Aérobus A01
A01 · Aéroport Paris-BeauvaisPickup, hours & luggage
Boards at. Paris Porte Maillot, 22-24 boulevard Pershing — the same stand and ticket desk, open 03:00 to 19:30
EUR 17.90 online, EUR 18.00 at the bus station. A return is EUR 35.00 at the bus station against EUR 29.90 online. A child of 4 to 11 pays EUR 9.90 online but the full EUR 18.00 at the desk, so a family total depends on where you buy.
Luggage. One hold bag and one cabin bag, in the coach hold.
Hours. Every 15 to 30 minutes on average, every day, 03:00 to 19:30 — over four hours earlier than the last coach into Paris. Nothing official leaves Porte Maillot for the airport later than that.
