And why would that be? We have 13/14 days off per month, some lines have 15-16 days off.
Is the 73 a money maker? No. A time building fleet? No. Is Atlas or any other ACMI company in general an ideal job for someone that loves "home time"? I don't think so, but it also depends since you'll enjoy longer blocks of days off with your family.
Other jobs out there will offer more family time or at least on a more regular basis.
But as per usual, there are pros/cons and it depends on each person.

As a reference, I left on December 8th and I'll be back on the 23rd, pretty standard.
