So I just got a schedule for upcoming PVG-DFW-YYZ where the connection time at DFW is only one hour precisely in April.

AA 128
4:50 PM PVG
5:35 PM DFW

AA2584
6:35 PM DFW
10:36 PM YYZ

Now, I see that MCT at DFW for I-I is 70min so I'm not sure how this has cleared their automatic rebooking system, but what's the likelihood of the above connection happening? I checked other flight times and none looks better. I am familiar with DFW and have GE/Precheck, no luggage to worry and previously I've walked off HKG-DFW and through security in about 15 mins after arrival so I think even at 1 hour mark I should make it ok, but likely no time for lounge/shower.

Question is, will this work if I say nothing to AA and just check-in as normal, or will the system find the MCT issue at boarding/check-in and try to re-route me? If it's the latter then I'd rather find my own desired route now instead of departure day.
