People that live and work on separate islands, how do you do it?

I’ve always been curious about how people that live on one island and work on another do it. How does transportation, sleep schedules, job duties…how does all this and that work?!?! Is everyday an early morning and a late night to catch an airplane? Are the airplane tickets pre-scheduled and paid for? Do you stay at the other island so many days of the week? Car rentals? Apartments? I just wanna know!

I’ve always been curious but as of rn, I’m job hunting and there’s some jobs on other islands that are interesting but I would like to know how everyone makes it work to see if that’s something I could commit to. Any and all stories are welcome!
