Been there twice, awhile back and last year. While I just bought tickets at the gate, the only real difference I saw between the special seating and the regular admission is that you receive a folding chair in a reserved section up front. I had great views from my lawnchair and was close to the runway so I would recommend against the 10 bucks since you can get equal seats if you arrive early and bring your own chair. I would be there this year again (since I live 20 minutes from the airport), yet alas I'm in Europe during the show. Enjoy the Snowbirds, Thunderbirds, and the many other preformers. It's trully a world-class airshow!
