If this idea has been mentioned before, then please disregard.
Flew Friday morning. Checked local fuel prices before the trip and found $3.65 on my route. Stopped for fuel - it had gone up a bit. (Manager said it had been at the higher price for a week.)
Interestingly, after I landed, I rechecked the prices while on-line at the FBO. This time the price was correct. I don't know how often the data base is updated and/or updates sent out over iFly. (The new fuel price on iFly (on the GlobalAir page) said that price had changed 8 days ago. So - a dumb question: Does iFly always update fuel prices when I'm on-line, or only when I've got the Fuel Price layer active and am on-line? 'Cause, IIRC, I saw the lower fuel price when I was checking prices Friday morning off-line.)
Anyway, thought it might be cool for a check box somewhere on the Airport Info page that asks "Is this fuel price correct?" If not, then perhaps users could enter the correct fuel price and iFly could send it to GlobalAir? (Probably same check boxs or a corrections page for all the other stuff too. But fuel is the primary thing.)
