I travel a lot for work and for me it is Atlanta, Orlando, Fort Lauderdale, and San Franscisco. But if you rarely travel I don't think it's worth paying the money for it. But if you do travel frequently, I would get TSA Pre-Check and Clear. What would have taken me 30+ minutes in just pre-check line alone literally only took me 45 seconds. This was in Fort Lauderdale recently.
