France remains a pretty devopping country in terms of Airline-competition and free access to air-servces.
Air France will do anything to kill competition ( historically proven - Ait Lib was killed from inside by an AF mole planted in the company..)
Cities like Toulouse,Montpellier,Lille or Starsbourg have very little competition and customers have the choice to fly either AF via Paris or take the TGV ( which is good into Paris but takes the better part of a day for trips east to west or north-west to south -east......)
Ryanair does fly from many province-airports to the UK ,but if I want to go from Montpellier to Madrid ,Lisbon or Rome- it still cost me a trip via Paris - which is completely stupid . !
There is lots of room for business in France and I think sooner or later the sky's will see a lot of UK registered planes taking off...
( I live in the south of France and find the AF monopoly disgraceful !!!!!)
