I would hedge only about 10%-20% now, and then 10% or so per month for the next 10 months.
I don't see the point of a 100% all-in hedge unless you are SURE fuel will never go any lower (and really, when can you be sure of that), and it exposes you to the possibility for error illustrated above.
If you hedge 10% per month for 10 months rolling, you will still be protected from unexpected huge spikes. Becuase you will pay an average price, you will not get the best possible price during the 10 month period, but you also know that you will not be stuck with the worst posisble price.
Of course, if you see a huge dip, you can hedge 20% or 30% that month instead (as long as you can accept the risk that fuel may dip even lower, putting your hedge out of the money if you hedged "on the way down" instad of near the bottom). But I still wouldn't do a 100% hedge just on an apparent dip.
