DL73n......$219/HRX80X12=$210K
AVG 1000HS/YEAR with 5% at premium rates 1000x.05=50hrsx219x2=$21k.
It adds up to about $230k/yr. On avg.
I have heard of one 73n who reached mid 400s. And more than a few reaching 300k. But we are talking about a select number, maybe top 10% in category and working their azzesoff.
As Timbo cited.... there are similarly situated FOs who are averaging 150hrs+/month for pay using the lca/gs model.
The last one I flew with in that boat looked exhausted, and at layover it was the first time I ever wondered if my copilot was going to even wake up in the morning.
