Taxis are available at every terminal with fixed fares to Paris, while ride-share services (VTC) can also be booked on arrival. Several bus routes, including the 9517 line to Saint-Denis Pleyel station, serve the Île-de-France region, and shuttles connect to other airports or Disneyland Paris. Car rentals and parking are available if you prefer to drive, with the airport accessible via the A1 and A3 highways. The planned CDG Express rail link, expected to open in 2027, will offer a 20-minute non-stop ride to Gare de l'Est.", "toolsUsed": [], "references": [{"url": "https://parisaeroport.fr/en/passengers/charles-de-gaulle-airport", "title": "Welcome to Charles-de-Gaulle airport (CDG Airport) - Paris Aéroport", "time_published": "2026-03-25T23:16:15Z"}, {"url": "https://parisaeroport.fr/en/charles-de-gaulle-airport/terminal-3", "title": "Maps & Terminals at Paris Charles de Gaulle – Paris Aéroport", "time_published": "2026-03-25T23:15:25Z"}, {"url": "https://en.wikipedia.org/wiki/CDG%20Express", "title": "CDG Express", "time_published": "2026-01-29T07:39:10Z"}, {"url": "https://en.wikipedia.org/wiki/Aéroport_Charles_de_Gaulle_2_TGV_station", "title": "Aéroport Charles de Gaulle 2 TGV station", "time_published": "2026-04-23T11:27:05Z"}, {"url": "https://www.parisaeroport.fr/en/group/strategy/airport-network/paris-charles-de-gaulle-airport", "title": "Pardon Our Interruption"}]}, "q4": {"question": "When is the cheapest time to fly from Baltimore to Paris?", "answer": "The cheapest months to fly from Baltimore to Paris are October, November, and September, with average fares around $692, $719, and $785 respectively. The most expensive months are June, May, and March, where average prices climb to $1,375, $1,201, and $1,196.", "methodology": "This 'good deal' estimate shows a representative best price for each departure date across roughly a 12-month window (about 3 months back and 9 months forward). It is built from real flight prices found by Priceline users searching this route, accumulated into a price history for each departure date. Rather than weighting all of that history equally, we apply exponential time decay so recent prices dominate — a price seen yesterday counts almost in full, one from about a month ago roughly a third, and prices from a few months back very little — giving a figure that tracks today's market instead of a stale long-run average. Clear price outliers are removed before any calculation, departure dates with no observations are filled in from nearby dates, and the resulting curve is lightly smoothed so it reads as a clean seasonal trend rather than day-to-day noise.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from Baltimore to Paris?", "answer": "For the best fare from Baltimore to Paris, aim to book 10 to 13 weeks before departure, when prices average around $919. Booking too late can push costs above $1,700, while booking too early may also see slightly higher fares. Around summer and holidays, demand spikes tend to shift the ideal window a bit earlier—adding a few extra weeks can help lock in a better deal.", "methodology": "This booking-window guidance is built from the same real flight prices found by Priceline users searching this route, re-grouped by how many days before departure each price was seen (from the departure day out to about 180 days ahead) across the route's price history. At each booking lead time we report the 25th-percentile price — the cheaper end of what travelers were quoted, rather than the rock-bottom minimum (which can be a fluke) or the average (which is pulled up by expensive last-minute fares). The buy-or-wait advice then applies a risk premium that grows as departure approaches, since seat availability shrinks and prices become less predictable; using that adjusted curve we flag windows where waiting is likely to save a meaningful amount (at least $20 or 5%) versus windows where booking now is the better call. Isolated single-day recommendations are filtered out, so the advice only reflects a window that holds for several days in a row.", "toolsUsed": ["booking_timing"]}, "q6": {"question": "Are overnight (red‑eye) flights available from Baltimore to Paris?", "answer": "No nonstop red‑eye flights operate from Baltimore to Paris, but connecting itineraries whose long leg is an overnight flight are available.

The MTA Light Rail also connects the city center to the airport in roughly 40–45 minutes. Taxis and ride‑share services take about 20–30 minutes depending on traffic and are more expensive than rail.
