Security cannot agree to mail everyone's thing to them, it's not an option. You can mail things to YOURSELF, if you are prepared for the situation. For me, a plane ticket costs more than my skates, so I'd let the skates go. I might even ask if I could just unscrew the blades and throw them away... boots aren't dangerous. I keep a small screwdriver in my skate bag. I know elite skaters for whom their skates are much more valueable, in which case they probably would have gotten out of line to check the skates and hoped they could get back in time for the flight. If the line was really a 2-hour wait, she shouldn't have chanced it, but even still, she could have gone back and checked the skates, and done her best to get back through in time for her flight. Generally- if you let the people in front of you know you have a flight already boarding, they let you through. A 2-hour wait is quite atrocious, and many people probably did miss their flights, as I believe airlines tell you to get to the airport 1 hour ahead of time. The thing is, even things that are on the permitted are left to the whim of TSA agents, and the TSA website says that. Skates are a gray area already, since they are in neither list. If the TSA policy makes it "clear" that you can't know what to expect, why would you attempt to get through with something most people are shocked is ever allowed. Skates have a sharp blade on them. When left to an individual decision, most individuals will decide it is dangerous, regardless if it has a guard on it. Guards are pretty easy to remove!
