You have to send in all the paperwork (I did it electronically) and wait to get through the first round of screening which takes a couple of weeks, then you schedule an interview at one of the locations (I did mine at the nearby international airport). The interview takes less than 30 min, including them showing you how to work the machine and putting the sticker in your passport. It's $100 for 5 years, and it is a pilot program. So right now it's not available in every international airport. I've already used it once. The flight that made me decide to get it was an experience like yours, where several of my friends missed their connection and we had to race to get to the gate. The first flight when I actually got to use it, the program got me no further ahead than my friends. So, it truely is random but for that one time when you need it, if $100 is worth you making your connection I say go for it. Just keep in mind that if you travel with friends or family and you are the only one who gets it, it only works if you leave them behind.
