Transfer Time Between Flights at CDG

If it were me, I'd take the 1 PM. If you book the 9:55 AM you have just over 2 hours to change, which might be possible but only if your incoming flight is right on time.

always dangerous to book a follow on on a separate ticket; definitely 1 pm. two hours is not enough; you only make it if everything goes better than it often does. Immigration easily takes an hour, check in and security easily takes an hour. check in often closes well before scheduled departure time. Go for 1 pm and plan to have a leisurely lunch at the airport.

If you haven't purchased your ticket yet, I would encourage you to consider flying on a single ticket to save yourself a lot of time and hassle.

If you have a preference for American/British Airlines/One World, you can fly BOS to LHR to Marseille (bypassing CDG). I'm a Delta guy, so I would fly Delta/Air France from BOS to CDG and then on to Marseille.

Check airline websites frequently for fare sales. On June 1 last year, I snagged a ticket for October travel to France for $824 (had been $1800; open jaw to Rennes with return flight from CDG). This year I'm headed to Switzerland in October; I got up one recent Saturday morning and started randomly putting routes into the Delta website. I found a round trip ticket to Zurich for $667.

A friend and I pulled off what you are proposing rather easily at the Munich airport with a 3-hour layover, arriving on Delta and then catching a Lufthansa flight to Vienna (also doing this in reverse when returning to the US), but (1) we had no checked luggage and (2) the Munich airport is easier to navigate than CDG.

Thank you for your insights and recommendations! We'll plan for the later flight.

If you have not booked your tickets yet, book from Boston to Marseille all on one ticket. In addition to reducing risk, you won't have so many connections.

If you are booking on separate tickets, make sure you understand all the risks. Here's a good summary: https://www.tripadvisor.com/Travel-g41707-c207311/Newton:Massachusetts:Connecting.On.Separate.Tickets.html

If you are changing planes in Heathrow, they have a wonderful connection website. Put in ALL of your details, and you can see the steps involved and estimated times. Note the disclaimer on that page, that these times only apply if you are all one one ticket. http://www.heathrow.com/flight-connections

Here's a guide for changing terminals at CDG. Again, note that the minimum times only apply if you are on one ticket, so you must allow lots of extra time if you are on separate tickets: http://easycdg.com/passenger-information/connecting-flight-connections-paris-cdg-airport/where-to-go/

I would go by train😘....3.5 hrs ....no security...sights ...room to move....plane is 20 to 25 minutes less...hard to imagine!!...direct from CDG....or go from London ...add 3 hours to the travel time....much more relaxed and mabe cheaper...I'm doing it in Nov.... check "snfc"... or try google Paris to Marseille train

Have fun...try the train!!!

...and they go approx 1/ hour i think

CDG is a nasty airport...delays all over. Ive missed flights there many times.

The train is usually the preferable option, but not if you're already at the airport.

I agree, see what you can do to get a flight to Marseille as part of your entire booking rather than as an add-on.

Use a multi-destination search function for one ticket from Boston to Marseille, probably through CdG but it doesn't matter where you switch planes. Aside from the convenience, it may be cheaper than buying a separate French ticket. And you can fly home from another city, also an efficient tactic. But these must be bought together, not as single fares.

Planes fly from London to Marseille, too. This itinerary is unnecessarily complicated.
