Interesting to see how much it costs. I fill up from Coventry before I go anywhere, and have never been so far that I've needed to fill up before coming back. I don't even get to see how much Coventry charges because it goes on the flying group account.
At the Popham fly in I got a flight with a couple of PPRuNers who were 'popping to Sandown to refuel'. I guess if there's a big difference it's worth the trip (plus it was a gorgeous day, and I'd never been to IOW before
)
