Thanks, guys, all very helpful gen.The reason to go round the S. via Aix was to keep nearer to the TGV in case of Wx,etc so the pax can continue.I`m sure you know the story- plan on "X" pax, and "X+2", and of course more baggage, will turn up to go -- so, legs get shorter , more refuels, days are shorter ,etc, etc.
27 yrs ago I ferried a couple of Gazelles to Marseille/rtn from a secret Wilts a/f in just under 5 hrs(flying)each way,with 3 stops for customs/ fuel/lunch at Vichy,which had /has? a superb little restaurant. No GPS, only a roll of maps and TANS.
