Uber to the nearest Dart train station Inwood/Love Field (would think it would be less than $10). Then $3 on Dart train Orange Line the rest of the way.

Or a dart bus will get you from Love field to the Dart station (included in the $3) as someone mentioned above.

But I hate buses. The Dart train will take you to DFW Terminal A. Check-in through security at Terminal A (have to walk 5 min for TSA Precheck).

Then take the SkyTrain (post security) to your Terminal.
