Connection time Paris CDG

You should not have any problems with this. It should take you about 20 to 25 minutes including security.

CDG has not been as bad in recent years as it was 10 or 15 years ago. Unless there are strikes or some other delays you should not be stressed to connect.

We have flown Air France several times, since AF is in the Delta network. Also, we like Air France.

We have made the transfer from 2E to 2 F a few times. You can walk through without having to go through security again.

I always plan on 2 hours for a transfer, but usually have some time waiting for my next flight to leave. You will be arriving early, which is a plus. I think you can make it, but if you can book something with 2 hours, I would do so. If you miss the connection, the worst thing would be they would put you on the next flight.

Wait a minute: Paris to Prague is a Schengen interior flight, right, like Cleveland to New York. So wouldn't icem2829 have to go through passport at CDG? Correct me if I'm wrong.

I do know there will be a security screening entering the second terminal whether an internal or external transfer--that I just experienced transferring between the two terminals although I didn't need to go through passport because I was coming from and going to two non-schengen countries (Armenia to US).

No matter, it's on one ticket so AF will put you on a later flight if lines are long. Comfort won't be much comfort after the first flight.

Bets -- I second you on both counts. OP has to go through passport control in Paris because Paris-Prague is an internal Schengen flight, and OP also has to go through a security screening because CDG's terminal layout requires that all arriving non-Schengen passengers be re-screened before getting to the gate for their onward flight.

Yes, I do know I will have to clear passport control and security in Paris as Prague/Czech Republic is also is Schengen. The problem is the next later connection would be a 4 hour connection, just seems like a waste of time on what is already a pretty short trip. And I assume they would get me on that anyway if i I miss connect, as long as there are seats. I also noticed that the originating flight, AF 23, has a very good track record of not only on time arrivals, but arriving like 30 mins early. So in theory this connection may end up being closer to a 2 hour. I will probably chance it, just curious as to if anyone had done a very similar connection and how long it took gate to gate.

Icem2829, just a heads up. Twice when I transferred from 2E to 2F to catch connecting flights some of the 2F gates will have two different flights leaving within 5 minutes of each other. My flight to Switzerland was sharing the same gate with a flight going to another country, both planes were parked at the gate. The walk way split to the Left & Right.
Enjoy your trip.

Thanks Brush. Do you remember how about long it took you to get from gate to gate? Assume you did passport control as well?

we've been through CDG 3 times in the last two years - one ticket connecting to Marseille, Florence and Vienna ... we have never taken less then 2 hours. And we have been both Premium economy and business class. You just never know when a big travel group is coming through or a strike or something else.

2-2.5 hours would certainly be more ideal, but the next option is 4 hours. I’d rather try to 95 mins then sit around all that time. Do you happen to recall how long your gate to gate connection took?

CDG isn't my prefered hub, but 90 minutes is generally (just) adequate assuming your inbound is roughly on-time. Given that things happen, having the fall back being a later same day flight is a good option. And if AF can't get you on the later AF flight should AF23 be delayed, you can try pushing for a Czech Air flight to PRG.

While AF 23 may be reliable, thing do happen.

AF23

left GATE TM1 John F Kennedy Intl - JFK SATURDAY 18-JAN-2020 07:11PM
EST (2 hours 31 minutes late)

arrived at TERMINAL 2E Charles de Gaulle/Roissy - CDG SUNDAY
19-JAN-2020 07:43AM CET (1 hour 53 minutes late)

Note that the AF23 pilot was able to make up 38 minutes of the late departure but not enough. Hopefully you don't have January 18th weather.

I would buy the 95-minute connection time ticket.

In October 2019, I arrived on the 5:50 flight from JFK at 2E (about on time) and had a 7:10 departure to Berlin out of 2F. Passport control and security lines were minimal that early. Gate to gate was around 25 minutes. I arrived at the departure gate well before boarding time. I was in business class, but your time shouldn't be that much more in premium economy.

In 2016, I got a dirt-cheap business class fare on the early morning flight from Atlanta with a 55-minute transfer time to catch a Budapest flight (again, 2E to 2F). Immediately after buying the ticket, the arrival time changed and the connection time went to 45 minutes. The ATL to CDG plane arrived 15 minutes late. I made it to the 2F Budapest departure gate 5-10 minutes before departure; happily, the door was still open. I made it with my carry-on, but my checked bag of American goodies for my friend in Budapest arrived late that night. I think they may have held the Budapest flight a short while because a handful of stragglers got on the plane after me.

Here is Air France's take on transfer times (which includes a video): https://www.airfrance.fr/FR/en/common/guidevoyageur/aeroport/temps_parcours.htm

I lucked out. I walk past another airline that was just unloading and made it through in less than 30 minutes. Followed the signs to get from Terminal 2E M gates to 2F, there was a bag check/x-ray station everyone went through first then got in line for passport check and headed to my gate to Switzerland in Terminal 2F. I try not to stop off at the restroom until after clearing Passport Control, especially when there are two large aircraft unloading at the same time. Since I traveled Premium Economy on Air France I went through a shorter line at the security check, the regular line had 2 or 3 bag/X-ray stations & it seemed to move pretty smoothly. For my last 3 trips transferring at CDG the shortest was less than 30 min. and the longer was under an hour. Just, lucky. Now Frankfurt is another story with longer processing times.
I will get to experience it again at the end of this November when I do my Christmas Markets trip.

What will you do if your transatlantic flight is delayed over an hour and you miss your connection assuming it is all on one ticket?

The following flight that leaves 4 hours later could be oversold so then you would have to wait until the next flight to PRG with available seats which could be the next day.

Four hours may seem like a long time, but it is insurance in case you miss your connection because of delays and the following flight is oversold.

My recent international flight out of JFK on Delta was delayed over 2 hours because of winds and only one runway open for both landing and takeoff. We only made up 30 minutes of that delay from strong tail winds. That’s it.

Thank you all for the responses. As it turns out my friends ended up getting mileage tickets on a flight through AMS instead. So I am going to fly with them. Price was about the same for me, so not an issue. Not because I was too worried about the connection, more so just so we are all together. Doesn't seem like I will need to worry about the AMS connection, and from what I hear that airport is far more efficient that CDG. My connection on the way back is via CDG, but with 4 hours. So lots of lounge time there!
