All of this is very likely extreme outlier behavior. Tempest in a teapot.
Would be interesting to see a statistical breakdown of hours flown vs. credit hours billed per year. Preferably on a base/equipment/position/seniority breakdown.
I suspect most of the lowest paid flying (no premium/payback) and highest block hours are either unsophisticated PBS users or are just happy going to work and making more in salary than 95% of the US, if not the world. It’s a job, not a piggy bank. Delta is not Santa.
The backbone of the airline, as it were. Somebody has to actually show up and, you know, “work”. (Still the easiest, highest paid job I’ve ever had, by far)
To each their own. Contract snipers are definitely contractually compliant, so more power to them, I guess.
