There is a old saying, “You never turn down a command.” Even going from jet down to turboprop you still took it as that was when your career really started.
As always there were a few exceptions, older pilots who were on a desirable fleet with a good base who didn’t want the bother of a upgrade and conversion together with moving house. With various allowances factored in you could be worse off financially and not have the seniority to get back on your desired fleet.
Three trips a month in a wide body vs multi sector days in a turboprop could swing it for some people.
