Yes, assuming you pass all the "objective" medical/psych/motor skills tests most interviewers will tend to lean in your favor (unless your dad personally pizzed someone off). Make sure you learn as much as you can about the "objective" tests.

Do your damnedest to meet minimum eligibility before your dad retires. All you really need is a 1000 hours turbine SIC...start picking up trips on your days off.

DAL is your best shot...your dad can't help you much at other airlines.
