79 on the seniority list for 2019.
48 since Mar 4 class. So averaging 16 per class every week now. If they start 1 class per week starting yesterday, that will bring 64 per month.
For someone on the list right now, that means their relative seniority will grow by 4.4% a month just by growth. If XJT keeps sending 20 per month to UA and 20 to others (retire, or other airlines), you'll move up by 104 spots a month - a relative move of *7% per month*.
To hire 600 as repeatedly stated they will, that means they will need to keep up this pace for the rest of the year - 8 months and change.
If that happens, someone on the bottom of the list now will have a seniority close to 50% by Christmas. Upgrade times will drop through the basement. I doubt anyone hired in March will have to fly weekends or holidays if they don't feel like it.
I know this is pilot math, but if this is even close to what actually happens, this will be one heck of a wave.
