"Most of my legacy friends that are senior fly domestic. More flexibility in schedules and overtime."
You need more friends. If w/b international is an option it goes more senior.
2500 n/b CA's. If you're #1000 in the company you'd be top 2% on n/b domestic. W/B long haul? You'd be 78%.
If you're #2000 you'd be top 9% n/b domestic. W/b long haul? You're too junior to bid it.
The #1 n/b domestic Captain would be at the 37% mark on w/b international.
The guys flying the trips knows what works for them. Pay, time off, ease of work. W/b international goes more senior. Of course there are exceptions and outliers.
