You do know that the Atlas seniority lists, while published on the 15th, are representative of the situation at the end of the prior month? It says that at the top of each page. And that 1741 (the Nov 30 number of Atlas pilots) minus 1724 (the Dec 31 number of Atlas pilots) is 17?

Still, losing one every other day is impressive. The Jan 14 class of 23 will just balance out.
