Arrived in DFW on QR in Biz on the 4pm flight and transferred to AA on an 8ish pm flight which was of course a bit delayed for cabin crew to arrive.

I have GE but my ELDERLY mother who does not have TSA precheck or GE and she got an amazing gal who pushed her wheelchair past lots of people in the VERY long line at customs.

There seemed to be a lot of confused passengers at that hour in the immigration line(looked like staff were herding cats-no joke!)

She made it to baggage claim before our bags got offloaded!

So, if you have GE AND Precheck a 2 hour window to make your AA flight is totally doable. AA does honor TSA precheck.
If I had been traveling by myself I would have booked an earlier flight home from DFW than we did-travelled on award miles so I was not going to complain!
I made it through GE and customs in LESS than 5 minutes. It was a breeze.
Hope this is helpful
