NAC uses an internal index to calculate the surcharge which will be reviewed and adjusted at least monthly or more often if appropriate. Changes to the surcharge will be effective on the first business day of the week following the noted adjustment which will be posted on this site to allow our customers 24/7 access to the rate. The internal index is primarily based on the average price paid for Jet A in Anchorage which correlates (is not the same but does move up or down) with the weekly average price for West Coast Pipeline Jet A as published in Platt´s Oilgram Price Report.

The surcharge is based on the difference between the current index and the Base Index, established as of November 2004. The Base Index is $1.68 per gallon. A $0.10 per gallon increase in the index results in an increase in the surcharge of 2%. The following table illustrates how changes in the monthly index impact the surcharge:
