Online: adult return €29.90, child €19.90. On site: adult return €35.00 and a 4–11-year-old pays the full adult €18/€35 — the child discount simply does not exist at the ticket office.
Even the official shuttle runs from 1h15 to a coach park at Porte Maillot on the western ring road, and the A04 La Villette line from 1h30. With a metro hop to your hotel, budget 1h45–2h30 after landing — guides that treat BVA as a Paris airport are setting you up.
Several domains brand themselves 'Official Distributor' of the Beauvais shuttle, and a taxi site calls itself the 'official taxi of Beauvais Airport' — the airport's FAQ is blunt that tickets are sold only on aeroportparisbeauvais.com, aerobus.fr, or at the two staffed ticket offices. Never from drivers.
France resets its Paris airport flat fares yearly (2026: CDG €56/€65, Orly €45/€36 per the arrêté of 24 December 2025) and Beauvais is deliberately outside them. A tout quoting a 'regulated flat price' to Paris is inventing it; the airport's own table says ~€185 day / ~€230 night.
The last Beauvais→Paris Nord departure is listed around 20:10, and you still need €1 bus or €17–21 taxi time to reach the station 6.5 km away. A 21:30 landing that 'could' have gone by TER at €8 instead of a €230 cab quietly cannot.
