offer similar functionality, but those tend to be airline-specific. The difference here is that it's airport-specific. So if you frequently fly out of a participating airport, this might be a good investment for you.
Clear is currently supported at Orlando International, Denver International, San Francisco International, Dallas/Fort Worth International, and Westchester Airport.
