New York → Paris (JFK–CDG): the numbers-first briefing

This is the transatlantic route people fly on autopilot, which is exactly why it rewards a few minutes of planning. Here is the short version, in numbers, followed by what to do with them.

The numbers

• 5,834 km (3,625 mi) — great-circle distance between JFK and CDG, computed from our airport coordinates.
• ~7h18 — what our JFK–CDG route page estimates at a flat 800 km/h. It is a floor, not a schedule.
• 7h40 — scheduled gate-to-gate for Air France AF7, departing JFK 21:30 and arriving CDG 11:10 the next morning, per FlightStats. Delta’s evening DL264 is scheduled at roughly 7h35–7h45 depending on the season.
• 8h15–8h30 — the same trip westbound. AF8 is scheduled at 8h15 (CDG 16:30 → JFK 18:45), and Delta’s DL265 at 8h30 in September.
• 6 hours — Paris is six hours ahead of New York for most of the year.
• ~11 — daily non-stops from JFK to CDG at the time of writing, across Air France, Delta, American and JetBlue, according to FlightsFrom’s schedule data. Air France runs most of them. (Our route page lists the historical OpenFlights snapshot, which includes carriers that have since left the route.)

The east–west gap is not an airline quirk. Eastbound flights ride the jet stream, the band of strong westerly winds at cruising altitude; westbound flights fight it, which is why the trip home is scheduled 35–50 minutes longer. Winter jet streams are typically stronger, so the gap tends to widen then — check the schedule for your date rather than assuming.

Jet lag plan

Eastbound over six time zones is the harder direction for most bodies, because you have to fall asleep earlier than your internal clock wants. The CDC Yellow Book recommends a few things that genuinely work on this route:

1. Shift early. For two or three days before you fly, move bedtime about an hour earlier each night. Even a partial shift makes the first Paris morning easier.
2. Pick the late departure and sleep. The 21:30–23:30 departures land mid-morning to midday. Eat before boarding, skip the full dinner service, and treat the flight as a short night.
3. Chase morning light. In Paris, get bright daylight in the morning and avoid bright light late in the evening for the first couple of days. A walk along the Seine at 11:00 does more than a third coffee.
4. Melatonin, if you use it, works best taken around 90 minutes before your target bedtime in Paris, according to the CDC’s guidance. Ask a clinician if you are on other medication.
5. Don’t nap long on day one. Twenty minutes, alarm set. Then stay up until at least 22:00 local.

One timing quirk: Europe’s clocks go back on 25 October 2026 and the US’s on 1 November, so for one week the gap is five hours, not six. If you have meetings that week, double-check invitations.

Arriving at CDG

At the border. The EU’s Entry/Exit System (EES) has been fully operational since 10 April 2026. If you are a non-EU visitor, your first entry under EES involves having your face photographed and fingerprints scanned; after that, it replaces passport stamps. Budget extra time on the first trip. US citizens can visit the Schengen area visa-free for up to 90 days in any 180-day period — the US State Department’s France page has the current details.

About ETIAS. You will see lots of websites selling “ETIAS applications”. As of late September 2026, the European Commission says ETIAS is “currently not in operation and no applications for travel authorisations are collected”, and that the EU will announce the start date several months in advance. Earlier EU statements pointed to the last quarter of 2026, but no firm date had been published at the time of writing. Don’t pay anyone for an ETIAS now; when it launches, the official route will be through the EU’s own travel-europe.europa.eu site.

Getting into Paris. RER B runs from the CDG terminals to Gare du Nord, Châtelet and the Left Bank, and the Roissybus runs to Opéra. Under the fare structure introduced in 2025, a single airport ticket valid on Métro, RER and Transilien costs €14 for adults at the time of writing — more than a standard ticket, so don’t buy the cheaper one and hope. Taxis to central Paris run on regulated flat fares (different for the Right Bank and Left Bank); use the official rank, not anyone who approaches you inside the terminal.

Terminals. Air France and Delta use Terminal 2 at CDG (AF8 to JFK, for example, boards in 2E). At JFK, Air France has announced it will move all its flights into the New Terminal One starting next year, so check your terminal on the day for 2027 trips. Our CDG airport page has the layout.

Money and power

Currency. France uses the euro. Contactless card payment is standard almost everywhere in Paris, including on the Métro gates. A card with no foreign transaction fee is the single best money decision on this trip; our currency page shows the live USD–EUR rate.

Plugs. France uses Type C and Type E plugs at 230 V, 50 Hz. US plugs won’t fit, so bring an adaptor. Most phone and laptop chargers are rated 100–240 V and only need the adaptor; check the small print on anything with a heating element (hair tools, travel kettles), which may need a converter or should just stay home.

Data. An eSIM set up before you leave means maps and ride apps work the moment you land. Airalo Partner sells France and Europe-wide plans.

Q&A with yourself

“Is the cheapest fare worth it?” Compare total cost, not the headline. Basic fares may exclude a checked bag or seat selection. KAYAK Partner is useful for seeing all four carriers side by side before you book direct.

“Morning or evening departure?” If you can sleep sitting up, the evening flights give you a full first day. If you can’t, consider the rare daytime option or accept that day one is a write-off and book something low-stakes.

“Do I need to do anything for ETIAS or EES before I go?” Not for ETIAS — it isn’t running. For EES, nothing in advance; just allow extra time at the border on your first entry.

“How early should I get to JFK?” Earlier than you think for a Friday or Sunday evening flight. Van Wyck traffic is less predictable than the flight.

“What about the trip home?” Plan for the longer westbound block and a late-afternoon New York arrival. Westbound jet lag is gentler: stay up until a normal local bedtime and you’ll be mostly back on schedule within a couple of days.
