We flew USAir in November 2002. USAir has 2 kiosks in Syracuse. They are to the left of the waiting area. Don't get fooled and wait in line. We had a problem using the kiosks in November but only because they changed our flights and then I had to go and have them re-change it because they gave us some crappy flights. The kiosk could not "find" our ressie. However, an attendant took us right away and took care of everything. I think the kiosks save a lot of waiting in line.
We have never had a problem with the security. They seemed pretty efficient. We flew, as mentioned, in November and again in February. Both times they had to open my purse to look in and both times it was because of my eyelash curler.
