Buy the EUR 14 airport ticket, not the EUR 2.55 one. The ordinary Métro-Train-RER ticket and the Navigo Jour are sold everywhere and are not valid to or from the airport; the machines at the airport sell the right one.

The EUR 14 ticket is void on every bus, including the night bus. If you land after the last train, the N143 needs a separate EUR 2.05 Bus-Tram ticket.

Two trains, two speeds: trains with two intermediate stops reach Gare du Nord in 31 minutes, all-stations trains in 35 to 40. Both cost the same; take whichever comes.

On most weekday evenings this autumn the last train from the airport is 22:49, not 23:50, and the replacement bus takes 80 to 90 minutes to Gare de l'Est from the Roissypôle bus station, not from the platforms. Check the day before relying on a late train.

A Navigo Easy card cannot hold an airport ticket and a Métro-Train-RER ticket at the same time. If yours already has ordinary tickets on it, buy the airport ticket on your phone or on a second card.

Two children aged 4 to 9 travel for the price of one adult; under 4 is free. There is no family or group price beyond that.

From five people the taxi is cheapest to the right bank: EUR 61.50 against EUR 70 on the RER B, EUR 78 for eight against EUR 112. An ordinary taxi seats four, so book a larger one for five or more; the booking fee still leaves it ahead.

To the left bank (EUR 65 flat), five people pay EUR 70.50 by taxi against EUR 70 by train — the taxi wins from six. The boundary is the river: 1st–4th, 8th–12th and 16th–20th arrondissements are right bank; 5th–7th and 13th–15th are left.

It is the same price at 03:00 as at noon. The arrêté has no night, Sunday or holiday variant for the flat fare, whatever the meter's tariff letter says.

Ask for a stop or a detour on the way and the flat fare no longer applies; the meter does. Waiting you request is charged on top.

No authority publishes a taxi journey time; 45 minutes is a working estimate, based on the N143 night bus's 42-minute timetabled run on the same road with no traffic. Allow more than an hour at peak.

Any Paris taxi must apply this fare, and the ranks are the place to find one. A driver quoting more than EUR 56 to a right-bank address for four people with bags is wrong.
