I got on with F9 in 2015 before they opened LAS where I live.
If they had not opened LAS I would have probably left a while ago. But I’m in my mid 50s.
Not commuting is worth over 100K a year to me.
I still have concerns about the ground handling and cheapness of the operation. You can only go so cheap before stuff will happen. - like MSY
You say you have 30 years left. A lot can happen in that time. Maybe F9 will be the next SWA - who knows. Keep the board posted on you’re decision.
