I'm surprised more airfields don't offer "associate membership" like they do at Old Buckenham. The landing fee is around £12 for a single which isn't too bad as the facilities are very good and the refurbished cafe is excellent. However for £20 you can join as an associate and have as many landings as you like in a calendar year. Only 2 landings and you're ahead of the game. As this is my favourite "£100 coffee" flight it works well for me and judging by the other posters in this thread Kemble gets a lot of return visitors as well so it could work there as well.
