Paris CDG Airport Guide for Americans (2026)
By: Jean-Paul and Jessica - Published May 16, 2025, Updated February 22, 2026
Paris Charles de Gaulle Airport (CDG) is the main international airport serving Paris. It is located in Roissy-en-France, about 23 km (14 miles) northeast of central Paris. CDG has three terminals, nine sub-terminals, and a layout that trips up even frequent visitors. This guide covers everything U.S. travelers need to know before landing, from which terminal your flight uses to how passport control works, how to move between terminals, and what to do before your flight home.
Jessica: "I once missed a connection because I didn't realize I had to go through security again even though I never left the airport. Now I always give myself at least a 2.5-hour layover at CDG. That buffer has saved me more than once."
Which CDG Terminal Do U.S. Flights Use?
Most U.S. flights land at Terminal 2E, including flights on Air France, Delta, and other SkyTeam alliance carriers. Terminal 2E is the most recently renovated terminal at CDG and has the widest selection of restaurants, shops, and lounges.
Here's a quick breakdown of all CDG terminals:
Terminal 2E: Most U.S. and long-haul international flights (Air France, Delta, Korean Air, and other SkyTeam carriers). Three satellite halls (K, L, M) are connected by the LISA internal shuttle.
Terminal 2F: Primarily short-haul and Schengen European flights on Air France.
Terminal 2G: A satellite terminal about 800 meters from the main Terminal 2 complex. Only accessible by free shuttle bus. If your connection routes you here, budget extra time.
Terminals 2A, 2B, 2C, 2D: A mix of international carriers including British Airways, Emirates, American Airlines, and Lufthansa (some Star Alliance and Oneworld flights).
Terminal 1: International carriers outside SkyTeam, including some Star Alliance airlines like United, Lufthansa, and Singapore Airlines.
Terminal 3: Low-cost carriers like easyJet.
Always confirm your terminal with your airline before traveling. Codeshare flights sometimes depart from a different terminal than you'd expect.
Jean-Paul: "Terminal 2E is where most U.S. flights land, especially with Air France and Delta. But if your connection takes you to 2G, plan ahead. It requires a shuttle, and the whole experience feels like arriving at a separate airport."
How to Move Between Terminals at CDG
The free CDGVAL automated train is the main way to travel between CDG's terminals. It connects Terminal 1, Terminal 2 (between sub-terminals 2C/2D and 2E/2F), and Terminal 3 via the Roissypôle area. Trains run daily from 4:00 a.m. to 1:00 a.m., departing every 4 minutes, with a full loop taking about 8 minutes.
Look for signs that say "CDGVAL" or "Correspondance" inside any terminal. Luggage carts are not allowed on board.
Within Terminal 2, sub-terminals 2A through 2F are connected by covered walkways and moving sidewalks. The free N1 shuttle bus also loops between these sub-terminals and the train station. Terminal 2G is the exception: it sits about 800 meters away and is only reachable by the free N2 shuttle bus.
Jessica: "If you're connecting from 2E to 2G, leave at least 20 minutes for the shuttle ride alone. The signage for the 2G shuttle can be easy to miss, so keep your eyes up and ask airport staff if needed."
Passport Control and Security at CDG
All U.S. travelers entering France go through passport control at CDG, whether this is your final destination or you're connecting onward. On layovers, you will also often go through a second round of security screening, especially when connecting between Schengen and non-Schengen flights.
The EU Entry/Exit System (EES): What Americans Need to Know in 2026
Starting in 2026, the EU's new Entry/Exit System (EES) changes how passport control works for all non-EU travelers, including Americans. The system has been rolling out in phases since October 2025, with full implementation across all Schengen borders targeted for April 10, 2026 (though some airports may temporarily ease checks during the busy summer months to manage queues).
Here's what EES means for you at CDG:
First visit under EES: You'll register your biometric data at the border. This means a facial photo and fingerprint scan (four fingers, one hand), taken either at a self-service kiosk or by a border officer. Your name, passport details, and entry date are stored digitally. This first registration takes longer than a traditional passport stamp, so budget extra time.
Future visits: Once registered, you'll just need a quick fingerprint or facial scan to verify your identity. The system stores your data for three years.
No more passport stamps: EES replaces the traditional entry/exit stamps in your passport with a digital record. The system automatically tracks your 90/180-day Schengen stay limit, so there's no ambiguity about how many days you have left.
The "Travel to Europe" app: You can optionally download the EU's official app to pre-register some of your personal data before arriving, which may speed up processing at the border.
During the transition period in spring and summer 2026, expect a patchwork experience. Some border lanes at CDG may use the full EES kiosk process while others still stamp passports manually. Be patient and allow extra time at passport control, especially if you're arriving during peak hours.
Jean-Paul: "This is the biggest change to European border control in decades. The first time through will take longer than you're used to. But once your biometrics are in the system, future trips should actually be faster than the old stamp-in-your-passport routine."
Jessica: "My advice: don't plan a tight connection for your first trip under EES. Give yourself that extra buffer. And have your passport open to the photo page before you reach the front of the line. It always helps."
What about ETIAS? You may have also heard about ETIAS (European Travel Information and Authorization System), which is Europe's version of America's ESTA. ETIAS will eventually require Americans to apply online and pay a small fee (around €20, waived for minors and seniors) before traveling to the Schengen area. ETIAS is expected to launch in late 2026 at the earliest, with a six-month grace period after that. It is not yet required for travel to France, but it's worth keeping on your radar if you're planning trips into 2027. Read our guide on ETIAS here.
PARAFE E-Gates
U.S. citizens 18 and older with biometric passports may be eligible to use the automatic PARAFE e-gates at CDG, which use facial recognition and can cut wait times significantly. Look for them alongside the standard passport queues. Note that as of early 2026, the PARAFE gates at CDG are being updated for full EES compatibility, so availability may vary during the transition. If the e-gates aren't accepting your passport, join the staffed border control line instead.
Jean-Paul: "In France, we value discretion. Stay quiet in line, follow instructions, and don't expect small talk. It's not unfriendliness. It's just how we do things. And if you want to set the right tone for your whole trip, start with a 'Bonjour' when you reach the agent." (More on French phrases that actually help travelers.)
How Much Time to Allow for Connections at CDG
Allow at least 2.5 hours for most connections. If you're changing between distant terminals (such as Terminal 1 to Terminal 2G), or if your onward flight is to a non-Schengen destination, allow 3 hours. That layover window needs to cover walking to the shuttle or CDGVAL, clearing passport control, possibly going through a second security screening, and reaching your departure gate. With the EES rollout in spring/summer 2026, passport control may take longer than usual, especially if it's your first time registering biometrics. Err on the side of more time, not less.
Jean-Paul: "People underestimate CDG. It is not one building. It's a campus spread across kilometers. An hour and a half between flights sounds like plenty until you're standing in a passport line watching the clock."
How Early to Arrive at CDG for Departure
For flights leaving CDG to the U.S. or other non-Schengen destinations, arrive at the airport at least 3 hours before departure. You'll need to check in, clear security screening, and pass through border control (passport check). During peak hours (roughly 7-11 a.m. and 4-9 p.m.), these queues can be long, particularly at Terminal 2E.
For intra-European Schengen flights, 2 hours is generally sufficient.
Jessica: "I know 3 hours sounds like a lot. But at CDG, I've waited 45 minutes just in the passport line before even reaching security. If you end up with extra time, Terminal 2E has plenty of good places to eat and shop."
Traveling Through CDG with Kids
CDG has family-friendly services, though they vary by terminal. Terminal 2E has the best facilities for families.
Strollers are allowed through security and can be gate-checked at the boarding door
Terminal 2E has dedicated baby rooms equipped with cribs, low lighting, feeding chairs, comfortable seating, and microwave ovens for warming bottles or food
Most restrooms across the airport have changing tables
Paul boulangerie, available in most terminals, is a reliable kid-friendly food stop
If you're traveling solo with children, let gate agents or airport staff know. They can often help with boarding and navigating security.
Families with small children and travelers with disabilities can request to move to the front of lines at CDG. This is a common French practice. Make yourself visible to queue staff and they'll usually assist.

Getting from CDG to Paris (Summary)
A lot changed in early 2026. The RoissyBus stopped running permanently on March 1, 2026. The CDG Express train from Gare de l'Est won't open until March 2027. We wrote a full, detailed breakdown of every current option: How to Get from CDG to Paris in 2026 (Every Option, Honestly Ranked)
Here's the summary:
Official Taxi / €56 Right Bank, €65 Left Bank (flat fare, by law) / 45-75 min / Best for most travelers, families, and first-timers.
RER B Train / ~€14 adult, €7 child / 35-45 min / Best for solo travelers with light bags.
Line 9517 Bus (new, replaced RoissyBus) / ~€2-2.55, free with Navigo pass / 50-70 min total / Best for budget travelers who already have a Navigo pass.
Uber or Bolt / Variable pricing / 45-75 min / Best for app-savvy travelers who want door-to-door pickup.
Bus 350 or 351 / ~€2 / 60-80 min / Best for ultra-budget travelers with light luggage.
Jean-Paul: "If it's your first time in Paris and you're jetlagged with luggage, take a taxi. The flat fare means no surprises. Just follow the signs to the official taxi stand at your terminal."
CDG has two RER B stations: "Aéroport Charles de Gaulle 2 - TGV" (between 2C/2D and 2E/2F, convenient for Terminal 2) and "Aéroport Charles de Gaulle 1" (at Roissypôle near Terminal 3, for Terminal 1 arrivals via CDGVAL). The new 9517 bus also departs from Roissypôle.
Food, Wi-Fi, and Amenities at CDG
Free Wi-Fi is available throughout the airport with no time limit and no registration wall. Connect to the "WIFI-AIRPORT" network and accept the terms.
Dining varies by terminal. Terminal 2E has the best variety, including sit-down restaurants and a decent food court near the boarding gates. Across other terminals, Paul boulangerie and Relay convenience shops are reliably available. You can ask any café for free tap water ("une carafe d'eau, s'il vous plaît"). This is standard practice in France.
Power outlets are limited and often occupied, especially in older terminals. Bring a portable power bank. Terminal 2E has more charging stations than the other terminals, including some USB ports near gate seating.
Restrooms are generally clean. Stalls are smaller than what most Americans are used to. Terminal 2E has the best-maintained facilities.
Lounges: If you hold a Priority Pass, American Express Platinum card, or fly business class on a SkyTeam carrier, you can access lounges in Terminal 2E (and some in Terminal 1). Air France's lounges in 2E Hall L are among the best in Europe. If you don't have lounge access, the pay-per-use Yotel in Terminal 2E offers private rest pods and showers for layovers.
Currency exchange desks are in every terminal, but the rates are poor. Use an ATM ("distributeur") instead, which you'll find near the arrivals exits. Most U.S. debit cards work at French ATMs with no issues. Avoid the Travelex and ICE currency counters if you can.
Before Your Flight Home: Departure Tips
Watch your gate. Last-minute gate changes are common at CDG, especially in the large Terminal 2E satellite halls. Check the departure screens frequently in the hour before boarding, and keep an eye on your airline's app notifications.
Download the Paris Aéroport app before you land. It provides terminal maps, real-time flight status updates, gate change notifications via WhatsApp or email, and indoor navigation within terminals.
VAT refunds (Détaxe): If you made qualifying purchases during your trip, head to the Détaxe area before check-in. Lines can be long during peak departure windows, so allow extra time. You'll need your receipts and the completed tax-free forms from the stores where you shopped.
Keep a printed backup. Have your hotel address, flight confirmation, and any transfer booking details printed and stored in your carry-on. Phone batteries die. Apps crash. Paper doesn't.
Jessica: "I keep a printout of my hotel address and flight details in my carry-on every single trip. It's saved me more than once when my phone wasn't cooperating."

Jessica: "And before you know it, you'll be in a taxi crossing the Seine, and none of the airport stuff will matter anymore."
