Quick question about dead-heading. I have my first IOE trip on tues so they are dead-heading me to MIA meet the Chief Pilot and then dead heading me to ORD for my trip. The verbage in the FM1 is not totally clear. Am I required to wear uniform while dead-heading or just first class attire acceptable? If the latter then would it still be acceptable to be meeting my CP in first class attire or wear the uniform?
