Certainly it's been mentioned before, but obviously the company isn't getting the word out on verbiage THEY put in the FOM. Biz casual or uniform y'all. No jeans, sneakers and a shirt with a collar.
Had a JSer yesterday show up. With all of the aforementioned clothing. Of course I took him, but let him know that some captains likely would not. Curiously he was a commuter with @ 18 months with the company. In his defense he commutes solely on DC and OAL, so he was unfamiliar with DAL policy on this matter.
Anyway please don't put a captain in this position.
