USX.....isn't that a railroad?
Every airline monitors route load factors, per day, per month, per year. That is they determine what size aircraft to use.
Planning for freight by day, fuel, meals, is watched very closely.....If a A380 has load factors overal that a 744 could handle, then trust me, there will be an equipment change. And vis-versa.
