Aviation fuel prices are subject to more security than Heathrow Airport when the Sky News team are prowling around! They are not published as all operators pay differing amounts, based on their usage and bargaining power. However base prices can be obtained by a bit of snooping and from this I can tell you a certain Scottish airport was charging 32.5p per litre last week as against 34.5p in November. Others will require a bit more work to obtain.
