Right. The first 20 slots per month are reserved for eligible Compass pilots. To be eligible you must be a Captain and have at least 30 months of employment after the first person in you new-hire class passes their check ride (Effective Date of Employment, we also get longevity pay increases on this date, it's stupid). Only 25% of the seniority list can flow up in a rolling 12 month period.

Clear as mud, right?
