I know from talking to the aeroclub that manages the fuel station that LFPT received a truckload of 100LL yesterday. Avgas was NOTAMed unavailable during the transfer operation.
Beyond that I do not know what the situation is at other airfields, but today it seemed like many petrol stations received deliveries and the long queues in front of every open station have miraculously disappeared. Newscasts claim that the blockages at all refineries were resolved.
Colin, can I ask you what your preferred routing into Cannes is?
