Boomer, Ol' JAWs is here to vouch for crju and the IAH-DFW/DAL flights. I do this trip occasionally and upgrades are near impossible. But, it's a 40 minute flight and basically, who cares, except for the "accomplishment" of upgrading. Since CO Express started service to DAL (no upgrades anyway) I just take their flights because of convenience. The Regional Jets are just fine for a 40 minute flight.
