And another question here....

Pilot Relative Position

Is this chart based on seniority to hold a line in each base / acft or does it show seniority needed to just sit reserves in each base / acft?

Originally I thought this was seniority needed to hold a line, since showing a line number to sit reserves wouldn't make sense because that would include, somewhere, even the plug from today's class. You don't need seniority to sit reserves somewhere in the company.

Yet look at the NYC -88 FO number....12,927. Obviously there's more than ~ 73 pilots sitting reserves in all of DAL.
