I too love the like a concert seat ticket thing.

Lets see, if I don't want to see the opening act and just the main act, I can show up late. Try using only the second segment of an airline ticket

I can give my ticket to somebody else if I can't use it. Try that with an airline ticket

I can sell my ticket if I have to, again can't do that with an airline ticket

I am 100% guaranteed a seat, when was the last time a concert was overbooked?

I have a decent variety of food and beverage choices, though it will cost me, it's my choice

I've never had a checked bag at a concert not be there when I went to get it

If I don't like the show, I can leave early, and come back again later

I can get a full container of soda, and don't have to beg for a plastic knife.

Security at concerts is much better then security at airports for catching stuff

I can leave my cell phone and pager on the entire show

I can park and get to my seat in about 5 or 10 minutes, without taking off my shoes

If there is a show I want to see, and there are still seats available for next week, I won't be paying fourteen times what somebody did two weeks ago to sit next to me.
