Chicago Paris

O'Hare has four terminals: Terminal 1, Terminal 2, Terminal 3, and the international Terminal 5. There is no Terminal 4. The terminals spread across a wide footprint connected by the ATS train and underground walkways. Allow 15 to 20 minutes to move between them.

Terminal 5 sits apart from the domestic terminals and handles most international flights. The ATS train connects it to the rest of the airport. Afternoon peaks bring longer security and immigration lines. The terminal is functional and recently updated, but smaller than the domestic concourses.

Terminals 1, 2, and 3 form the domestic core, with more dining and lounge options. The Blue Line train to downtown stops under Terminal 2, accessible from any terminal via the ATS.

Charles de Gaulle is three airports wearing one name. Terminal 1 is the original 1974 brutalist circle with satellite gates reached through underground tunnels. It handles Star Alliance carriers and has a retro-futurist quality that either fascinates or confuses on first visit. Terminal 2 sprawls across sub-terminals labeled 2A through 2G, the largest section by far, with 2E handling most transatlantic arrivals. Terminal 3 is the budget terminal: basic, separate, and a different experience entirely.

The CDGVAL automated shuttle connects the three terminals in about 8 minutes, but the walk from your gate to the shuttle platform can add another 10. Walking between Terminal 1 and Terminal 2 is not realistic without the shuttle. Within Terminal 2, some sub-terminal connections are walkable and others require a bus. Security wait times spike during the morning transatlantic departure push from 2E.

The defining fact about CDG is its distance: 25 kilometers northeast of central Paris. The airport itself is well-equipped, modern in the newer sections, and stocked with restaurants and shops. But everything about your trip includes that commute into the city, which takes longer than many short-haul European flights.

Beauvais-Tillé is a single-terminal airport 55 miles north of Paris. The distance from the city makes it a budget carrier outpost rather than a true Paris airport. Facilities are minimal: a few cafés, limited seating, and no transit rail link. Expect long queues at peak hours in a building not designed for the volume it sometimes handles.

No jet bridges at most gates. You walk across the tarmac to your aircraft. Check-in counters and security share the same compact space. If your flight is delayed, there is not much to do inside.

Orly is compact, close to the city, and often overlooked by transatlantic passengers who default to CDG. Four terminals numbered 1 through 4 handle a mix of domestic, European, and a handful of long-haul flights. The terminals connect to each other on foot, no shuttle trains or underground tunnels required, which is a genuine relief if you have ever navigated CDG.

The international arrival areas are smaller and immigration moves faster than at CDG. The terminal buildings are functional rather than architecturally ambitious, though recent renovation has added polish to the arrivals hall and retail areas. It lacks the scale and lounge options of CDG, but what it trades in size it gains in speed.

Orly sits 13 kilometers south of central Paris. For anyone staying on the Left Bank or in the southern arrondissements, the ground transfer advantage over CDG is significant: half the distance, half the cost, and less time stuck on the motorway. The airport operates under an overnight curfew, so late-night departures and early-morning arrivals are not an option.

Châlons Vatry sits about 90 miles east of Paris in the Champagne countryside. It is a Paris airport in name only. The facility started as a military airfield and handles very little scheduled passenger traffic. A single small terminal covers check-in, security, and boarding in a space that feels closer to a regional bus station than an airport.

If this airport appears in search results for Paris flights, check the ground transport situation before booking. Getting to central Paris takes over two hours by road, and there is no rail connection from the airport.
