To help people avoid the problems that Jenny Eckersley encountered here are a few tips. First of all the signs are for Ferney (note the second "e") because that is the French town next to the airport. The only reason for using the French sector even if you are travelling on into France is to pick up a French rental car. In this case follow the "Secteur Francais" signs before passport control (do not go through Swiss passport control) and you will arrive at the French car rental desks. (You will need to ask a baggage handler to go and fetch any checked luggage from the Swiss side.) This does not apply if you are arriving from France as you will be in the French sector to begin with. Or if you aren't renting a French car exit through Switzerland where you will have the full range of transport options including trains to the main station and on to France. If you have rented a French car on leaving the airport follow the signs back to Geneva (it's hardly the airport's fault that the French authorities don't sign their roads very well) and cross back into Switzerland. You will go under the airport runway and link up with the Swiss autoroute that passes in front of the airport. Take this in the direction of Geneva (not Lausanne) and continue on the autotroute until you reach the Bardonnex customs post. From there you will link directly on to the A40. On the way back come off the A40 at Bardonnex and follow the autoroute to the airport. Follow the signs for "secteur francais" to return your car then go to the Swiss side to check in for flights to countries other than France. If in doubt ask the people at the rental desk for directions to your destination. As for walking miles to the B gates there are travellators. You actually have to walk very little at all. Walks to the gates at Heathrow or Gatwick are much more arduous. Geneva is actually one of the most compact best managed airports I have used. It is true that if you want to shop or eat stay landside as long as possible. Airside most of the facilities are in the main terminal so avoid going to the gates until as late as possible. They really are just pre- boarding holding areas (as they are in most airports).
