Always check contract fuel (CAA, UVAir, AvFuel, Mariah, JFI, etc) and call the FBO directly if there isn't any contract fuel listed.

I've found AirNav, Fltplan, and most every other website else is highly unreliable when it comes to accurate, current information.

Besides, you should call to ask about ramp/facility fees anyway and talking to somebody on the phone is an easy way to start negotiating fuel price & uplift amounts...
