The end of career pay you’d be giving up is $350-450K+ per year. Subtract your simP pay and that’s the cost of being home every night.
And then you’d be applying to the airlines as an X years non current guy. Which increases the likelihood, and length, of the RJ seasoning your resume/application might need. At a cost of $350-450K per year minus your regional pay.
Typical staff officer options to stay current might include CFI’ing on the side. How much ‘family’ time does that take?
Ask your airline buds how much they would work, and nights away, if they min run their early years at their airline? Ten days per month? Five to seven nights away?
Is the sim job $100K? A four year delay starts at $1.0 to $1.4 million. And then there’s being less senior every year in the interim.
That’s why few guys pass on ‘keep pressing’. It’s big numbers and a long term QOL impact.
Good luck. Just throwing out data.
