Here's a month-by-month look at prices on this route:
✈️ Which airlines fly from Chicago to Paris?
Four carriers serve ORD-CDG: three nonstop (United, American, Air France) and one value one-stop (Icelandair via Reykjavik). Air France flies the route most often - 21 weekly departures on its A350-900 - while United and American each run daily 787 service. Icelandair undercuts all three by $80-260 round trip if you can spare 2-4 extra hours for a free Iceland stopover.
United's 787-10 is the low-drama nonstop choice. It departs Terminal 1 Concourse C daily, next to the Polaris Lounge, and lands at CDG Terminal 2E in roughly 8 hours. Economy Plus adds 5 inches of pitch for $80-150 each way - worth it overnight. Skip Basic Economy if you're checking a bag; it blocks seat selection and boarding priority. Redemptions run 120,000-160,000 MileagePlus miles round trip in business.
Best for: MileagePlus members and Chase Sapphire cardholders chasing Polaris upgrades
Air France is the comfort pick, not the cheap one. Its A350-900 flies from ORD Terminal 5 up to three times daily - 21 departures a week, more than United and American combined - landing directly at CDG Terminal 2E, one walk from RER B and TGV connections. Complimentary wine and a full hot meal beat both US carriers' catering. Expect $40-100 more than United or American for the same dates.
Best for: comfort-focused travelers and same-airline CDG connections onward
American's 787-8 nonstop is usually the cheapest of the three full-service carriers, often $10-40 below United on the same date. It departs ORD Terminal 3 - a longer walk from security than United's Terminal 1 - and arrives CDG Terminal 2E alongside fellow oneworld member British Airways. Basic Economy blocks free seat selection and charges extra for checked bags; skip it on an overnight leg where seat choice matters.
Best for: AAdvantage elites and Citi/Barclays cardholders
Icelandair is the route's real value play - $80-260 cheaper round trip than any nonstop, with a free Reykjavik stopover for up to 7 nights at no extra airfare. The tradeoff: a 1.5-3 hour KEF layover each way adds 2-4 hours total versus flying nonstop. Basic fares are carry-on only, so budget $65+ each way for a checked bag on longer trips.
Best for: budget travelers who can add a free Iceland stopover
Mubboo verdict: United's daily 787-10 is the safest nonstop pick, Air France wins on cabin comfort and frequency, and Icelandair's free Reykjavik stopover beats both on price for flexible travelers.

Compare all flights →📅 When should you book Chicago to Paris flights?
Book ORD-CDG economy 5-7 weeks before departure for the lowest fares on all four carriers - prices spike inside the 21-day window, especially in June and July. Tuesday and Wednesday departures run $60-150 cheaper than Friday or Sunday on United, American, and Air France. February and November are the two cheapest months to fly, both dipping near $505-560 round trip. Icelandair's fares move independently of the nonstop carriers and sometimes undercut them by over 20% even inside the 30-day window. Avoid the week of Thanksgiving or the two weeks around Christmas unless you've already checked November 1-15 or early January, when fares drop sharply after the holiday rush.
The most expensive month to fly - 77F highs, the year's heaviest rain at 5.6in, and peak-summer demand from every direction.
If you're a family flying in summer, book by March — peak season fills up fast.
Budget travelers: shoulder season (Sep–Oct, Apr–May) offers the best balance of price and weather.
💡 This Jul: Fly the first or last week of July, not the middle, to save $100-200.
🏙️ Why visit Paris?
Paris earns its reputation as a global hub for art, fashion, and food - the Louvre alone holds enough to fill three days, and neighborhoods like Le Marais and Montmartre reward aimless wandering more than any checklist. The romantic, walkable core means most first-timer priorities - the Eiffel Tower, Notre-Dame, Seine river walks - sit within a few Metro stops of each other. Safety is generally good, though pickpocketing around major sights and on crowded transit is common enough that the US State Department flags it specifically; keep valuables zipped and skip anyone offering a 'free' bracelet near landmarks. Parisians respond well to a simple 'Bonjour' on entering any shop - a small courtesy that visibly changes how you're treated.
What makes Paris worth the flight:
Beyond the landmarks, Paris rewards specific bookings: skip-the-line Louvre tours run $73-427 depending on group size, a 10-tasting Le Marais food tour runs about $270, and a guided Montmartre walking tour is $35. Recent visitors rate the Louvre's six-guest evening tours as the best way to see the Mona Lisa without a crowd blocking the view.
Best neighborhoods to explore:
Cobblestone lanes packed with falafel stands and vintage shops, plus a 10-tasting food tour ($270) locals rate among the city's best.
Home to the bohemian streets where Picasso and Van Gogh once lived; a guided walking tour runs about $35.
Student-priced cafes and bookshops within a 10-minute walk of Notre-Dame Cathedral and the Seine.
Historic literary cafes and wine bars dense enough for a full evening crawl without leaving a few blocks.
Don't miss:
Eiffel Tower
Paris's defining landmark; book summit tickets online to skip a 60-90 minute walk-up line.
Browse Eiffel Tower tours →The Louvre
Guided tours run $73-427; the 6-guest evening tour beats seeing the Mona Lisa through a crowd.
Browse The Louvre tours →Notre-Dame Cathedral
Reopened after its post-fire restoration; free to enter, a 10-minute walk from the Latin Quarter.
Browse Notre-Dame Cathedral tours →Montmartre & Sacre-Coeur
Hilltop basilica and artist quarter; a guided walking tour runs about $35 and covers both in 2 hours.
Browse Montmartre & Sacre-Coeur tours →Le Marais food tour
A 10-stop tasting tour (~$270) through croissants, cheese, and a classic croque-monsieur stop.
Browse Le Marais food tour tours →Seine River cruise
An hour on the water puts Notre-Dame, the Louvre, and the Eiffel Tower in one sightline after dark.
Browse Seine River cruise tours →Mubboo Verdict:
Paris rewards a first visit built around walking, not a rigid itinerary - book the Louvre and one guided food tour in advance, then let Le Marais and Montmartre fill the rest.

🧳 What do you need to know before flying to Paris?
🛂 Do Americans need a visa for Paris?
US passport holders travel to France visa-free for stays under 90 days [GOV: travel.state.gov]. That changes starting Q4 2026, when the EU's ETIAS pre-travel authorization becomes required - a $20 fee, valid three years, applied online before you fly. Check current requirements at travel.state.gov before booking a trip landing after the rollout.
🕐 What's the time difference?
Paris runs on Central European Time, 7 hours ahead of Chicago year-round (CET/CEST vs. CST/CDT). Europe and the US shift clocks on different March/November weekends, so the gap briefly narrows to 6 hours for about a week each way.
🚇 How do you get from the airport to the city?
CDG to central Paris: about 23 miles (37 km) northeast, 35-70 minutes depending on option.
| Option | Time | Cost | Best for |
|---|---|---|---|
| RER B train (editor's pick) | 35-45 min | ~$12 | Solo travelers, light luggage |
| Fixed-rate taxi | 45-70 min | $56 (Right Bank) / $65 (Left Bank) | Groups, heavy luggage, late arrivals |
| Private transfer | 45-70 min | $65-90 | Families, pre-booked door-to-door |
| Express bus 9517 | 50-60 min | ~$16 | Saint-Denis Pleyel-area hotels |
Editor's pick: RER B - cheapest and fastest for anyone without heavy luggage, running every 10-15 minutes from CDG Terminal 2E.
💷 What about money and tipping?
1 USD is about 0.88 EUR as of 2026-07-01T17:42:42.312Z - check current rates before you go, since they shift week to week. ATMs are widely available across Paris; tipping 5-10% at restaurants is customary but not expected the way it is in the US.

📱 Will your phone work?
France's country code is +33; a US phone typically needs an eSIM or local SIM to avoid roaming fees, since most US carrier international plans charge per-day or per-MB premiums. Dial 00 before a US number when calling home from a French landline.

💡 Insider tips: Chicago to Paris
Book Tuesday or Wednesday, not FridayMubboo original data
Same-route fares swing $60-150 by day of week. United, American, and Air France all price Friday and Sunday departures highest, chasing weekend leisure demand. Our review of fare patterns across all four ORD-CDG carriers found Tuesday and Wednesday departures consistently priced lowest, even during the June-August peak.
The Roissybus is gone - use RER B instead
Paris retired the Roissybus airport shuttle on March 1, 2026. If a guidebook mentions it, ignore that. The RER B train now covers CDG-to-city in 35-45 minutes for about $12, running every 10-15 minutes from Terminal 2E's platform - cheaper than the discontinued bus ever was.
Icelandair's stopover turns one flight into two trips
Icelandair lets you break your Chicago-Paris ticket in Reykjavik for up to 7 nights at no extra airfare. Add a few days in Iceland for the price of one nonstop ticket to France. The only cost is time: expect 2-4 extra hours of total travel versus flying United or Air France direct.
ETIAS adds $20 and a form starting Q4 2026
The EU's ETIAS travel authorization launches in Q4 2026 and becomes mandatory around April 2027, ending true visa-free entry for US passport holders. If your trip lands after the rollout, apply online before booking - a $20 fee, valid three years, similar to the US's own ESTA. Trips booked for 2026 travel dates are unaffected.
ORD's terminal split can blindside same-day connectionsMubboo original data
United departs international flights from Terminal 1, but all international arrivals - including your own return flight from Paris - land at Terminal 5. Travelers connecting onward from a domestic United flight sometimes assume a same-terminal connection; it isn't one. Our review of ORD's layout found this catches even experienced United flyers off guard on both legs.
👥 Who flies this route — and what they should know
Family of four visiting Disneyland Paris
Featured this monthFly American or United's evening nonstop and land at CDG in the late morning, giving jet-lagged kids a full day to adjust before an early Disneyland Paris start the next morning. Both airlines allow a free checked bag per traveler outside Basic Economy - worth the $30-50 upcharge for four sets of luggage. RER B runs directly from CDG to Marne-la-Vallee-Chessy, Disneyland's own stop, without a transfer through central Paris. Mubboo Pick: United or American main cabin, RER B direct to the park, skip a Paris hotel the first night. Avoid the July-August fare spike - March, April, and late September deliver similar crowds at $200-300 less per ticket.
First-time Paris tourist from Chicago
Fly Air France's evening nonstop and land at CDG Terminal 2E already rested - its A350-900 cabin edges out United's and American's for an overnight flight. Clear immigration, then take the RER B (about $12, 35-45 minutes) into central Paris rather than a pricier taxi on your first trip. Base yourself in Le Marais or the Latin Quarter - both walkable to the Louvre, Notre-Dame, and Seine river paths. Mubboo Pick: Air France, window seat, RER B into the city. Skip renting a car; the Metro and RER cover everything a first-timer needs. Book your Louvre entry timed-ticket before you land - lines run 45-90 minutes without one. Visit April-May or September-October for milder weather and shorter lines than peak summer.
Budget backpacker chasing the Iceland stopover
Book Icelandair and add the free Reykjavik stopover - up to 7 nights in Iceland cost zero extra airfare, just lodging you'd pay for anywhere. Basic fares run $430-780 round trip, $80-260 below any nonstop carrier, but they're carry-on only - pack light or budget $65+ each way for a bag. The ORD-KEF leg runs about 6 hours, then KEF-CDG adds roughly 4h 10m with a 1.5-3 hour layover. Mubboo Pick: Icelandair Basic Economy, carry-on packing, a 3-4 night Iceland stopover on the way home. Skip peak July departures if budget is the priority - Icelandair's fares climb along with everyone else's in summer. February and November stopover bookings run cheapest.
Points-and-miles business traveler
Fly United's daily 787-10 and redeem MileagePlus miles for Polaris business - typically 120,000-160,000 miles round trip, with the Terminal 1 Polaris Lounge for a pre-flight shower and meal. American's AAdvantage program prices similarly if oneworld award space opens on the AA150 nonstop. Air France's Flying Blue often has the softest business award space of the three, especially booked 3+ weeks out. Mubboo Pick: United Polaris on points, Air France Flying Blue as backup search. Skip peak-season cash business fares, which run $3,500-5,500 round trip in June-August - redeem miles instead. Chase Sapphire Reserve and Amex Membership Rewards both transfer directly to Flying Blue and MileagePlus.
Solo food-and-wine traveler
Fly Air France for the onboard wine service and land already in the mood for Le Marais's food scene - the neighborhood's guided tastings (around $270 for a 10-stop tour) pair naturally with a Flying Blue mileage run. Base yourself in Le Marais or Saint-Germain-des-Pres, both dense with wine bars and markets within walking distance. Mubboo Pick: Air France solo, Le Marais lodging, book the food tour before landing since weekend slots fill fast. Skip a rental car entirely - Paris's dining neighborhoods are built for walking, not driving. Shoulder-season trips (March-May, September-October) mean easier restaurant reservations than peak summer. Reserve dinner tables 2-3 weeks ahead for anything with a Michelin mention.
Thanksgiving-week getaway couple
Fly out the Tuesday or Wednesday before Thanksgiving, not the holiday weekend itself - November fares average $560 round trip, among the cheapest of the year, but only outside the actual Thanksgiving travel window. United, American, and Air France all add extra frequencies that week, so seat availability isn't the constraint - price is. Mubboo Pick: book by early October for November dates, and return the following Tuesday to avoid the Sunday-after-Thanksgiving crush at CDG. Skip Icelandair this specific week; its smaller ORD-KEF aircraft sells out faster than the three nonstop carriers during the holiday surge. Paris in late November runs cool and quiet - fewer tourists, shorter museum lines.
⚖️ Flight delayed or canceled?
EU261 covers delays and cancellations of 3+ hours on Air France and Icelandair's KEF-CDG leg, and on the CDG-departing return flights of all four carriers - up to 600 EUR per passenger. Outbound flights departing the US aren't covered by EU261, only by each airline's own contract of carriage.
Flight delayed or cancelled? You may be owed up to €600 in compensation.
📱
Free option: Free option: most French cafes, the Metro, and your hotel offer free Wi-Fi if you're only checking messages.
Skip roaming fees with a prepaid France or EU-wide eSIM - most plans cover 30 days of data for $8-25, installed before you land.
🛡️
Free option: Free option: check whether your credit card already includes trip delay or baggage coverage before buying a separate policy.
An 8-10 hour transatlantic nonstop is exactly the kind of trip travel insurance is built for - trip delay, lost bag, and medical coverage typically run $40-90 for a one-week France trip.
🚗
Free option: Free option: the RER B train covers the same trip for about $12 in 35-45 minutes if you're traveling light.
A private transfer from CDG runs about the same $65-90 as the fixed-rate taxi, but you book and pay before you land - no queue, no surprise fare.
Emergency contacts in Paris
Frequently asked questions about Chicago to Paris flights
Yes - three airlines fly nonstop. United, American, and Air France operate near-daily nonstop service between O'Hare (ORD) and Charles de Gaulle (CDG), taking about 8h 05m-8h 15m eastbound and 10h 15m-10h 25m returning against the jet stream.
Icelandair offers a fourth, cheaper one-stop option through Reykjavik if you're open to a longer trip with a free Iceland stopover built in.
