If you are at EZY or RYR as a captain in a base you want in your early to mid 30’s if it were me I would happily stay put. If it’s about money it’s no contest. If you must do Long haul then you must move. That however comes at a cost. A vastly reduced salary and years and years (most of the time and in most cases) as a FO. Nothing wrong with that it just depends on what you want. I know a number of guys who are very very happy in the locos. I also have friends who are in their 40’s in the majors and are very happy to kick back on a long haul fleet and never want a command. They work part time and love the lifestyle.
Sounds like you have to make a decision. I would start with job security, then look at lifestyle and then money. That’s me now though, it’s not always been in that order.
