The medical is a standard medical. Hippa laws only allow DAL to get a "yes," or a "no."
They have you do a hearing test, a few eye tests, some fasting blood sugar test, cough left and right, ekg, etc. Like I said, it is a normal initial work or annual physical.
If you have a medical waver for something, or it has been cleared with OKC, bring the paperwork and save yourself the time with doing it later.
