We should determine class seniority by how people perform in the simulator.
On day 1, BB should take everyone over to the 738 sim and whoever lands the furthest down the runway and still stops on the runway, is the most senior.
Then we can either work it from there by distance. Or take the best pilot and the worst pilot and let them pick the other pilots seniority similiar to how you pick a sandlot football team. Let the best pilot pick the top down of the seniority list and the worst pilot pick the bottom up.
