The OP can't be clearing US entry in Dublin, the flight Dublin to Paris is operated by "City Jet Dba Air France" so I suspect will transit CDG without passport control.

In any event it's probably on Delta to get OP home assuming one ticket. There will be many Air France and Delta routings home to SLC if plane is missed.

The OP won't be pre-clearing US immigration/customs at DUB nor will the OP go through passport control at CDG. This is a fairly straightforward connection with only security to clear.

I am so confused. She is going to the US but is going via France so she doesn't have to go through US customs and immigration at Dublin? She will do it when she arrives back in the US? If she was flying directly from Dublin to US then she would have to go through US custom and immigration in Dublin? The time difference is a biggie. 1:45 is a legal connection and you should be ok. Are you doing only carry on? My girlfriends jump in with some group one time in Frankfurt and were helped to their connecting flight leaving me who was sitting elsewhere on the plane waiting for them. I ran to connect and then the plane was late. Did have to get stamped and security all over again but there were helpful people.

The OP will go through US immigration/customs upon landing in the US. Preclearance would only apply if she's taking a US bound flight from DUB.

Both flights arrive and depart from the same terminal, CDG 2E. There appears to be 1 hour 20 minutes between flights, at least tomorrow there is.

It's the airines problem. Not the passengers. The airline set up the itinerary and the passenger is booked through. If the connection is missed, which it probably won't be, the airline is responsible for getting them home.

At some time in the future, there will probably be US immigration clearance in Paris, but it is not likely to happen soon, since France is a strict believer in reciprocity and the only country that has French immigration clearance on foreign soil is the UK for the Eurostar rail service, since the UK does the same thing in Paris.

As for customs clearance, it absolutely never happens on foreign soil since passengers from anywhere can exchange all sorts of items in the international transit zones of airports.

I should qualify that last statement with "except for Canada" since Canadian airports have isolated zones with passengers going exclusively to the United States.

And now that I wrote that, I realize that the UK and Eire have obviously done the same thing, since they always bend to the will of the big country while receiving no compensation.

Patty, that is what I understood. I think she is fine and has enough time. Doing a hop from Dublin in May to Germany and have done them before to UK and no problems. But when going straight through to US have to do the US customs and immigration thing in Dublin.

I don't think there's any US customs preclearance at any airport in the UK, although there is at both Dublin and Shannon airports in Ireland. For passengers to the US who have to make a domestic connection, meaning they have to pick up their bags at the first US airport, go through customs, and recheck the bags before the domestic flight, this would be an incentive to use Dublin or Shannon as their departure airport, bringing more business to Aer Lingus, I imagine.

As to the original question, I never worry about short connections when I'm on a single itinerary, with the airline responsible for getting me to my destination. I've several times missed connections in these circumstances and it was never a problem. The airline has sometimes even put me on a flight on a different airline.

I once even arrived at my destination earlier than I would have if I had made the connection. I was going to Philadelphia, but bought a ticket to Newark, because it was a lot cheaper, planning to take the train from Newark airport to Philadelphia. When I missed the connection (Lufthansa, in Munich) I told them my final destination was Philadelphia and they put me on the direct flight to Philadelphia.
