Transavia offers daily flights between Girona Airport and Paris Orly Airport. Paris Orly Airport is located 14km south of Paris
Paris Orly is much more accessible than Paris Beauvais, as it is only 14km from the centre and has a range of bus and train services on offer. The airport has more airport facilities and services. Transavia flights are reasonably priced and you have a luggage allowance for up to 20kg. The flights are every day in the afternoon, so you should have no problems reaching your final destination.
Transavia´s flights are cheap at face value but the taxes are fairly high, so your final price will not be as cheap as advertised.
