  1. I am a flight attendant for a nationally known airline. I am concerned how all of this will affect us. It seems to me that these new rulings are going to change the way our own work rules apply to our schedules. Please inform. Thank you.


    1. Donna,
      It will most certainly have an impact. Not sure whether your airlines assign crew as “Teams”, if so, even if the FA’s operate under 121 subpart P and not under the pilot rules, they will most likely end the duty at the same time as the pilots. Gone from the pilot rules is the concept of compensatory rest following reduced rest, while the FA’s still have this concept. so even if the pilot has had a 10 hr rest period before starting a FDP, the FA could have been required to have had a 12 or 14 hr rest period, so as a team, the pilots will need to wait for the FA’s to be legal.
