100LL.com has consistently beat Airnav.com on price accuracy and
timely updates for all of the long cross country trips I've taken
during the past 2 years. It's saved me more than $1000 over what
Airnav found for lowest priced fuel near my destinations.

Interesting. While Airnav is often incorrect (old data), 100ll.com is
more often incorrect in my experience. Certainly, 100ll.com appears to
be consistently less accurate just in my local/regional area.

In any case, I've concluded that the best method is to find the airports
with low price trends, and then call them to get an update on prices and
availability. During the post-Katrina run-up, the cheaper fields
quickly sold out and, because they didn't raise prices with the market,
couldn't afford to refill the tanks until prices came back down again.
It would be a shame to land somewhere with legal reserves, only to find
out that their tanks are dry.
