Greetings:

I will be flying from Monterrey, Mexico back home to SFO on a Tuesday. American has us booked with a connection in DFW. There is one hour for this connection.

Does this seem cutting it too close? One hour is short for a domestic connection, but coming from out of the country means waiting for luggage, going through customs, racing to the domestic terminal and going through security. Seems like a lot to do in such a short interval. We are going to a wedding, so carryone luggage is not an option.

The agent on the phone thought that should be sufficient. Has anyone done this? Can I look forward to missing the connector and waiting at DFW for hours for the next flight?

If you haven't already, you might want to go to the AA Forum. all of my experience in DFW has been away from AA.

As an aside, 1 hour doesn't really seem like enough.

Good luck.

There's NO WAY you'll make that connection. DFW has multiple terminals, with a not-very-fast train connecting them. It's very unlikely you'll have a connecting flight in the same terminal. And, since you have to get luggage, then re-check it, that will add 30-45 minutes. I'm not even counting the time to clear Customs.

Assuming you are connecting AA to AA, there is a small chance you will make that connection. Customs & immigration are typically pretty quick at DFW Terminal A (which is where all AA int'l flights arrive). Once you drop off your bags at the AA bag recheck counter just outside of customs you proceed upstairs and are right at a security checkpoint to go back airside (at approximately gate A37). All of the AA terminals are connected by a tram inside security and also walkways. Note that unless you are a very slow walker it is almost always better to walk and NOT take the tram.

Insiders tip - because the checkpoint lines at A37 can be longer than others because of all the int'l connects re-clearing there if your connecting flight is departing from one of the more northerly A gates (A1 - A30, give or take) in Terminal A, you can sometimes save time by walking north through the ticket lobby/bag claim areas to the next checkpoint before going through security.

I have almost always gone from plane's arrival to out the terminal door in less than 30 minutes (US citizen, with carry on only) when arriving int'l at DFW, so I am willing to say you at least stand a chance with a 60 minute connection. But it will be tight. Give yourself 85 minutes and I'd say no problem.
