TSA Pre-Check and Global Entry allow passengers to more or less avoid the full-body (millimeter wave) scanners and instead use metal detectors. You also don't have to take off your shoes or take out your laptop.
This is an important benefit to many of us -- even more important than cutting the line. But TSA Pre-Check and Global Entry are only offered to US citizens, permanent residents, and citizens of a restricted subset of countries. The rest of humanity is SOL.
CLEAR seems to offer a solution as you only need a USA driver's license to apply, which means F1 students or H1B workers from any country, for example, are eligible.
But I'm unclear about the benefits of CLEAR. Do you get the same pre-check benefits such as avoiding the full-body scanner if you don't have TSA Pre-Check? If you don’t, is there really that much benefit?
