Flights from Detroit to Dallas to Mexico

The two choices I am considering are both on American Airlines:

Leaving Detroit at 5:07am, 4 hour 51 minute connection time in Dallas, next flight to Merida, Mexico.

I have not figured out whether I have to collect my bags and recheck them and/or whether i have to go through security again in Dallas. I am in average to good health. I walk faster or slower than others depending on the situation and how much of a hurry I am in.

2nd option: Leave Detroit at 7:58am. 2 hour connection time in Dallas. The same flight from Dallas to Merida.

Is 2 hours too short? Is 4 hours 51 minutes ridiculously long or much safer? Do you see a definite advantage to either choice?

Assuming it's all on one AA ticket, you will not have to recheck bags or go through security again at DFW. Obviously you have a lot more cushion with the earlier flight, and since that one is so early it is probable that your plane will be at the gate overnight and it will be its first flight of the day, rather than a turnaround of an incoming flight, which substantially reduces the possibility of delay. Another thing to consider is that there is likely only one flight daily to Merida so if you missed the connection you'd probably need to wait in Dallas until the next day. But on the other hand you'd need to get up insanely early to catch a 5:00 am flight no matter how close you live to the airport, and nearly 5 hours is a VERY long time to wait in DFW. If there's no significant price difference personally I would go with the two hour connection as that should be plenty of time (many connections are much shorter than that), but there are pros and cons either way.
