Dallas was just a connection while going to St. Louis. Keep that in mind when reading the rest of what I describe here.

Airport

The airport is quite big. I had to use their Air Train to get to another terminal for my connection. I was lucky to not have baggage checked-in, because I would have to re-check and go through security again before going for my connection.

My flight was delayed and the airport crew was not very concerned about people having only 30min to get their connection. I have a feeling they didn’t make it on time and had to reschedule.

Keep in mind that, if you’re coming from an international trip, you’re going to leave the plane, go through passport control, get your bags, go through security again, check your bags again, and then get your connection. Plan accordingly so you will have enough time to do everything.
