As local residents we used to get free tickets, not anymore. This was a thank you from the organisers for the disruption to normal life for a week or so. I'm not complaining, the show brings much needed income to the area, but the free tickets were a welcome gesture.
Once you have paid your entry fee, the price of food and drinks is eye watering.
Lots of people watch from the corner by Barons BMW, or the Swan does a package where you can watch from their deck. I think the ticket includes food.
Good views from MOD ground at west end of runway, but be prepared for a long hike or mountain bike to get there as all local car parks and many access areas are cut off for the duration of the show. Excellent views from top of Caesars Camp if the military do not cut it off. I have also viewed from beside the tower on Tweseldown, but I suspect the new owners may put a stop to this.
I will probably be able to see enough from my back garden!
