I just dropped my schedule down to 52 hours and 24 days off in January for family reasons as well. I am a very junior line holder on the 777 at United. Been here 5 years. We can drop our schedule down to 0 I’ve been told. It seems doable most months with the possible exception of summer. Haven’t tried it yet. I’m not in love with the flying on the 777, but the schedule is the best I’ve ever experienced at any flying job on any aircraft.
