only an hour each way, the strange thing is there's no option at the physical check in kiosk or in the app to attach a JMB number: https://i.imgur.com/Z46zQAV.png

so i had to go ask a staff to attach it on my outbound. they reprinted my ticket but there wasn't any indication about what program that number was for... seemed to look fine for my return leg though. its been less than two weeks so i guess ill wait

EDIT: oops i read that as how long was your flight. my flights were within the last week
