I would argue there is no better job in the world than living in a large legacy hub that is likely to never go away. The flexibility it allows is unmatched. Bigger planes, smaller planes, 1 day turns or 5 day internationals. Want to sit reserve and not work during slow months, want to make a little extra, picking up trips is easy and readily available.
While you missed the biggest part of the retirement wave, that would ensure super seniority for a career, there is still plenty of the wave left to ensure you make it to DFW very quickly and are able to stay there likely for your career.
