Last time I landed at bomo and stayed over night it was £47.31
I think I was charged extra for arriving after 6pm though. We have students do the qxc's into bomo and a straightforward landing is about £23.
You could try Bournemouth Flying Club. They used to let you pay the landing fee there and park for cheaper. But space is very very limited now, and they've probably stopped that practice. I haven't heard of them letting anyone park for a few years now. The other ppl school is situated exactly where the GA parking area is so they are of no help unfortunately.
As for Compton; It is £8 to land and £5 for overnight parking, but a taxi will set you back a hell of a lot. It's about a 45 min drive to the centre of bomo, and that's really going some.
Phone Compton though, and ask about the 'hire' car. It is available FREE (just fill it up with petrol when your finished) to anyone who wants to get about. However, you need to have certain insurance and licence requirements. I can't remember the requirements now, and they might have even got rid of it, as it wasn't very well utilised.
As for Sarum, I’m not sure. Is about a 30-45 min drive to bomo from Salisbury.
Hope that helps.
