Orly is south of Paris and Lille is to the north: the whole challenge is crossing the Île-de-France region efficiently. Depending on the time, we take the A86 east of Paris or the Francilienne, then join the A1 near Roissy.
Once on the A1, it is straightforward: Picardy, the Somme, Artois, and Lille about an hour and a half later.
By public transport, the same trip means getting into Paris on metro line 14 or the Orlyval, crossing the city to Gare du Nord, then taking a TGV. With children or several suitcases, a car with driver has no real competition.
Your chauffeur tracks your flight, waits for you in the arrivals hall of your terminal and walks you to the vehicle. You arrive directly in Lille, Roubaix, Tourcoing or across the Belgian border.
