sorry--forgot you asked about France no need for special branch if going direct to France also no need if going to Guernsey via France not sure how much you need to know about flying in France if its part of the Guernsey rally and you are starting from Guernsey then the organisers will give you all the gen, if you are planning trips to France then we have a new ball game but in no way difficult--happy to pass on more info if needed--cheers
