Relatively recent new hire here (2/18). Excuse my ignorance, but how do you determine the cutoff for line holders at the various bases? I’m trying to compare DTW and ATL for a 200 FO. I’ve seen posts in this thread in the past with updates for each base, but was trying to learn how to determine it on my own so don’t have to keep bothering you all for a new summary. Thank you for your help.
