How much time should I allow between two flights at CDG?

There's no universal duration. The minimum time depends on your airline, the terminals involved and the flight's status (Schengen or not). Rely on the connecting time shown on your ticket and, if you're changing terminals or arriving from a non-Schengen flight, allow a wider margin.

Is the CDGVAL free and how does it work?

Yes, the CDGVAL is a fully free automated metro that links CDG's three terminals. A train comes roughly every 4 minutes, with an 8-minute end-to-end trip. It runs from 4:00 to 1:00, with a bus taking over at night.

Can I book a room just for a few hours during my layover?

Yes. Day use lets you rent a room during the day for a slot of a few hours, with no overnight stay. Near CDG, Stayflex offers premium hotels in day use (2 to 6 hours) with instant confirmation and free cancellation up to 24 hours before arrival.

Connecting at CDG: how much time between two flights?

You're connecting between two flights at Paris-Charles-de-Gaulle and wondering whether your layover is long enough? There's never a single answer: it depends on your airline, the type of flight and the terminals you have to cross. Here's how to size up your margin with confidence, find your way between the terminals, and turn a long wait into a real break.

There's no universal minimum connecting time

First things first: forget the idea of a single "right" connecting time that works everywhere. Every airport and every airline sets a Minimum Connecting Time (MCT) that varies with the pair of terminals involved, the status of the flight (Schengen or non-Schengen, with passport control) and the type of connection (domestic, international or between different airlines).

As a rough guide only, unofficial travel guides suggest ballpark figures of around 60 minutes for a domestic connection, 90 minutes for an international flight and up to 120 minutes between different airlines. These figures are no substitute for your airline's actual MCT: always check the required time on your ticket or with the carrier. Key point: a single ticket protects your connection according to that MCT, whereas two separately booked tickets offer no guarantee if the first flight is delayed.

Getting between terminals: the CDGVAL

CDG has three terminals: Terminal 1, Terminal 2 (split into modules 2A to 2G) and Terminal 3. Modules 2A to 2F are adjacent and linked by walkways, while 2G is a separate satellite building reached by shuttle bus. Changing terminals therefore takes time, which you need to factor into your calculation.

The good news: the CDGVAL, a free automated metro, links the three terminals, the car parks and the stations. A train comes roughly every 4 minutes and the end-to-end trip (T1 - T3/Roissypôle - T2) takes 8 minutes, so a journey between any two given terminals is shorter. The service runs every day from 4:00 to 1:00, with a replacement bus at night. Even so, allow a comfortable margin for walking, queues and any repeat security check.

Long layover: can you head into Paris?

If your connection lasts several hours, the temptation to reach the city centre is real. The RER B links CDG directly to Paris: allow about 34 minutes to Gare du Nord and 37 minutes to Châtelet-Les Halles, for a ticket of around €14 in 2026 (regulated fare, check on Île-de-France Mobilités before you go).

In practice, a trip out only makes sense with a genuinely long layover. Between the round trip, security checks on the way back and, if your flight is non-Schengen, passport control, you should count on at least 2h30 to 3h of "airport" time. A tour of Paris is only reasonable from around 6 hours of layover. Below that, it's better to stay on the airport side and rest there.

Waiting in peace: a day use room near CDG

Between two flights several hours apart, departure-lounge seats quickly show their limits. Renting a hotel room during the day, without staying overnight, changes everything: that's the principle of day use. You book a room for a few hours at a reduced rate compared with a full night, to sleep, take a shower and set off refreshed.

Stayflex lets you book a premium hotel near Paris-Roissy-Charles-de-Gaulle, whether day use (slots of 2 to 6 hours) or overnight. Instant confirmation, free cancellation up to 24 hours before arrival, secure payment and booking without an account: everything you need to arrange your break with no commitment, even when your travel plans are still uncertain.
