Whitetracks Helicopters provide a very slick service through airports...
Please note: without prior and special permission French helicopters are not allowed to fly other countries internal flights i.e. Swiss airports to Swiss ski resorts, this also applies vice versa Swiss helicopters are not allowed to fly internal French flights. However, they are allowed to fly from one country to another. A prime example of this would be Geneva Contrin International airport (Genf) in Switzerland, which is a major gateway not only to the Swiss Alps but also to the French Alps.
Examples of country to country flights would include; Geneva airport to Megeve, Swiss airport to French ski resort or Megeve to St Moritz - French ski resort to Swiss ski resort. When a helicopter crosses country borders it may be necessary for the helicopter to briefly stop somewhere for customs on the way to the final destination.
