I think the reason they stopped in JFK is because the pilots were only 'legal' to get to JFK. FAA only allows pilots to fly for so long before mandatory rest and I guess the extra few hours to DFW would make them illegal.

That's probably true, but I wonder about the rules when there is an extra pilot aboard, as there almost always is on a route that long.
