Not sure to your entire question Dr., but I had a heart procedure that required 3 months of sit time and medical on hold as a result. So 3 months short term disability and medical was cleared. I called Delta at 5 p.m. on a Wed. Afternoon, at 5:30 got a call from training to report 2 days later for quick mini requal course! So don't be surprised when you call in well to possibly be scheduled immediately for 737 school. Welcome back by the way.
