Its not rocket surgery. Why the heck would the company pay 150% for all open time like they did in Nov when there's enough volunteers and RSVs at straight pay to cover most of the open time.

Then when needed, the JA incentive is usually accepted at the last minute with little effort on their part. It might be cumbersome for scheduling, but its keeps the pilot payroll lower.

Who would pay premium all the time when basic works most of the time ?
