We are EA members, and when leaving the aisle with our Dodge Intrepid this last trip, the attendant asked us if we wanted the option to have the gas filled when we returned for $1.40 a gallon. We agreed, thinking this was an okay price, and would save us time refilling on the way back. When we received our little printout bill when we returned, I noticed that it was much higher than my reservation. Checking it further on the plane, I saw that they charged us $24.80 for FSO, or Fuel Service Option. We had only used a quarter of a tank of gas! It would have cost us no more that $5 or $6 to refill it ourselves. I called customer service when we got home, and they explained that the FSO is a set charge, whether you use a full tank, or nothing at all. I told them that this was not how it was explained to me at checkout on the aisle, so they credited my credit card for the amount. Now I'll stick to refilling the tank ourselves, like we had in the past. If you use this option, then make sure you do alot of driving around, and use up the whole tank of gas!!
