SWA has some room to improve, which should make it relatively easy to regain some savings with little effort or re-training, e.g. CI36 (or 28 for classics) should be reviewed (and most likely lowered). I'd nearly bet those figures are not cost optimal, based on current ops vs. fuel costs.
The planned standard contingency fuel reserves using the following formula for flts between 2~4hrs of :35 is too simplistic (an :45 for those over 4hrs) and has no statistical basis, ie its not relavant to the city-pair. Think about operating a 3hr flt from LAX-SEA (snoozer). And compare that to a 2hr hop from FLA-BWI (white knuckler).
The price of fuel will force overly simplistic procedures and fuel policies to come under further review.
